General Description

The MAX3980 quad equalizer provides compensation for transmission medium losses for four “lanes” of digital NRZ data at a 3.125Gbps data rate in one package. It is tailor-made for 10-Gigabit Ethernet (10GbE) back plane applications requiring attenuation of noise and jitter that occur in communicating from MAC to PMD or from MAC to Switch. In support of the IEEE-802.3ae for the XAUI interface, the MAX3980 adaptively allows XAUI lanes to reach up to 40in (1.0m) on FR-4 board material.
