Input selector switch for high

definition displays

BA7658AFS

The BA7658AFS is an IC designed for high definition displays, and has an internal selector circuit for broadband

RGB signals and HD / VD signals, a synchronization separator circuit, and a NUTEK signal detector circuit. This IC

chip simplifies the configuration of input blocks for high-end displays.

•Applications

CRT displays, HDTV, video board for personal computer, etc.

•Features

1) Operates on a single 5V power supply.

2) Internal broadband RGB selector with a frequency

characteristic of 230MHz ( – 3dB)

3) Internal HD / VD selector.

4) Internal separator for synchronization signal super-

imposed on the G signal.

5) Internal detector for NUTEK power saving signals.

•Absolute maximum ratings (Ta = 25°C)
