Features • 2:1 multiplexer and 1:2 buffer • 0.25–2.5 Gbps fully differential data paths • Fixed input equalization • Programmable output Pre-emphasis • Independent Pre-emphasis controls • Programmable loopback modes • On-chip terminations • HBM ESD rating 6 kV on all pins • +3.3V supply • Low power, 0.45 W typical • Lead-less LLP-36 package • −40°C to +85°C operating temperature range Description The DS25MB100 is a signal conditioning 2:1 multiplexer and 1:2 fan-out buffer designed for use in backplane redundancy or cable driving applications. Signal conditioning features include input equalization and programmable output Pre-emphasis that enable data communication in FR4 backplane up to 2.5 Gbps. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. All output drivers have four selectable levels of Pre-emphasis to compensate for transmission losses from long FR4 backplane or cable attenuation reducing 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 internally terminated with 50Ω to VCC. Applications • Backplane or cable driver • Redundancy and signal conditioning applications • CPRI/OBSAI

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
