MSM7654 NTSC/PAL Digital Video Encoder

The MSM7654, which is a digital video encoder supporting NTSC/PAL formats, converts digital image data to an analog video signal. The encoder can receive the digital image or RGB digital image signals conforming to ITU-R BT.601 as an input signal. The encoder can output simultaneously the composite video and S-video signals, and it can also www.DataSheet4U.c.
