1 / 6 page 1 Multimedia ICs Video signal switcher, 1 × 3-channel with clamped-input BA7653AF The BA7653AF is a video-signal switching IC that contains a three-channel clamped-input multiplexer. 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, television and camcorders •Features 1) Small clamp capacitors can be used (ceramic, 3000pF (Min.), 0.01 µF (FS) (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 (70nsec. Typ.). 4) Low power consumption (when VCC = 5V, 25mW Typ.). 5) Wide dynamic range (3.1VP-P Typ. for VCC = 5V). 6) Excellent frequency characteristics (10MHz, 0dB Typ.). 7) Low interchannel crosstalk ( – 70dB Typ.). 8) Voltage can be applied to the control pins even when VCC is not applied. •Absolute maximum ratings (Ta = 25°C) Parameter Symbol Limits Unit VCC 9V mW Topr °C Tstg °C 500∗ Pd – 25 ~ + 75 – 55 ~ + 125 Applied voltage Power dissipation Operating temperature Storage temperature ∗ When mounted on a 50mm × 50mm board, reduced by 5mW for each increase in Ta of 1°C over 25°C. •Recommended operating conditions (Ta = 25°C) Parameter Symbol Limits Unit VCC V 4.0 ~ 7.0 Power supply voltage |
