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 pre-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 Pre-emphasis to compensate for transmission losses from long FR4 backplane or cable attenuation reducing deterministic jitter. The Pre-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 are internally terminated with 100? differential terminating resistors. All driver outputs are internally terminated with 50? terminating resistors to VCC.
