Power Save
LA73024AV has two supplies 5V for Video part and 12V for audio part and FSS output. LA73024AV separates
perfectly 5V system from 12V system, so it can be individually movement. For example when in the stand-by mode, if
you open 14 pins but 5V supplies 24 and 29 pins, Video part and serial control part work normally. In this case audio
part and FSS output don’t work normally. And when you pull up 8pin and open 24 pin , IC chooses automatically video
sw3-B.Consequently Ext input and Decoder output only move , you can save more power dissipation .
Audio Mute
LA73024AV builds in two mute transistors for reduce audio pop-noise when occur at power on and off. You can
control both on serial control and on external parallel control for audio mute.
