DESCRIPTION
The SN65LVCP408 is a 8 × 8 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 8:1
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 SN65LVCP408 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 SN65LVCP408 is characterized for operation
from –40°C to 85°C. (See operating free air condition requirements)
