D[19:0] Databus
As mentioned previously, in Serializer mode D[19:0] is configured as a input. In Deserializer mode,
D[19:0] is configured as an output.
Application Information
The VSC6511 cable driver output is intended to fully comply with the SMPTE-292M cable driver specifi-
cations. This includes an 800mV swing and a return loss of more than 15dB. The circuit shown below shows
how to connect the output of the VSC6511 to the 75 ohm cable and downstream device. The output of the
VSC6511 is actually 1200mV. The output termination circuit shown below attenuates the output signal to
800mV and ensures a return loss better than -15dB. The ISET resistor is 1.78K
