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.
