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 resistor integration simplifies 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 specifications.

The device has an integrated switching voltage regulator to generate all required voltages. The device can run off a single 3.3V supply. The device supports 1.8V, 2.5V, and 3.3V LVCMOS I/O Standards.

The 88E1510/88E1518/88E1512/88E1514 device supports Synchronous Ethernet (SyncE) and Precise Timing Protocol (PTP) Time Stamping, which is based on IEEE1588 version 2 and IEEE802.1AS.

The 88E1510/88E1518/88E1512/88E1514 device supports IEEE 802.3az-2010 Energy Efficient Ethernet (EEE) and is IEEE 802.3az-2010 compliant.

The device incorporates the Marvell Advanced Virtual Cable Tester® (VCT™) feature, which uses Time Domain Reflectometry (TDR) technology for the remote identification of potential cable malfunctions, thus reducing equipment returns and service calls. Using VCT, the Alaska device detects and reports potential cabling issues such as pair swaps, pair polarity and excessive pair skew. The device will also detect cable opens, shorts or any impedance mismatch in the cable and reporting accurately within one meter the distance to the fault.

The device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a Gigabits per second data rate. The device achieves robust performance in noisy environments with very low power dissipation.
