MN673794
Overview
This IC is used to process a variety of items including the following ones: NTSC/PAL signal (Y/C and posite video) I/O, 3D Y/C separation, TBC, DD conversion, frame sync, sync/clock generation, Rec 656 I/O.
- Features
- Analog input block posite video/ponent Y input (10 bits at 27.0 MHz) ponent C input (10 bits at 27.0 MHz)
- Analog control block AGC (Auto Gain Control), clamp control, ACC (Auto Color Control)
- Digital I/O block Digital video I/O (ITU-R Rec 656: Y/Cr/Cb multiple, 8 bits at 27 MHz) Digital video input clock must be synchronized with the system clock of 27 MHz.
- Signal processing block 3D Y/C separation (image movement adaptive processing: NTSC), 2D Y/C separation (PAL) TBC (Time Base Corrector) processing (velocity error correction/jitter correction) Frame sync processing (See Note.) NR processing (Y/C recursive NR) Y/C separation is performed only in two dimensions (due to memory sharing) when the NR function is in use.
