> LAN8814 is a low-power, quad-port triple-speed (10BASE-T/100BASETX/1000BASE-T)
> Ethernet physical layer transceiver (PHY). It supports transmission and

> twisted pair (UTP) cables.

> LAN8814 supports industry-standard QSGMII (Quad Serial Gigabit Media

> Independent Interface) providing chip-to-chip connection to four Gigabit
> Ethernet MACs using a single serialized link (differential pair) in each
> direction.

> The LAN8814 SKU supports high-accuracy timestamping functions to
