Input equalization and programmable output preemphasis support data rates up to 4 Gbps. mon applications are redundancy switching, signal buffering, or performance improvements on legacy backplane hardware. The SN65LVCP40 bines 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 pensate for transmission line losses. The receivers incorporates receive equalization and pensates for input transmission line loss. This minimizes deterministic jitter in the link. The equalization is optimized to pensate for a FR-4 backplane trace with 5-d B, high-frequency loss between 375 MHz and 1.875 GHz. This corresponds to a 24-inch long FR-4 trace with 6-mil...
