The DS42MB200isa dual signal conditioning 2:1 1– 4.25 Gbps Fully Differential Data Paths multiplexer and 1:2 fan-out buffer designed for usein• Fixed Input Equalization backplane redundancy applications. Signal Programmable Output Pre-emphasis conditioning features include input equalization and
programmable output pre-emphasis that enable data• Independent Switch and Line Side Pre- communicationin FR4 backplanes upto 4.25 Gbps.emphasis Controls Each input stage hasa fixed equalizerto reduce ISI• Programmable Switch-side Loopback Mode distortion from board traces. On-chip Terminations All output drivers have4 selectable steps of pre-• +3.3V Dupply emphasisto compensate for transmission losses from ESD Rating HBM6 kV long FR4 backplanes and reduce deterministic jitter.
The pre-emphasis levels can be independently• Lead-less WQFN-48 Package controlled for the line-side and switch-side drivers.(7mmx7mmx0.8mm, 0.5mm Pitch) The internal loopback paths from switch-side inputto• –40°Cto +85°C Operating Temperature Range switch-side output enable at-speed system testing.All
receiver inputs are internally terminated with 100ΩAPPLICATIONS differential terminating resistors. All driver outputs are
