GENERAL DESCRIPTION

The ADV7672 is a High-Definition Multimedia Interface

(HDMI®) transceiver with crosspoint matrix switch, video

mirror, video split, and video merge capabilities.

The ADV7672 supports 40 Gbps fixed rate link (FRL) and 18 Gbps

transition minimized differential signaling (TMDS) 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.

Each HDMI receiver and transmitter supports 8k30 RGB/YCbCr

4:4:4 10-bit video, 8k60 YCbCr 4:2:0 10-bit high definition

video, and 4k120 4:4:4 10-bit high frame rate 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 (PCM) 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 192 kHz PCM audio and high bit rate audio (HBR)

compressed audio formats including Dolby TrueHD™ and

DTS-HD™. Audio return channel (ARC) is also supported on

the eARC interface.

The ADV7672 supports display stream compression (DSC)

1.2a data passthrough and high dynamic range (HDR)

metadata passthrough for HDMI dynamic HDR, HDR10+, and

Dolby Vision™.

The ADV7672 implements the High-bandwidth Digital

Content Protection (HDCP) 2.3 specification to protect the

delivery of premium content. HDCP 2.3 is applied in

transmitter, receiver, and repeater configurations. HDCP 2.3 is

backwards compatible with HDCP 2.2. HDCP 1.4 is also

supported to provide interoperability with legacy devices.

controller interface (API).

The ADV7672 is provided in a 108-lead, lead frame chip scale

package (LFCSP) with an exposed paddle and is specified over a

0°C to 70°C temperature range.

Customers that wish to sample or purchase the ADV7672 must

be licensed HDMI 2.1 adopters listed at HDMI.org and licensed

HDCP 2.x adopters listed at Digital-CP.com.
