88EA1512 10/100/1000BASE-T PHY

Marvell® 88EA1512 Gigabit Ethernet Transceivers are physical layer devices 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 transceiver is qualified for automotive applications and is fully AECQ100 qualified. The part supports a wide range of automotive applications, including when 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 connection is required.

The 88EA1512 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 88EA1512 achieves robust performance in noisy environments with very low power dissipation.
