DS42MB100 - 4.25 Gbps 2:1/1:2 CML Mux/Buffer

General Description

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.

Key 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 lo.
