(Two channels use serial input.) It uses both a matrix cell and weighted current technology to achieve both low power consumption and high speed. It features built-in output resistor, reference resistor, and low pass filter, and provides independent output amplitude adjustment for the Y (luminance) and C (chroma) synchronization signals. The Y (luminance signal) can be superimposed with an external SYNC signal. Pin Assignment N.C. VOUT VCC UOUT AVSS VCC YOUT AVSS VREFY N.C. COMPY VREFS DY4 DY3 DY2 DY1 SYNC VCC DVSS N.C. N.C.
