Physical layer (PHY) controller
Atheros Communications
* High-performance cost-down solution
The Atheros INT6400/INT1400 HomePlug AV chipset solution is comprised of the INT6400 Medium Access Controller (MAC)/Physical layer (PHY) IC and the INT1400 AFE/Line Driver IC. The Atheros HomePlug AV transceiver is optimized for multi-media streaming applications and is fully compliant with the HomePlug AV standard to reliably deliver up to 200 Mbps PHY rate over powerline wiring.
In addition to the complete MAC and PHY, the INT6400 includes an Ethernet Media Independent Interface (MII) and an external Synchronous Dynamic Random Access Memory (SDRAM) interface. In addition, the INT6400 includes the Analog-to-Digital (A/D) and Digital-to-Analog (D/A) converters required for analog interface to the INT1400 AFE/Line Driver IC. The INT1400 AFE/Line Driver IC includes a Tx filter, a programmable-gain line driver and a programmable-gain Rx amplifier. The programmability of these amplifiers opens up new and important signal optimization functionality.
