DS42MB200 Dual 4.25 Gbps 2:1/1:2 CML Mux/Buffer with Transmit Pre-Emphasis and

Receive Equalization

Check for Samples: DS42MB200

FEATURES

DESCRIPTION

The DS42MB200 is a dual signal conditioning 2:1

multiplexer and 1:2 fan-out buffer designed for use in

•

1– 4.25 Gbps Fully Differential Data Paths

Fixed Input Equalization

•

backplane

redundancy

applications.

Signal

Programmable Output Pre-emphasis

conditioning features include input equalization and

programmable output pre-emphasis that enable data

communication in FR4 backplanes up to 4.25 Gbps.

Each input stage has a fixed equalizer to reduce ISI

distortion from board traces.

Independent Switch and Line Side Pre-

emphasis Controls

•

Programmable Switch-side Loopback Mode

On-chip Terminations

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 switch-side input to

switch-side output enable at-speed system testing. All

receiver inputs are internally terminated with 100Ω

differential terminating resistors. All driver outputs are

+3.3V Dupply

ESD Rating HBM 6 kV

Lead-less WQFN-48 Package
