The HDMI Rx PHY is the physical layer of an HDMI receiver. The HDMI Rx PHY implements the analog front-end (AFE) of an HDMI receiver, the sampling and deserialization of the three data streams, and the digital circuitry for TMDS decoding and operating mode management, providing a digital interface to the link controller. The HDMI Rx PHY integrates auto-calibrated input termination resistors and automatic adaptive line equalization for long cable support. An additional clock receiver is included for reference system clock reception.
