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. 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 (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 monitorin...
