Marvell 88Q1010 100BASE-T1 PHY

88Q1010 - 100Mbps IEEE 802.3bw compliant Automotive Ethernet PHY

The Marvell® 88Q1010 solution is a single pair Ethernet physical layer transceiver (PHY) which implements the Ethernet physical layer portion of the 100BASE-T1 standard as defi ned by the IEEE 802.3bw task force. Ideally suited for a wide range of automotive applications, it is manufactured using a standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on a single balanced twisted pair.

88Q1010 integrates media dependent interface (MDI) termination resistors into the PHY which simplifi es the board layout and reduces board cost by reducing the number of external components. It has an integrated linear voltage regulator to generate all required voltages so the device can run off a single 3.3V supply. The solution supports 1.8V, 2.5V, and 3.3V LVCMOS I/O standards.

In addition, 88Q1010 uses advanced mixed-signal processing to perform equalization, echo, data recovery, and error correction at a 100Mbps data rate to achieve robust performance and exceed automotive electromagnetic interference (EMI) requirements in noisy environments with very low power dissipation.

Finally, 88Q1010 is compatible to the footprint of the 88Q2110 100/1000BASE-T1 Ethernet PHY transceiver to ensure an upward path to 1Gbps designs.
