DEVICE OPERATION
INPUT INTERFACING
The DS30BA101 accepts either differential or single-ended input. DC-coupled inputs must be kept within the
specified common-mode range.
OUTPUT INTERFACING
The DS30BA101 uses current mode outputs. Single-ended output levels are 800 mVP-P into 75ΩAC-coupled
coaxial cable with an RVO resistor of 750Ω, or 400 mVP-P (800 mVP-P differential) into 100Ωdifferential cable with
an RVO resistor of 953Ω. The output voltage level is controlled by the value of the RVO resistor connected
between the RVO pin and VCC.
The RVO resistor should be placed as close as possible to the RVO pin. In addition, the copper in the plane layers
below the RVO network should be removed to minimize parasitic capacitance.
Figure 2 and Figure 3 show the typical configurations for differential output and single-ended output, respectively.
For single-ended output, the unused output must be properly terminated as shown.
APPLICATION INFORMATION
CABLE EXTENDER APPLICATION
The DS30BA101 together with the DS30EA101 form a cable extender chipset optimized for extending serial data
streams from serializer/deseralizer (SerDes) pairs and FPGAs over 100Ωdifferential cables and 75Ωcoaxial
cables. Setting the correct DS30BA101 output amplitude and proper cable termination are essential for optimal
operation. Figure 2 shows the recommended chipset configuration for 100Ωdifferential cable and Figure 3 shows
the recommended chipset configuration for 75Ωcoaxial cable.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based
flame retardants must also meet the <=1000ppm threshold requirement.
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation
of the previous line and the two combined represent the entire Device Marking for that device.
(6) Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
