ML86V7668 pdf datasheet (NTSC/

The ML86V7668 is an LSI that converts NTSC, PAL and SECAM analog video signals into the YCbCr standard digital format defined by ITU-R recommendations BT.601/BT.656 and RGB digital data. The device has two built-in 10-bit A/D converter channels and can accept composite video or S-video signal as input. The composite video signal is separated into a luminance signal and chrominance signals by a 2-dimensional Y/C separation filter (2-line or 3-line adaptive comb filter) and are then converted to a general-purpose video data format. In addition to the asynchronous sampling that is a special feature of Oki decoders, video signals can also be sampled using digital PLL for line lock clock sampling. Further, due to the built-in pixel position correction circuit and the FIFO for correcting the pixel count, the video jitter that can be a problem with asynchronous sampling is eliminated and jitter-free output data is ensured.
