Product Details

The ADV7674 is a High-Definition Multimedia Interface (HDMI®) transceiver.

The ADV7674 supports 48 Gbps fixed rate link (FRL) and 18 Gbps transition minimized differential signaling (TMDS) video rates and provides four independent HDMI receiver ports, an HDMI transmitter port, an audio input port, an audio output port, four enhanced audio return channel (eARC) outputs, and eARC receiver. InstaPort™ ultrahigh definition (UHD) fast switching is supported between each HDMI receiver input.

The ADV7674 features an EZ Audio 1:4 eARC/ARC switch. The audio input port and audio output port each support 8‑channel, 192 kHz linear pulse code modulation (LPCM) and compressed audio formats.

The ADV7674 eARC/ARC transmitters and receiver support 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 ADV7674 also supports variable refresh rate (VRR), fast Vactive (FVA), and automatic low latency mode (ALLM) passthrough mode for HDMI.

The ADV7674 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 ADV7674 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, and is backward compatible with HDCP 2.2.

The ADV7674 is configured via I2C using a high level host controller application programming interface (API).

The ADV7674 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 ADV7674, 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).
