TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA1287PG,TA1287FG
RGB TO YUV / IQ HIGH-SPEED MATRIX IC
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.
