Core Overview - 2.2 English

The Video PHY Controller core is a feature-rich soft IP core that incorporates all the necessary logic to properly interface with media access control (MAC) layers and perform physical-side interface (PHY) functionality. AMD IP cores have been successfully tested on hardware and verified. For additional details on the interoperability results, contact your local AMD sales representative.

The PHY is intended to simplify the use of serial transceivers and adds domain-specific configurability. The Video PHY Controller IP is not intended to be used as a standalone IP and must be used with AMD Video MACs, such as the HDMI™ 1.4/2.0 Transmitter/Receiver Subsystems and DisplayPort TX/RX Subsystems . The core enables simpler connectivity between MAC layers for TX and RX paths. However, it is still important to understand the behavior, use, and limitations of the transceivers. For more information, see UltraScale Architecture GTH Transceivers User Guide (UG576) and UltraScale Architecture GTY Transceivers User Guide (UG578).

The following figure shows the standard OSI Model and mapping it with video IP solutions.

In accordance with the OSI model, the major PHY component for video IP cores is SerDes. Standardizing the SerDes delivery model provides benefits and flexibility for a video MAC layer at the system level.
