The Airoha AN8801R is a low power single-port Ethernet PHY Transceiver
|
|
with Single-port serdes interface for 1000Base-X/RGMII; this chip is
|
|
compliant with 10Base-T, 100Base-TX and 1000Base-T IEEE 802.3(u,ab)
|
|
and supports Energy Efficient Ethernet (802.3az), Full Duplex Control
|
|
Flow (802.3x), auto-negotiation, crossover detect and autocorrection,
|
|
Wake-on-LAN with Magic Packet, and Jumbo Frame up to 9 Kilobytes.
|
|
This PHY also supports up to three user-configurable LEDs, which are
|
|
usually used for LAN Activity, 100M, 1000M indication.
