MAX3981

3.125Gbps XAUI Quad Cable Equalizer


Please check latest availability status for a specific part variant.

Description

The MAX3981 quad equalizer provides compensation for transmission medium losses for four "lanes" of digital NRZ data at a data rate of 3.125Gbps in one package. It is tailor-made for 10Gigabit Ethernet applications that require attenuation of noise and jitter that occur in communicating with chassis-to-chassis interconnect. In support of IEEE-802.3ae for the XAUI interface, the MAX3981 adaptively allows XAUI lanes to reach 10m (33ft) with inexpensive twin-axial cable for extended backplane applications.

The equalizer has 100Ω differential CML data inputs and outputs.

The MAX3981 is available in a 44-pin exposed-pad QFN package. The MAX3981 consumes only 700mW at 3.3V or 175mW per channel.
