EP9472

EP9472 is a 6 GHz HDMI 2.1 4-IN 2-OUT Matrix with HDCP. The chip supports 4 inputs to 2 outputs matrix switching with HDCP repeater function. The chip also supports HDCP 1.4 to HDCP 2.3 and HDCP 2.3 to HDCP 1.4 conversions. The chip supports Audio Outputs in IIS and SPDIF. The audio for the HDMI output can be from a regenerated LPCM audio source (input from IIS_*_IN pins), eARC RX, ARC RX or the by-passed audio from the selected HDMI input port. The chip supports SD/HD Audio and HD/3D/4K2K Video up to 60 Hz frame rate. The chip also supports eARC (enhanced Audio Return Channel) and ARC (Audio Return Channel) Receiver.

This chip supports the SPDIF to IIS conversion to reduce system cost.
