Multimedia ICs Video signal swither, 1 × 3-channel with clamped-input BA7652AF The BA7652AF is a video-signal switching IC that contains a three-channel clamped-input multiplexer and a built-in mute circuit.
The inputs are sync-tip clamped (synchronous edge of the video input signals are aligned to the same voltage), and as the input impedance is extremely large, it is possible to use a small value for the clamp capacitor.
[The recommended capacitor is 0.01µF (FZ) ceramic].
Applications
BA7652AF Features
* 1) Small clamp capacitors can be used (ceramic, 3000pF (Min.), 0.01µF (FZ) (recommended)). 2) Low supply voltage operation possible. Supply voltage range is 3.7V to 7.7V. 3) Superimposition used for fast switching speed with low switching noise (70ns. Typ.). 4) Low power consumption (when
