DS25MB200 Dual 2.5 Gbps 2:1/1:2 CML Mux/Buffer with Transmit PreEmphasis and Receive Equalization
General Description
The DS25MB200 is a dual signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy applications. Signal conditioning features include input equalization and programmable output pre-emphasis that enable data communication in FR4 backplanes up to 2.5 Gbps. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have 4 selectable steps www.DataSheet4U.com of pre-emphasis to compensate for transmission losses from long FR4 backplanes and reduce deterministic jitter.
