Part Number: AR8031
Function: Ultra low-power 10/100/1000 RGMII/SGMII Gigabit Ethernet Transceiver
Package: 48-pin QFN type
Manufacturer: QUALCOMM, Atheros
The AR8031 is part of the Arctic family of PHYs – which includes the AR8030, AR8033, and AR8031.
This is Qualcomm 4th generation, single port, 10/100/1000 Mbps Ethernet PHY. It supports both RGMII and SGMII interfaces to the MAC. The device provides a low-power, low BOM (bill-of-materials) cost solution for a wide range of applications, including enterprise, carrier and home networks, SFP modules and media converters. This is supports both Sync-E and IEEE1588-V2 timing protcols.
The AR8031 device incorporates a 1.25 GHz SERDES which can be connected directly to fiber-optic transceivers for 1000 Base-X/100 Base-FX mode.
