Gigabit 2 × 2 CROSSPOINT SWITCH
DESCRIPTION
The SN65LVCP202 is a 2 × 2 nonblocking crosspoint
switch in a flow-through pinout allowing 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 2:1 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 SN65LVCP202 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 SN65LVCP202 is characterized for operation
from –40°C to 85°C.

    ... The SN65LVCP202 built-in passive input equalizer compensates for ISI. For a 20-inch (50,8-cm) FR4 transmission line with 8-mil (0,2-mm) trace width, the SN65LVCP202 typically reduces jitter from the device input to the device output.

    ... Differential Figure 8. AC Test Circuit — Jitter and Output Rise Time Test Circuit The SN65LVCP202 input equalizer provides 5-dB frequency gain to compensate for the frequency loss of a shorter backplane transmission line. For characterization purposes, a 24-inch (61-cm) FR-4 coupled transmission line is used in place of the backplane trace. The 24-inch (61-cm) trace provides roughly attenuation between 375 MHz and 1 ...

    ... This frequency dependent loss causes distortion jitter on the transmitted signal. Each SN65LVCP202 receiver input incorporates an equalizer and compensates for such frequency loss. The SN65LVCP202 equalizer provides frequency gain between 375 MHz and 1.875 GHz, compensating roughly for 20 inches of FR4 material with 8-mil (0,2-cm) trace width. Distortion jitter improvement is substantial, often providing more than 30-ps jitter reduction ...
