... Description of Operation The CXA2119M has two input systems for the YCbCr signal (Y1, Cb1, Cr1 IN: Pins Y2, Cb2, Cr2 IN: Pins 5 to 7). These two signals (specified input level: 100% color bar, 0.7Vp-p) are input via capacitors, and are clamped to approximately 4V at the timing of the CLP pulse input to CLP (Pin 8). After clamping, they pass the 6dB amplifier, and one system is selected by INPUT SEL (Pin 4) control. The selected YCbCr signal is controlled by YM (Pin 21) for 0/– ...
