DESCRIPTION
The SN65LVCP204 is a 4×4 non-blocking crosspoint
switch in a flow-through pinout that allows for ease in
PCB layout. VML signaling is used to achieve a
high-speed data throughput while using low power.
Each of the output drivers includes a 4:1 multiplexer
to allow any input to be routed to any output. Internal
signal paths are fully differential to achieve high
signaling speeds while maintaining low signal skews.
The SN65LVCP204 incorporates 100-Ω termination
resistors for those applications where board space is
at a premium. Transmit preemphasis and receive
equalization are built in for superior signal integrity
performance.

    ... The SN65LVCP204 built-in passive input equalizer compensates for ISI. For a 25-inch (63,5-cm) FR4 transmission line with 8-mil (0,2-mm) trace width, the SN65LVCP204 typically reduces jitter from the device input to the device output.

    ... Each SN65LVCP204 receiver input incorporates an equalizer and compensates for such frequency loss. The SN65LVCP204 equalizer provides frequency gain between 375 MHz and 1.875 GHz, compensating roughly for 20 inches (50,8 cm) of FR4 material with 8-mil (0,2-mm) trace width. Distortion jitter improvement is substantial, often providing more than 30-ps jitter reduction ...
