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 0.01
µF (FZ) ceramic].
Applications
Video cassette recorders and camcorders
Features
1) Small clamp capacitors can be used (ceramic,
3000pF (Min.), 0.01
µF (FZ) (recommended)).
2) Low supply voltage operation possible. Supply volt-
age 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 VCC = 5V, 25mW Typ.).
5) Wide dynamic range (3.1VP-P Typ. for VCC = 5V).
6) Mute function.
7) Excellent frequency characteristics
(10MHz, 0dB Typ.).
8) Low interchannel crosstalk ( – 70dB Typ.).
9) Voltage can be applied to the control pins even
when VCC is not applied.
