4.25 Gbps 2:1/1:2 CML Mux/Buffer With Transmit De-Emphasis And Receive Equalization

The DS42MB100 is a Signal Conditioning 2:1 multiplexer and 1:2 fan-out Buffer designed for use in Backplane redundancy or cable driving applications. Signal Conditioning features include input equalization and programmable output de-emphasis that enable data Communication in FR4 Backplane up to 4.25 Gbps. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have four selectable levels of de-emphasis to compensate for transmission losses from long FR4 Backplane or cable attenuation reducing deterministic jitter. The de-emphasis levels CAN be independently controlled for the line-side and switch-side drivers. The internal loopback paths from switch-side input to switch-side output enable at-speed system testing. All receiver inputs and driver outputs are internally terminated with 100& differential terminating resistors.
