2005-7 PRODUCT GUIDE Fiber-Optic Devices TOSLINK semiconductor http://www.semicon.toshiba.co.jp/eng TM TOSLINKTM Optical Transmission Devices TOSLINKTM is a family of data transmission devices that use optical signals instead of electrical signals. Because TOSLINK uses an optical fiber cable as a transmission line, it provides the following benefits, compared to electrical transmission using a twisted-pair or coaxial cable: The transmission line (i.e. the optical cable) is not susceptible to electromagnetic interference. The optical cable does not radiate any electromagnetic noise. External appearances of TOSLINK The optical cable provides a complete galvanic isolation between equipments. Comparison of TOSLINK devices and photocouplers A photocoupler is a semiconductor that consists of a light-emitting device and a light-receiving device molded in one package. It is used to provide electrical isolation between input and output. In contrast, TOSLINK uses separate light-emitting and light-receiving units that are connected through a long optical cable. Because an optical cable is used as a transmission line, it is possible to transmit signals over long distances while providing a galvanic isolation between the transmitting and receiving ends. Thus, TOSLINK can be viewed, in a sense, as a long-distance photocoupler. VCC VCC Output Input (a) Photocoupler VCC VCC Input Output Optical cable Optical transmitting module Optical receiving module (b) TOSLINK Comparison of a TOSLINK device and a photocoupler Electrical and optical transmission systems In an electrical data transmission system, a line driver is used to drive electrical signals through a long transmission line such as a twisted-pair cable. At the other end, a line receiver compensates for signal decay by amplifying the signals. A connector is required at each end of the cable. By contrast, in a TOSLINK-based system, a transmitting module converts electrical signals into optical signals, and a receiving module converts optical signals back to electrical signals. An optical fiber cable is used as a transmission line, and optical connectors link the transmitting and receiving modules to the cable. The TOSLINK transmitting module incorporates a light-emitting diode and driver circuit. The TOSLINK receiving module incorporates a photodiode and waveform reshaping circuit. The interface is either TTL or PECL for both modules for easy connection with other peripheral ICs.

Data transmission systems Optical fiber An optical fiber consists of a core surrounded by a cladding. An optical ray entering the fiber is reflected back at the boundary between the core and the cladding. In this manner, it travels along the length of the fiber. There are three kinds of optical fiber: a) All-plastic fiber (APF) b) Plastic-clad silica fiber (PCF) c) Silica fiber Optical ray Sheathing Cladding (low refractive index for confinement of light) All-plastic fiber, having a plastic core and plastic cladding, is used for shortdistance transmission. A plastic-clad silica fiber, which consists of a silica core and plastic cladding, is used for mid-distance transmission. Silica fiber consists of a pure silica core with silica cladding and is used for long-distance transmission. Each optical fiber has a lower transmission loss over a certain wavelength range and is used together with appropriate optical modules. Core (high refractive index for transmission of light) Structure of an optical fiber TOSLINK circuit configurations Optical transmission module The LED is driven by a differential circuit to reduce current transients generated during the on-off switching of the LED so that the LED's switching does not affect peripheral ICs. Transmitting IC LED Input 4 VCC 3 IF-CONT 2 GND 1 Transmitting module Optical receiving module The receiving module employs an ATC (automatic threshold control) circuit to reshape the waveform. The ATC circuit controls the comparator reference voltage so that it is always automatically adjusted in accordance with the input optical power. This minimizes pulse width distortion, regardless of the length or bending of the optical fiber. Receiving IC 4 GND2 Amp circuit Comparator 3 VCC 2 GND1 Reference voltage generating circuit 1 Output ATC circuit Receiving module TOSLINK package constructions There are two package types available for TOSLINK optical modules. One is a molded resin package for ordinary applications. The other is ceramic, used for applications requiring exceptionally high reliability. The structures of these two packages are shown in the figure on the right. In the molded resin package, devices are mounted on a leadframe and molded with transparent resin. In the ceramic package, devices are mounted on a ceramic substrate and hermetically sealed by a metal shell. The ceramic package provides better resistance against humidity and temperature than the molded resin package.

General-purpose optical modules come in two versions: simplex types compatible with F05 connectors and duplex types compatible with F07 connectors. All general-purpose optical modules are housed in molded resin packages. Whereas the 170 Series requires the external resistor value to be adjusted according to the transmission distance, the 190 Series needs no such adjustment. The figure at right illustrates the dynamic ranges of the 170 and 190 Series. The 190 Series offers a dynamic range more than 6 dB wider than the 170 Series. Dynamic ranges of general-purpose TOSLINK modules Application circuits Application circuits for the TOTX197 and TORX196, a pair of transmitting and receiving modules, are shown in the figure on the right. The TOTX197 transmission module requires an external resistor to supply current to the LED. The TORX196 receiving module requires an inductory capacitor noise filter on the Vcc line. The module case is made of conductive resin to provide a shielding effect against external noise. Pins #5 and #6 must be connected to the system ground. There are also duplex modules in the general-purpose TOSLINK series; their application circuits are generally the same as for simplex modules. All the general-purpose modules have a TTL interface for easy connection with peripheral digital ICs.

This receiving module, designated the TORX198, provides an analog voltage from the internal amplifier, which changes with the optical power input into the receiving module. Hence, by monitoring the analog output it is possible to measure optical power without dedicated optical power meter. Incorporating such a feature in your system helps to simplify optical power measurements for regular system maintenance. When optical flux monitoring is not required, the TORX198 handles digital data transmission like the other TOSLINK receiving modules. In this case, the analog output pin may be left open. Toshiba's TOSLINK offerings also include a duplex module with an analog output, called the TODX298, which is targeted for a PCF cable. 5 4 Ta = 25C, VCC = 5 V With APF 3 2 1 0 -30 -28 -26 -24 -22 -20 -18 -16 -14 -12 -10 -8 Received optical power (dBm) Receiving module with an analog output for optical flux monitoring Ceramic-Packaged Optical Modules Toshiba offers several TOSLINK modules housed in ceramic packages that have higher reliability than plastic molded packages. In ceramic packages, devices are mounted on a ceramic substrate and hermetically sealed in metal shells. Ceramic packages provide superior moisture resistance and also reduce the stress put on the internal LED, leading to longer life. Structure of a ceramic-packaged optical transceiver module The figure on the right illustrates the structure of the optical transceiver module housed in a ceramic package. The transmitter section consists of an LED, a transmitting IC that drives the LED, and a chip capacitor mounted on a ceramic substrate. The receiver section consists of a photodiode, a receiving IC (which contain a waveform-reshaping circuit) and chip capacitors mounted on the same ceramic substrate. Both the transmitter and receiver sections are hermetically sealed in metal shells with glass windows. The transceiver module is installed in a case to be attached to an optical connector and fastend from the back of the case.

SMI connectors are suitable for digital home appliances. While SMI connectors are very small, about the same size as audio simplex connectors, they provide high-speed, full-duplex transmission. PN connectors are an improvement over JIS F07 connectors that have been widely used in industrial applications.

The interface level and fiber optic connector configuration conform to the Digital Audio Interface (DAI) standards respectively. These modules are therefore ideal for a wide variety of applications, ranging from audio equipment such as CD, MD and DVD players to sound applications for personal computers and computer entertainment systems. To meet customers' specific needs, Toshiba offers digital audio optical modules in three types of packages: a standard package (panel mount type), a medium-sized package (for PC sound cards) and a mini-package (for portable devices).

Reliability In an optical module that has been in use for some time, nearly all of the deterioration in characteristics is due to a reduction in the fiberoutput power (Pf). This is due to deterioration over time in the level of optical output of the LED used as the light source. The drop in the LED's optical output is thought to be caused by crystal flaws in the wafer or stress in the mold resin, although the detailed causes are not clear. Although LEDs used for optical communications are generally considered to have an almost infinite lifetime, their optical output does fall over time. The life of light-emitting devices is greatly affected by the operating conditions and operating environment as well as by the lifespan characteristics of the particular device.Toshiba recommends that the user first check a device's lifetime characteristics before selecting it and setting its operating conditions. For information on reliability, contact a Toshiba sales office. Regular maintenance, such as a check on the amount of light emitted, is recommended. In the case of the red LEDs used in the TOTX195 and TODX297, for example, a light-absorbing layer may form on the surface of the LED as the aluminum in the liquid crystal oxidizes, causing the optical output to fall. Since this tendency is pronounced in high-humidity environments, it is recommended that products containing red LEDs not be used in such environments. For high-humidity environments or applications requiring a long lifespan, Toshiba recommends a TOSLINK ceramic-package optical module. 2. Soldering Optical modules use semiconductor devices but are essentially optical components. When soldering, ensure that flux does not adhere to the light-emitting or light-receiving surfaces. Take the same care when cleaning off flux after soldering. Some optical modules include a protective cap. This cap is intended to prevent accidental operation when the module is not in use. It is not dust- or waterproof. Because the optical module is an optical component, Toshiba does not recommend soldering methods or postsolder flux cleaning methods in case where flux could affect the module. Toshiba recommends first soldering without mounting the module, then cleaning the PCB. The module should then be hand-soldered and no subsequent cleaning should be performed. If it is not possible to hand-solder the module, one way of avoiding the effects of flux is to use non-halogen (chlorine-free) flux, taking care not to leave chlorine or other residue, and omitting the post-solder cleaning. In such cases too, the reliability of the device must be checked. Be sure to check the reliability of the device. 3. Noise Resistance The case for the TOSLINK (simplex) optical receiving module and (duplex) optical transceiver module is made of conductive plastic. The case is designed to provide shielding against noise when the reinforcing pin at the front of the module is grounded. When the module is used, this pin should be connected to the signal ground. Since the case for the optical receiving module and optical transceiver module has a resistance of several tens of ohms, ensure that the case does not touch the power line or any other circuits. Generally, the use of optical transmission devices is considered to improve noise resistance. While optical fibers are certainly not affected by noise, optical modules, particularly receiver modules, are comparatively easily affected by noise because they handle such minute current signals. To improve noise resistance, the TOSLINK case is treated to make it conductive. However, since the signal output from the optical receiving modules photodiode is a minute current signal, in some environments simply shielding the case will not protect against noise. When using a TOSLINK device, conduct live tests to check noise resistance. A simple noise filter is mandatory for the power lines for the TOSLINK optical receiving module and optical transceiver module. However, in the case of significant power supply ripples, further filter reinforcement is also necessary. In addition, when the optical module is placed in a location susceptible to emission noise, Toshiba recommends covering the optical module and power supply filter with a metal cover to enhance the shielding. 4. Protective Cap When the optical module is not in use, cover it with the protective cap. Take particular care with the optical receiving module since, depending on the circuit used, extraneous light may be input to the module when the TOSLINK device is not in use and may adversely affect other circuits. 5. Vibration, Shock and Stress Plastic-molded optical modules are plastic-sealed devices whose wires are fixed with resin. While this structure makes them comparatively resistant to vibration and shock, wire breakage has been observed in equipment in which the soldering and connections are exposed to vibration, shock or stress. Therefore, when using a plastic-molded optical module in equipment with high vibration levels, ensure that the structure is designed to withstand vibration, shock and stress. Ceramic-package optical modules are ceramic-sealed, with a hollow interior. Since the wires in the module are not fixed, the module is susceptible to vibration and shock. Therefore, when using a ceramic-package optical module in equipment which is subject to high levels of vibration and shock, ensure that the structure of the equipment is designed to withstand vibration, shock and stress. 6. Supply Voltage Modules should be used with a supply voltage within the standard operating conditions. Ensure that the supply voltage does not exceed the absolute maximum ratings even momentarily. 7. Input Voltage If a voltage exceeding the absolute maximum rating is applied to the transmitter input, the internal IC may be adversely affected or destroyed. If there is a possibility of excessive input voltage due to a surge, for example, add a protective circuit to the input. 8. Outputt Note that internal ICs can be damaged when the receiver output is low and the output is shorted to the power supply, or when output is high and is shorted to GND. 9. Handling Optical Fiber Cables Do not drop heavy or sharp metal objects onto the optical fiber cable. If the fiber cable breaks, data cannot be transmitted. Also, transmission loss increases with sharp bends in the fiber cable. Toshiba recommends that, if the cable must be bent during installation, the bent section should have as large a radius as possible (six to ten times the minimum bending radius). Some fiber-optic connectors are vertical connectors. When inserting a fiber-optic connector, note the directionality of the connection. When coupling or decoupling a fiber optic connector, be sure to hold the connector itself. Do not detach a fiber-optic connector by pulling on the optical-fiber cord. 10. Assembling Fiber-Optic Connectors Since specialized assembly tools are available for the fiber-optic connectors used with TOSLINK devices, people without specialist knowledge can assemble the connectors. However, the person who assembled the product is responsible for its characteristics and quality. When a connector is to be used in an application where reliability is essential, Toshiba recommends purchasing a pre-assembled product or contacting a specialist with the necessary expertise. 11. Absolute Maximum Ratings The absolute maximum ratings must never be exceeded, even momentarily. Even a single rating value must never be exceeded. The nature of the absolute maximum ratings depend on the product but generally include such parameters as the input and output currents, input voltage, storage temperature, operating temperature and lead temperature. If the input current or voltage exceeds the absolute maximum rating value, overvoltage and overcurrent can adversely affect the internal circuitry of the device. If the rating is grossly exceeded, the wiring may fuse due to heating in the internal circuits, or the circuitry in the semiconductor chips may be destroyed. If, for example, the absolute maximum operating temperature, storage temperature or soldering temperature rating is exceeded, the differences in the coefficients of thermal expansion of the various materials that make up the device can damage the sealing or open up bonded parts. When using TOSLINK devices, never exceed any of the absolute maximum ratings. 12. Recommended Operating Conditions The recommended operating conditions are conditions recommended to ensure the operation described in the individual datasheets. To improve the reliability of a device even further, use the device with a derated maximum voltage, current, temperature or other parameter. Note that the recommended operating conditions are intended to guarantee the stated operation and do not always guarantee characteristic values. 13. Smoke and Fire Since optical modules, connectors and fiber cables are flammable, scorching or burning them may cause them to emit smoke or burst into flame, which can in turn cause gas emissions. Therefore, do not use these devices in the vicinity of flames, smoke or any flammable materials. 14. Disposal Precautions TOSLINK devices and packaging materials must be disposed of by the user as industrial waste products in an environmentally appropriate way and in accordance with the law. 15. Application Precautions While Toshiba strives to improve the quality and reliability of their products, semiconductor products in general can malfunction or break down. When using a Toshiba semiconductor product, it is the purchaser's responsibility to design safe equipment which does not cause loss of life, injury or damage to property. When incorporating a Toshiba device into a product, check the latest product specifications of the Toshiba device and ensure that all parameters remain within the absolute maximum ratings and recommended operating condition ranges. In addition, follow the stipulations in Precautions for Handling Toshiba Semiconductor Products and the Toshiba Semiconductor Reliability Handbook, with regard to the precautions and conditions described in those document.
