Complete SCART Solution Dramatically Reduces Power Consumption in Set-Top Boxes and A/V Receivers

Maxim introduces the MAX9597, the industry's integrated, +3.3V SCART solution for set-top boxes and A/V receivers that have one SCART connector. Designed to enable greener consumer applications, this device utilizes innovative, power-saving technology to dramatically reduce power consumption.

Designed to enable greener consumer applications, this device utilizes innovative, power-saving technology to dramatically reduce power consumption. Maxim's patented DirectDrive technology enables the device to operate audio and video signals from +3.3V, thereby eliminating the need for a +5V supply and minimizing the use of a +12V supply. This low-voltage operation, combined with the MAX9597's miserly 53mW quiescent current consumption, makes it much easier to meet stringent energy-efficiency requirements for set-top boxes.

Functional Overview

The  MAX9597 eases the routing of audio and video signals between an MPEG encoder and an external SCART connector. It integrates standard-definition video filters on all video-encoder inputs, and all audio drivers deliver a full-scale (2.0VRMS, min) output. The audio section contains left and right audio paths with an independent operational amplifier at the inputs. The MAX9597 is controlled through an I²C-compatible interface.
