FEATURES
DESCRIPTION
The DS64EV400 programmable quad equalizer
2
• Equalizes up to 24 dB Loss at 10 Gbps
provides compensation for transmission medium
• Equalizes up to 22 dB Loss at 6.4 Gbps
losses and reduces the medium-induced deterministic
• 8 Levels of Programmable Equalization
jitter for four NRZ data channels. The DS64EV400 is
optimized for operation up to 10 Gbps for both cables
• Settable through Control Pins or SMBus
and FR4 traces. Each equalizer channel has eight
Tnterface
levels of input equalization that can be programmed
• Operates up to 10 Gbps with 30” FR4 Traces
by three control pins, or individually through a Serial
• Operates up to 6.4 Gbps with 40” FR4 Traces
Management Bus (SMBus) interface.
• 0.175 UI Residual Deterministic Jitter at 6.4
The equalizer supports both AC and DC-coupled data
Gbps with 40” FR4 Traces
paths for long run length data patterns such as
PRBS-31, and balanced codes such as 8b/10b. The
• Single 2.5V or 3.3V Power Supply
device uses differential current-mode logic (CML)
• Signal Detect for Individual Channels
inputs and outputs. The DS64EV400 is available in a
• Standby Mode for Individual Channels
7 mm x 7 mm 48-pin leadless WQFN package.
• Supports AC or DC-Coupling with Wide Input
Power is supplied from either a 2.5V or 3.3V supply.
Common-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 Range
