General Description
AK8850 General Description
The AK8850 decodes NTSC composite video, S-Video and Component Video signals (525/625) into digital formats. Digital output conforms to ITU-R BT.601 and ITU-R BT.656* YCrCb specifications. The AK8850 outputs a control signal to generate clocks synchronized with either Horizontal Sync or Vertical Sync signals. Its clock rate is 27 MHz.
An encoded VBID Closed Caption signal can be extracted from the video signal and sent to an external pin on the AK8850.
