资 源 简 介
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.
