product overview marvell ? alaska ? 88E1543 gigabit ethernet transceiver is a physical layer device containing four independent gigabit ethernet transceivers. each transceiver performs all the physical layer functions for 1000base-t, 100base-tx and 10base-t standards. the device supports quad serial gigabit media independent interface (sgmii) to copper and dual-port sgmii (system) to copper/fiber/sgmii with auto-media detect. in addition to supporting energy effcient ethernet (eee) on the new gener ation of enabled macs, these products are also capable of implementing eee with legacy or non-eee devices by incorporating eee buffering. 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. the alaska 88E1543 device has an integrated switching voltage regulator to generate all required voltages and can run off of a single 3.3v supply. 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 device achieves robust performance in noisy environments with very low power dissipation. the marvell 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. 10/100/1000 mbps ethernet mac 10/100/1000 mbps ethernet mac 10/100/1000 mbps ethernet mac 10/100/1000 mbps ethernet mac 88E1543 devices rj-45 rj-45 rj-45 rj-45 m a g n e t i c s system interface: - sgmii media interface: -10base-t -100base-tx -1000base-t fig 1. sgmii to copper application application block diagram marvell alaska 88E1543 quad port 10/100/1000 mbps energy effcient ethernet transceiver dual 10/100/1000 mbps ethernet mac with sgmii interface 88E1543 devices sfp interface (x2) rj-45 (x2) m a g (x2) system interface: - sgmii media interface: -1000base-t -100base-tx -10base-t media interface: -sgmii (media) -1000base-x -100base-fx fig 2. dual-port sgmii (system) to copper/sgmii/fiber with automedia
