www.ti.com SNLS281H – AUGUST 2007 – REVISED APRIL 2013 DS64EV400 Programmable Quad Equalizer
Check for Samples: DS64EV400 FEATURES 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. 1 2 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
Tnterface
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
