GENERAL DESCRIPTION
The ADV7671 is a High-Definition Multimedia Interface (HDMI®)
transceiver.
The ADV7671 supports 48 Gbps fixed rate link (FRL) and 18 Gbps
transition minimized differential signaling (TMDS) video rates. The
ADV7671 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 output port supports 8‑channel, 192 kHz linear pulse
code modulation (LPCM), and the audio input port supports
2-channel, 192 kHz LPCM. The ADV7671 audio ports also support
compressed audio formats.
The eARC interface supports 8-channel, 192 kHz PCM 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™. Audio return channel (ARC) is also
supported on the eARC interface.
The ADV7671 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 ADV7671 also supports variable refresh rate (VRR), fast Vactive
(FVA), and automatic low latency mode (ALLM) passthrough
mode for HDMI.
The ADV7671 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 backward compatible with HDCP 2.2.
The ADV7671 is configured via I2C using a high level host controller
application programming interface (API).
The ADV7671 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 ADV7671, 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).
