GENERAL DESCRIPTION

The MSM7664 is an LSI device that decodes NTSC or PAL analog video signals into YCbCr and RGB digital data based on ITU-RBT.601.

The device has built-in two channels of A/D converters and can accept composite video and S video signals for the input video signals. Composite video signals are converted to YCbCr and RGB digital data via the 2-dimensional Y/C separation circuit with an adaptive filter.

APPLICATION EXAMPLES

Since the synchronization of input signals and high-speed locking for color burst are possible, the device is optimized for applications used by switching multiple cameras.

It is also used for various image processing applications because of jitter-free output data through a built-in FIFO buffer.

Even in the PAL mode, a YC separation characteristics equivalent to the NTSC mode has been achieved thereby making this LSI ideally suitable for PAL mode applications.

8-bit (YCbCr), 16-bit (8-bit (Y) + 8-bit (CbCr)), and 24-bit (RGB) output interfaces can be selected as an output mode so that various devices such as monitoring system, digital video memory, digital TV, video processing unit and video communication unit can be selected on the receiving side.
