MAX9597
Low-Power Audio/Video Interface for Single SCART Connectors
Industry's First Integrated, 3.3V, Single SCART Solution for Set-Top Box and DVD Applications
|
Status
Active: In Production.
Description
The MAX9597 single SCART interface routes audio and video signals between a set-top box decoder chip and an external SCART connector under I²C control. Operating from a 3.3V supply and a 12V supply, the MAX9597 consumes 53mW during quiescent operation and 254mW during average operation when driving typical signals into typical loads.
The MAX9597 audio section contains left and right audio paths with an independent operational amplifier at the inputs. The DirectDrive® output amplifiers create a 2VRMS full-scale audio signal biased around ground, eliminating the need for bulky output capacitors and reducing click-and-pop noise. The zero-cross detection circuitry also further reduces clicks and pops by enabling audio sources to switch only during a zero-crossing.
The MAX9597 video section contains 4 channels of video filter amplifiers. The standard-definition video signals from the set-top box decoder chip are lowpass filtered to remove out-of-bandwidth artifacts. The MAX9597 also supports slow-switching and fast-switching signals.
The MAX9597 is available in a compact 28-pin thin QFN package and is specified over the 0°C to +70°C commercial temperature range.
