Low-Power Audio/Video Switches With Audio Volume Control For Dual SCART Connectors

The MAX9670 MAX9671 dual SCART matrices route Audio and Video signals between a set-top box decoder chip and two external SCART connectors under I²C control. Operating from a 3.3V supply and a 12V supply, the MAX9670 MAX9671 consume 70mW during quiescent operation and 471mW during average operation when driving typical signals into typical loads. Video input detection, Video load detection, and a 2.5mW standby mode facilitate the design of intelligent, low-power set-top boxes. By Maxim Integrated Products
