Overview
The ADV7622BSTZ-RL, produced by Analog Devices Inc., is a high-performance, four-input, one-output High-Definition Multimedia Interface (HDMI) transceiver. This integrated circuit combines HDMI receiver and transmitter functions along with digital audio inputs and outputs on a single chip. It supports all mandatory HDMI 3D TV formats, as well as all HDTV formats up to 1080p and 36-bit Deep Color. The ADV7622 also integrates an HDMI CEC (Consumer Electronics Control) controller and supports capability, discovery, and control (CDC) features. Fabricated in an advanced CMOS process, it is packaged in a 144-lead, 20 mm × 20 mm, Pb-free LQFP and operates over a temperature range of 0°C to 70°C.
