MSM7664  
NTSC/PAL Digital Video Decoder  
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.  
Analog video signals can be sampled by a clock at the pixel frequency or at twice the pixel  
frequency. A decimation filter is built-in for sampling at twice the pixel frequency.  
Input signals are synchronized internally and high-speed locking for color burst is possible.  
Because a FIFO buffer is built into the output format circuit, jitter-free output can be obtained  
even for non-standard signals.  
TheMSM7664isanimprovedversionoftheMSM7662, andisparticularlysuperiorinthepicture  
quality and stabilization of synchronization in the PAL decoder as well as the stabilization of  
synchronization in the decoder under weak electric fields.  
Further, although a part of the registers have been added, the electrical characteristics of both  
products are almost identical and their pin compatibility makes it possible to use the MSM7664  
instead of the MSM7662.  
APPLICATION EXAMPLES  
Sincethesynchronizationofinputsignalsandhigh-speedlockingforcolorburstarepossible,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.
