The USB protocol controller works with no software code, but the USB descriptors can be modified in some areas (for example, vendor ID/product ID). The PCM2901/2903 employs SpActTM architecture, TI's unique system that recovers the audio clock from USB packet data. On-chip analog PLLs with SpAct enable playback and record with low clock jitter and with independent playback and record sampling rates. 1 2 3 4 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

Copyright (c) 2002-2007, Texas Instruments Incorporated PCM2901 PCM2903 www.ti.com SLES034C - MARCH 2002 - REVISED NOVEMBER 2007 This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Alternative setting #0 is the only possible setting for interface #0. Alternative setting #0 describes the standard audio control interface. A terminal constructs the audio control interface. The PCM2901/2903 has the following five terminals. * Input terminal (IT #1) for isochronous-out stream * Output terminal (OT #2) for audio analog output * Feature unit (FU #3) for DAC digital attenuator * Input terminal (IT #4) for audio analog input * Output terminal (OT #5) for isochronous-in stream Input terminal #1 is defined as USB stream (terminal type 0x0101). Input terminal #1 can accept 2-channel audio streams constructed by left and right channels. Output terminal #2 is defined as a speaker (terminal type 0x0301). Input terminal #4 is defined as microphone (terminal type 0x0201). Output terminal #5 is defined as a USB stream (terminal type 0x0101). Output terminal #5 can generate 2-channel audio streams constructed by left and right channels. Feature unit #3 supports the following sound control features. * Volume control * Mute control The built-in digital volume controller can be manipulated by an audio class specific request from 0 dB to -64 dB in 1-dB steps. Changes are made by incrementing or decrementing by one step (1 dB) for every 1/fS time interval until the volume level has reached the requested value. Each channel can be set for different values. The master volume control is not supported. A request to the master volume is stalled and ignored. The built-in digital mute controller can be manipulated by audio class-specific request. A master mute control request is acceptable. A request to an individual channel is stalled and ignored. Interface #1 Interface #1 is defined as the audio streaming data-out interface. Interface #1 has the following seven alternative settings. Alternative setting #0 is the zero-bandwidth setting.

Alternative setting #0 is the only possible setting for interface #3. Interface #3 constructs the HID consumer control device. Interface #3 reports the following three key statuses. * Mute (0xE209) * Volume up (0xE909) * Volume down (0xEA09) End-Points The PCM2901/2903 has the following four end-points. * Control end-point (EP #0) * Isochronous-out audio data stream end-point (EP #2) * Isochronous-in audio data stream end-point (EP #4) * HID end-point (EP #5) The control end-point is a default end-point. The control end-point is used to control all functions of the PCM2901/2903 by the standard USB request and USB audio-class-specific request from the host. The isochronous-out audio data stream end-point is an audio sink end-point, which receives the PCM audio data. The isochronous-out audio data stream end-point accepts the adaptive transfer mode. The isochronous-in audio data stream end-point is an audio source end-point, which transmits the PCM audio data. The isochronous-in audio data stream end-point uses asynchronous transfer mode. The HID end-point is an interrupt-in end-point. HID end-point reports HID0, HID1, and HID2 pin status every 32 ms. The human interface device (HID) pins are defined as consumer control devices. The HID function is designed as an independent end-point from both isochronous-in and -out end-points. This means that the device affected by the HID operation depends on the host software. Typically, the HID function affects the primary audio-out device.

The 12-MHz crystal resonator must be connected to XTI (pin 21) and XTO (pin 20) with one high (1-M) resistor and two small capacitors, the capacitance of which depends on the load capacitance of the crystal resonator. If the external clock is used, the clock must be supplied to XTI, and XTO must be open. The PCM2901/2903 has an internal power-on reset circuit, which works automatically when VDD (pin 27) exceeds 2.5 V typical (2.7 V to 2.2 V), and about 700 s is required until internal reset release.) Digital Audio Interface (PCM2903) The PCM2903 employs both S/PDIF input and output. Isochronous-out data from the host is encoded to the S/PDIF output and the DAC analog output. Input data is selected as either S/PDIF or ADC analog input. When the device detects an S/PDIF input and successfully locks on the received data, the isochronous-in transfer data source is automatically selected from S/PDIF itself; otherwise, the data source is selected to ADC analog input. Supported Input Data (PCM2903) The following data formats are accepted by the S/PDIF input and output. All other data formats are unable to use S/PDIF. * 48-kHz 16-bit stereo * 44.1-kHz 16-bit stereo * 32-kHz 16-bit stereo Mismatch between input data format and host command may cause unexpected results except in the following conditions. * Record monaural format from stereo data input at the same data rate * Record 8-bit format from 16-bit data input at the same data rate A combination of the foregoing conditions is not accepted. For playback, all possible data-rate source is converted to 16-bit stereo format at the same source data rate. Channel Status Information (PCM2903) The channel status information is fixed as consumer application, PCM mode, copyright, and digital/digital converter. All other bits are fixed as 0s except for the sample frequency, which is set automatically according to the data received through the USB. Copyright Management (PCM2903) Isochronous-in data is affected by the serial copy management system (SCMS). Where receiving digital audio data that is indicated as original data in the control bit, input digital audio data transfers to the host. If the data is indicated as first generation or higher, transferred data is selected to analog input. Digital audio data output is always encoded as original with SCMS control. The implementation of this feature is an option for the customer. Note that it is the user's responsibility whether they implement this feature in their product or not. INTERFACE SEQUENCE Power On, Attach, and Playback Sequence The PCM2901/2903 is ready for setup when the reset sequence has finished and the USB bus is attached. In order to perform certain reset sequences defined in the USB specification, VDD, VCCC, VCCP1, VCCP2, and VCCX must rise up with 10 ms / 3.3 V. After connection has been established by setup, the PCM2901/2903 is ready to accept USB audio data. While waiting, the audio data (idle state) and analog output are set to bipolar zero (BPZ). When receiving the audio data, the PCM2901/2903 stores the first audio packet, which contained 1-ms audio data, into the internal storage buffer. The PCM2901/2903 starts playing the audio data when detecting the following start of frame (SOF) packet. 24 Submit Documentation Feedback Copyright (c) 2002-2007, Texas Instruments Incorporated Product Folder Link(s): PCM2901 PCM2903 PCM2901 PCM2903 www.ti.com SLES034C - MARCH 2002 - REVISED NOVEMBER 2007 3.3 V (Typ) VDD (Pin 27) 2.5 V (Typ) 0V 5 V = VBUS (Typ) SEL1 (Pin 9) Bus Reset st 1 Audio Data Set Configuration 2 nd Audio Data Bus Idle D+/D- SOF SOF SOF SSPND BPZ VOUTL VOUTR 700 ms Device Setup 1 ms Internal Reset Ready for Setup Ready for Playback Attach (Connect to USB Bus) T0055-03 Figure 35.

All products are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI's standard warranty.

Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices.

TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
