88Q211x 100/1000BASE-T1 PHY
Marvell® 88Q2110/88Q2112 solutions are single pair Ethernet physical layer transceivers (PHYs) that implement the Ethernet physical layer portion of the 100/1000BASE-T1 standard as defined by the IEEE 802.3bw and IEEE 802.3bp standard. Ideally suited for a wide range of automotive applications, they are manufactured using a standard digital CMOS process and contain all the active circuitry required to implement the physical layer functions to transmit and receive data on a single balanced twisted pair.
88Q2110/88Q2112 integrates media dependent interface (MDI) termination resistors into the PHY which simplifies the board layout and reduces board cost by reducing the number of external components. Also, they support an integrated linear voltage regulator to generate all required voltages so the device can run off a single 3.3V supply. Both solutions support 1.8V, 2.5V, and 3.3V LVCMOS I/O standards.
