GENERAL DESCRIPTION

The ADV7671A is a High-Definition Multimedia Interface (HDMI?)

transceiver.

The ADV7671A supports 48 Gbps fixed rate link (FRL) and 18

Gbps transition minimized differential signaling (TMDS) video rates.

The ADV7671A provides an HDMI receiver port, an HDMI transmitter

port, an audio input port, an audio output port, and an enhanced

audio return channel (eARC) interface.

The HDMI receiver and transmitter support up to uncompressed 8k

at 60 Hz (8k60) YCbCr 4:2:0 12-bit video, 8k at 30 Hz (8k30) RGB

12-bit video, and 4k at 120 Hz (4k120) RGB 12-bit high frame rate

video, with Digital Visual Interface (DVI) compatibility.

The audio input and output ports support 8?channel at 192 kHz,

16-Channel at 96 kHz, and 32-Channel at 48 kHz linear pulse

code modulation (LPCM). The ADV7671A audio ports also support

compressed audio formats.

The eARC interface can be configured as either an eARC transmitter

or an eARC receiver. The eARC interface supports 8-channel,

192 kHz LPCM audio, and high bit rate audio (HBR) compressed

audio formats including 1-bit Direct Stream Digital? (DSD) audio,

Dolby Atmos?, Dolby TrueHD?, and DTS-HD?.

The ADV7671A supports passthrough of Display Stream Compression

(DSC) 1.2a data and high dynamic range (HDR) metadata

passthrough for HDMI dynamic HDR, HDR10+, and Dolby Vision?.

The ADV7671A implements the High-bandwidth Digital Content

Protection (HDCP) 2.3 specification to protect the delivery of premium

content. HDCP 2.3 is backward compatible with HDCP 2.2. and

supports HDCP 1.4 to provide interoperability with legacy devices.

The ADV7671A has an integrated on-screen display (OSD) generator

that enables the creation and control of high quality character

and icon-based system status and control displays. The OSD can

be overlaid on uncompressed video formats up to 8k/10k.

The ADV7671A is configured via I2C/serial peripheral interface

(SPI) using a high level host controller application programming

interface (API).

The ADV7671A is provided in a 108-lead lead frame chip scale

package (LFCSP) with exposed pad and is specified over the 0°C

to 70°C temperature range.

To sample or purchase the ADV7671A, customers must be licensed

HDMI 2.1 adopters through HDMI Licensing Administrator, Inc., and

licensed HDCP 2.x adopters through Digital Content Protection, LLC (DCP).
