BA7657F Datasheet, PDF (1/13 Pages) Rohm – Input selector switch for high definition displays

Multimedia ICs
Input selector switch for high
definition displays
BA7657F / BA7657S
The BA7657F and BA7657S are for high definition displays, and have internal switches for switching between broad-
band RGB signals and HD / VD signals, as well as an internal synchronization separator. These ICs simplify the de-
signing of input units for deluxe displays.
•^Applications
CRT display, HDTV, video board for personal computer, etc.
•^Features
1) Operates on a single 5V power supply.
2) Internal broadband RGB switch (frequency charac-
teristics: 230MHz, – 3dB).
3) Internal HD / VD switch.
4) Internal synchronization separator for synchronizing
signals superimposed onto G signals.
