Features Equalizes up to 24 dB loss at 10 Gbps Equalizes up to 22 dB loss at 6.4 Gbps 8 levels of programmable equalization Settable through control pins or SMBus interface Operates up to 10 Gbps with 30” FR4 traces Operates up to 6.4 Gbps with 40” FR4 traces 0.175 UI residual deterministic jitter at 6.4 Gbps with 40” FR4 traces Single 2.5V or 3.3V power supply Signal Detect for individual channels Standby mode for individual channels Supports AC or DC-Coupling with wide input common-mode Low power consumption: 375 mW Typ at 2.5V Small 7 mm x 7 mm 48-pin LLP package 9 kV HBM ESD Rating -40 to 85°C operating temperature range Description The DS64EV400 programmable quad equalizer provides compensation for transmission medium losses and reduces the medium-induced deterministic jitter for four NRZ data channels. The DS64EV400 is optimized for operation up to 10 Gbps for both cables and FR4 traces. Each equalizer channel has eight levels of input equalization that can be programmed by three control pins, or individually through a Serial Management Bus (SMBus) interface. The equalizer supports both AC and DC-coupled data paths for long run length data patterns such as PRBS-31, and balanced codes such as 8b/10b. The device uses differential current-mode logic (CML) inputs and outputs. The DS64EV400 is available in a 7 mm x 7 mm 48-pin leadless LLP package. Power is supplied from either a 2.5V or 3.3V supply.

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.
