product overview marvell ? alaska ? 88E1512 gigabit ethernet (gbe) transceiver is a physical layer device containing a single gigabit ethernet transceiver. the transceiver implements the ethernet physical layer portion of the 1000base-t, 100base-tx, and 10base-t standards. the device supports rgmii (reduced pin count gmii for direct connection) to copper/fiber/ sgmii with auto-media detect, rgmii to copper, rgmii to sgmii/fiber, and sgmii to copper. 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 88E1512 device has an integrated switching voltage regulator to generate all required voltages and can run off a single 3.3v supply; the device supports 1.8v, 2.5v, and 3.3v lvcmos i/o standards. 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 88E1512 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. 10/100/1000 mbps ethernet mac integrated passive termination 88E1512 device rj-45 or m a g mac interface - rgmii serdes/ - sgmii media types: -1000base-t -100base-tx -10base-t fiber optics media types: -1000base-x -100base-fx -sfp fig 1. alaska 88E1512 application application block diagrams marvell alaska 88E1512 integrated 10/100/1000 mbps energy effcient ethernet transceiver 10/100/1000 mbps ethernet mac integrated passive termination 88E1512 device rj-45 m a g n e t i c s mac interface - sgmii media types: -10base-t -100base-tx -1000base-t fig 2. alaska 88E1512 application fiber transceiver 88E1512 device rj-45 t r a n s f o r m e r serdes media type: -1000base-t fig 3. alaska 88E1512 application
