The GTY and GTYP receiver provides support for decoding the out-of-band (OOB) sequences described in the Serial ATA (SATA) and Serial Attach SCSI (SAS) specifications and supports beaconing described in the PCI Express specification. GTY and GTYP receiver support for SATA/SAS OOB signaling consists of the analog circuitry required to decode the OOB signal state and state machines to decode bursts of OOB signals for SATA/SAS COM sequences.

The GTY and GTYP receiver also supports beacons that are PCI Express compliant by using interface signals defined in the PHY Interface for the PCI Express (PIPE) Specification. The interconnect logic decodes the beacon sequence.
