To adjust contrast, two types of controls are provided, main and sub. With the main control, the contrast of the 3-channels can be changed simultaneously. Sub controls are used to adjust the contrast of a given channel individually. The control terminals can be controlled by applying a voltage of 0 to 5V. The DC power remains stable at the IC output terminal because a feedback circuit is built in. M52734SP OSD BLK IN 130MHz. The circuit also features the OSD mixing function.
