3.6. Atheros AR8035 Gigabit LAN
The FLEX-IMX8M-Mini connects the i.MX8M Mini processor RGMII interface to the Atheros AR8035
gigabit Ethernet chip.
The AR8035 supports IEEE 802.3az EEE standard (Energy Efficient Ethernet) and Atheros
proprietary SmartEEE. SmartEEE allows legacy MAC/SoC devices without 802.3az support to
function as a complete 802.3az system.
Features:
•
10/100/1000 BASE-T IEEE 802.3 compliant
•
Supports 1000 BASE-T PCS and auto-negotiation with next page support
•
Supports RGMII and/or SGMII interfaces to MAC devices
•
Supports Fibre and Copper combo mode when MAC interface works in RGMII mode
•
Supports additional IEEE 1000 BASE-X and 100 BASE-FX with Integrated SerDes
•
RGMII timing modes support internal delay and external delay on Rx path
•
Supports Atheros Green ETHOS® power saving modes with internal automatic DSP power
saving scheme
•
Supports IEEE 802.3az (Energy Efficient Ethernet) n Supports SmartEEE which allows MAC/
SoC devices without 802.3az support to function as the complete 802.3az system
•
Fully integrated digital adaptive equalizers, echo cancellers, and Near End Crosstalk (NEXT)
cancellers
•
