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. www.DataSheet4U.com 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. The MSM7664 is an improved version of the MSM7662, and is particularly superior in the picture 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.
