OVERVIEW
Alaska 88E1545/88E1543/88E1548 Integrated 10/100/1000 Mbps
Energy Efficient Ethernet Transceiver Datasheet
- Public
The latest generation Alaska® Quad family of single-chip devices contains four independent Gigabit Ethernet transceivers on a single monolithic IC. Each transceiver performs all the physical layer functions for 1000BASE-T and 100BASE-TX full or half-duplex Ethernet on CAT 5 twisted pair cable, and 10BASE-T full or half-duplex Ethernet on CAT 3, 4, and 5 cable.
The Alaska 88E1545 device supports the Quad-Serial Gigabit Media Independent Interface (QSGMII) for direct connection to a MAC/Switch port. The QSGMII bines four ports of SGMII running at 1.25 Gbps onto a single differential-pair of signals operating at 5 Gbps. QSGMII primarily decreases the number of I/O pins on the MAC interface pared to the SGMII and lowers the overall power consumption.
The Alaska 88E1543 device supports SGMII on the MAC interface in a Copper to SGMII application. In addition, the...
