描述 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- 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.
