DS64EV400-EVK DESCRIPTION

The DS64EV400 programmable quad equalizerprovides compensation fortransmission mediumlosses and reduces the medium-induced deterministicjitter for four NRZ data channels. The DS64EV400 isoptimized for operation up to 10 Gbps for both cablesand FR4 traces. Each equalizer channel has eightlevels of input equalization that can be programmedby three control pins, or individually through a SerialManagement Bus (SMBus) interface.The equalizer supports both AC and DC-coupled datapaths forlong run length data patterns such asPRBS-31, and balanced codes such as 8b/10b. Thedevice uses differential current-mode logic (CML)inputs and outputs. The DS64EV400 is available in a7 mm x 7 mm 48-pin leadless WQFN package.Power is supplied from either a 2.5V or 3.3V supply. • Equalizes up to 22 dB Loss at 6.4 Gbps8 Levels of Programmable Equalization • • Settable through Control Pins or SMBusTnterface • Operates up to 10 Gbps with 30” FR4 Traces • Operates up to 6.4 Gbps with 40” FR4 Traces0.175 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 InputCommon-Mode • Low Power Consumption: 375 mW Typ at 2.5V • Small 7 mm x 7 mm 48-Pin WQFN Package • •9 kV HBM ESD Rating-40 to 85°C Operating Temperature RangeSimplified Application Diagram
