MSM7663B

GENERAL DESCRIPTION

The MSM7660 is a decoder which converts digitally sampled NTSC or PAL video signals to the format based on ITU-RBT601.
The MSM7660 can accept composite video and S video signals.
For composite signals, the MSM7660 converts signals to YUV data via a 2-dimensional Y/C separation circuit. For S video signals, the MSM7660 converts signals to YUV data by passing the 2-dimensional Y/C separation circuit.
An internal AGC/ACC circuit makes decoding of images relatively easy.
Video signals are internally synchronized, so a relatively wide range of video signals can be decoded without using an external VCO circuit.
