88E1518
OVERVIEW
The Alaska® 88E1510/88E1518/88E1512/88E1514 device is a physical layer device containing a single 10/100/1000 Gigabit Ethernet transceiver. The transceiver implements the Ethernet physical layer portion of the 1000BASE-T, 100BASE-TX, and 10BASE-T standards. It is manufactured using standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair.
The device supports the RGMII (Reduced pin count GMII) and SGMII for direct connection to a MAC/Switch port. The SGMII can also be used on media/line side to connect to SFP modules that support 1000BASE-X, 100BASE-FX and SGMII. It also supports Copper/Fiber Auto-media applications with RGMII as the MAC interface. SGMII operates at 1.25 Gbps over a single differential pair thus reducing power and number of I/Os used on the MAC interface.
The device integrates MDI termination resistors into the PHY. This...
