DESCRIPTION
The SN65LVCP404 is a 4x4 non-blocking crosspoint
switch in a flow-through pin-out 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 4:1 multiplexer
to allow any input to be routed to any output. Internal
signal paths are fully differential to achieve the high
signaling speeds while maintaining low signal skews.
The SN65LVCP404 incorporates 100-Ω termination
resistors for those applications where board space is
a premium. Built-in transmit pre-emphasis and
receive equalization for superior signal integrity
performance.
The SN65LVCP404 is characterized for operation
from -40°C to 85°C.
