说明

The SN65LVCP40 is a signal conditioner and data multiplexer optimized for backplanes. Input equalization and programmable output preemphasis support data rates up to 4 Gbps. Common applications are redundancy switching, signal buffering, or performance improvements on legacy backplane hardware.

The SN65LVCP40 combines a pair of 1:2 buffers with a pair of 2:1 multiplexers (mux). Selectable switch-side loopback supports system testing. System interconnects and serial backplane applications of up to 4 Gbps are supported. Each of the two independent channels consists of a transmitter with a fan-out of two, and a receiver with a 2:1 input multiplexer.

The drivers provide four selectable levels of preemphasis to compensate for transmission line losses.
