Electronic viewfinder driver

BA7149F

The BA7149F is an electronic viewfinder driver for video cameras. It separates the synchronous signal from the input

video signal, and outputs the vertical deflection drive output and horizontal deflection signals. HD and VD output sig-

nals with guaranteed phase difference are also provided for on-screen displays (OSD). The differences between the

BA7149F and the BA7148F are the horizontal blanking, horizontal AFC output, HD output phase and pulse width.
