The ADV7672 that will be demonstrated by Analog Devices is a HDMI transceiver suitable for home entertainment and professional video applications at 4K 120Hz.
HDMI 2.1 support includes a crosspoint matrix switch, output mirroring, video split, and video merge capabilities. The ADV7672 could be used to extract, process, and route the audio and video to multiple screens or rooms as well as audio and speaker configurations.
The HDMI transceiver supports 40Gbps fixed rate link and 18Gbps transition minimised differential signalling video rates and provides two independent HDMI receiver ports, two independent HDMI transmitter ports, two audio ports, and an enhanced audio return channel (eARC) interface.
Analog Devices says each HDMI receiver and transmitter supports up to 8K video. Each audio port can be independently configured as either an audio extraction or audio insertion port. The audio ports support 8-channel, 192 kHz, 24-bit pulse coded modulation and compressed audio formats including high bitrate formats.
The eARC interface can be configured as either an eARC transmitter or an eARC receiver. The eARC interface supports 8-channel PCM audio and high bit rate audio (HBR) compressed audio formats including Dolby TrueHD and DTS-HD.
The ADV7672 provides a turn-key interface for extracting decrypted HDMI video for processing into an FPGA as well as conversion between HDMI 2.1 and HDM 1.4 formats to enable HDMI 2.1 with minimal product changes.
With the flexible audio interface, audio can be extracted and routed independently of the video to enable mixing down for remote stereo-only displays while also preserving multi-channel audio for decoding and rendering up to the full capabilities of the latest Dolby and DTS object audio formats.
