Serial ATA 3.0 (except FIS-based switching)

–

AHCI Revision 1.3 (except FIS-based switching)

–

AMBA 3 AXI interfaces

●

User-defined PHY status and control ports

●

RX data buffer for recovered clock systems

●

Data alignment circuitry when RX data buffer is also included

●

OOB signaling detection and generation

●

8b/10b encoding/decoding

●

Asynchronous signal recovery, including retry polling

●

Digital support of device hot-plugging

●

Power management features including automatic partial-to-slumber transition

●

BIST loopback modes

●

Single SATA device

●

Internal DMA engine per port

●

Hardware-assisted native command queuing for up to 32 entries
