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 transmit-
ter 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.
► On-chip, 4-block EDID SRAM managed by external MCU host
processor through API
► HDMI transmitter
► Up to 48 Gbps FRL support

icons on 2D and 3D video formats
► CEC 1.4 and 2.0
► HDMI 1.4a, HDMI 1.4b, HDMI 2.0, and HDMI 2.1 compliant, and
DVI-compatible transceiver
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.
