PEDL7662-02 PEDL7662-02 This version: Oct. 1999 MSM7662 Previous version : Oct. 1998 el Pr y ar in im ¡ Semiconductor MSM7662 ¡ Semiconductor NTSC/PAL Digital Video Decoder GENERAL DESCRIPTION The MSM7662 is an LSI device that decodes NTSC or PAL analog video signals into YCb Cr and RGB digital data based on ITU-RBT.601. The device has built-in two channels of A/D converters and can accept posite video and S video signals for the input video signals. posite video signals are converted to YCb Cr 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. 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. 8-bit (YCb Cr), 16-bit (8-bit (Y) + 8-bit (Cb Cr)), 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 munication unit can be selected on the receiving side. Features (- new feature not found on MSM7661B) - Input analog signal NTSC/PAL posite video signal or S-video signal - Maximum 5 posite or 2 S-video + 2 posite analog inputs can be connected (switchable by external pins or internal registers) - Built-in clamp circuits and video amps - Built-in 8-bit A/D converters (2 channels) - 4 selectable output...
