DS40MB200 - Dual 4 Gb/s 1:2 Mux/Buffer

General Description

The DS40MB200 is a dual signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy applications.

Key Features

  • include input equalization and programmable output preemphasis that enable data communication in FR4 backplanes up to 4 Gb/s. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have 4 selectable steps of pre-emphasis to compensate for transmission losses from long FR4 backplanes and reduce deterministic jitter. The pre-emphasis levels can be independently controlled for the line-side and switch-side drivers. The internal loopback paths from swit.
