Features • 250 Mbps – 2.5 Gbps low jitter operation • Optional Fixed Input Equalization • Selectable Output De-emphasis • Individual Loopback Controls • On-chip Termination • +3.3V supply • Lead-less eLLP-60 pin package • (9mmx9mmx0.8mm, 0.5mm pitch) • −40°C to +85°C Industrial Temperature Range • 6 kV ESD Rating, HBM Description The DS25BR400 is a quad 250 Mbps – 2.5 Gbps CML transceiver, or 8-channel buffer, for use in backplane and cable applications. With operation down to 250 Mbps, the DS25BR400 can be used in applications requiring both low and high frequency data rates. Each input stage has a fixed equalizer to reduce ISI distortion from board traces. The equalizers are enabled through two control pins. These control pins provide flexibility in applications where ISI distortion may vary from one direction to another. All output drivers have four selectable steps of de-emphasis to compensate for transmission loss. The de-emphasis blocks are also grouped in fours. In addition, the DS25BR400 also has loopback control capability on four channels. All the CML drivers have 50Ω termination to Vcc. All receivers are internally terminated with differential 100Ω. Applications • Backplane or cable driver • Signal buffering and repeating

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.
