product overview marvell ? alaska ? 88E1322 gigabit ethernet (gbe) transceiver is a physical layer device containing 2 gigabit ethernet transceivers. the transceivers implement the ethernet physical layer portion of the 1000base-t, 100base-tx, 10base-t, 1000base-x, and 100base-fx standards. the device supports sgmii (serial gigabit media independent interface for direct connection) to copper/fiber/100base- fx and copper/fiber with auto-media detect. the device also integrates mdi interface termination resistors into the phy. this resistor integration simplifes board layout and reduces board cost by reducing the number of external components. the new marvell calibrated resistor scheme will achieve and exceed the accuracy requirements of the ieee 802.3 return loss specifcations. this device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a gigabit per second data rate. the 88E1322 achieves robust performance in noisy environments with very low power dissipation. the alaska family of transceiver products provides the ideal solution for rapid development and deployment of gigabit standalone and switching systems for the enterprise, embedded, consumer, and metro/service provider market segments. fig 1. alaska 88E1322 application application block diagrams marvell alaska 88E1322 integrated 10/100/1000 mbps energy effcient ethernet transceivers 10/100/1000 mbps ethernet mac integrated passive termination 88E1322 device rj-45 m a g n e t i c s mac interface - rgmii media types: -10base-t -100base-tx -1000base-t fig 2. alaska 88E1322 application 10/100/1000 mbps ethernet mac integrated passive termination 88E1322 device rj-45 m a g n e t i c s mac interface - rgmii media types: -10base-t -100base-tx -1000base-t
