DS40MB200 Dual 4-Gbps 2:1/1:2 CML MUX/Buffer With Transmit Pre-Emphasis
Receive Equalization Features 3 DescriptionThe DS40MB200 deviceisa dual signal conditioning 1-Gbpsto 4-Gbps Low Jitter Operation 2:1 multiplexer (MUX) and 1:2 fan-out buffer designed• Fixed Input Equalization for usein backplane-redundancy applications. Signal• Programmable Output Pre-Emphasis conditioning features include continuous time linear
equalization (CTLE) and programmable output pre-• Independent Switch and Line Side Pre-Emphasis emphasis, extending data communication in FR4Controls backplanesat rates upto4 Gbps. Each input stage• Programmable Switch-Side Loopback Mode has a fixed equalizer to reduce intersymbol• On-Chip Terminations interference distortion from board traces. 3.3-V Supply All output drivers have four selectable stepsof pre-• ESD Ratingof 6-kV HBM emphasisto compensate for transmission losses from
long FR4 backplanes and reduce deterministic jitter.• 48-leadless WQFN Package(7 mm×7 mm) The pre-emphasis levels can be independently• 0°Cto +85°C Operating Temperature Range controlled for the line-side and switch-side drivers.
