product overview marvell? alaska? 88e1548/48p 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, in full compliance with the 802.3 standards. on the mac-side interface, the device supports quad-serial gigabit media interface (qsgmii) to copper or fiber, quad- port sgmii to copper, or dual-port sgmii to fiber. the 88E1548P version supports the marvell linkcrypt? feature, which is based on and implements the ieee802.1ae macsec protocol. this version also supports precise timing protocol (ptp) time stamping, which is based on ieee 1588v2 and ieee 802.1as, in both two-step and single-step clock operation. in addition to supporting energy efcient ethernet (eee) on the new generation of enabled macs, these products are also capable of implementing eee with legacy or non-eee devices by incorporating eee bufering. the device 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 device achieves robust performance in noisy environments with very low power dissipation. the 88e1548/48p integrates an advanced virtual cable tester? (vct?) enabling fault detection and advanced cable performance monitoring. 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. marvell alaska 88e1548/48p quad port 10/100/1000 mbps ethernet transceivers with qsgmii or sgmii interfaces quad 10/100/1000 mbps ethernet mac with qsgmii interface 88e1548 rj-45 rj-45 rj-45 rj-45 m a g n e t i c s system interface - qsgmii media interface: -10base-t -100base-tx -1000base-t fig 1. marvell alaska 88e1548 in a qsgmii to copper application block diagram transceivers
