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.

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

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.
