Description

TA1287PG, TA1287FG are a high-speed switching IC which have 2-channel inputs circuit and a RGB to YUV / IQ matrix circuit. Another feature, TA1287PG, TA1287FG have a signals mixing circuit, which are enable to mix a main signal with an external input signal and outputs the mixed signal. The mixing circuit has 8 combinations of mixing gain ratio of a main to an external signals, which is controlled by high-speed switch.
