3.125Gbps XAUI Quad Cable Equalizer

MAX3981

General Description

Features

The MAX3981 quad equalizer provides compensation

for transmission medium losses for four “lanes” of digi-

tal NRZ data at a data rate of 3.125Gbps in one

package. It is tailor-made for 10Gigabit Ethernet appli-

cations that require attenuation of noise and jitter that

occur in communicating with chassis-to-chassis inter-

connect. In support of IEEE-802.3ae for the XAUI inter-

face, the MAX3981 adaptively allows XAUI lanes to

reach 10m (33ft) with inexpensive twin-axial cable for

extended backplane applications.

♦ Four Differential Digital Data “Lanes” at

3.125Gbps

♦ Span 10m (33ft) of Twin-Axial Cable

♦ Receiver Equalization Reduces Intersymbol

Interference (ISI)

♦ Low Power, 175mW per Channel

♦ Standby Mode—Power-Down State

♦ Single 3.3V Supply

The equalizer has 100Ω differential CML data inputs

and outputs.

♦ Signal Detect

The MAX3981 is available in a 44-pin exposed-pad

QFN package. The MAX3981 consumes only 700mW at

3.3V or 175mW per channel.
