GENERAL DESCRIPTION
The ML86V7667 is an LSI that converts NTSC and PAL analog video signals into the standard digital format or
8-bit digital data conforming to ITU-R recommendation BT.601/BT.656 YCbCr.
The video input has a built in 1-channel 10-bit A/D converter and supports composite video signals.
The composite video signal is separated into luminance and chrominance signals by an adaptive 2-dimensional
Y/C separation filter (2- or 3-line adaptive comb filter) and converted into general purpose video data format.
The sampling methods that can be used are the asynchronous sampling method which is a feature of Oki’s
decoders and the line-locked clock sampling method using a digital PLL.
As for image jitter, which is a problem in asynchronous sampling methods in normal cases, jitter-free output data
can be obtained because the ML86V7667 incorporates into it a pixel position correction circuit and a FIFO for
pixel count correction.
USES AND APPLICATION EXAMPLES
The ML86V7667 can be used as a video signal input interface IC in any system carrying out digital image
processing. It can be operated using digital PLL with line-locked clock in applications requiring high picture
quality. Also, high-speed synchronous operation using asynchronous clock is possible in applications requiring
high-speed synchronization, such as switching operation using multichannel inputs.
