Industry’s Lowest Power Automotive Ethernet PHY

Second generation 88Q1110/88Q1111 100BASE-T1

Marvell Industry’s Lowest Power Automotive Ethernet PHY - 88Q1110/88Q1111 100BASE-T1

88Q111x

88Q111x implements the Ethernet physical layer portion of the 100BASE-T1 standard as defined by the IEEE 802.3bw task force.  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.  The 88Q1111 device supports Serial GMII (SGMII) for direct connection to a MAC or switch port. SGMII operates at 1.25 Gbps over a single differential pair, reducing power and number of I/Os used on the MAC interface.

The device integrates media dependent interface (MDI) termination resistors into the PHY. This resistor integration simplifies board layout and reduces board cost by reducing the number of external components.

The device has an integrated linear voltage regulator to generate all required voltages. The device can run off a single 3.3V supply.

The device achieves robust performance and exceeds automotive electromagnetic interference (EMI) requirements in noisy environments with very low power dissipation. This device is compatible to the footprint of Marvell 88Q1010 100BASE-T1 and 88Q2110 100/1000BASE-T1 Ethernet PHY transceivers.
