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/–6dB, then is input to the YS circuit. The CXA2119M also has one RGB signal input system (R, G, B IN: Pins 9 to 11). This RGB signal (specified input level: 100 IRE, 0.7Vp-p) is input to the IC via a capacitor, and is matrix converted to a YCbCr signal from the RGB signal. The conversion formula is: Y = 0.299R + 0.587G + 0.114B Cb = 0.564 (– 0.299R – 0.587G + 0.886B) Cr = 0.713 (0.701R – 0.587G – 0.114B) Then, the converted YCbCr signal passes the 6dB amplifier, and the capacitors connected to Y, Cb and Cr CLP (Pins 12 to 14) are used to clamp it, and it is input to the YS circuit. The Y1Cb1Cr1/Y2Cb2Cr2 signal or the Y1Cb1Cr signal converted from RGB input is selected by YS (Pin 20) control. The selected signal is output to Y, Cb and Cr OUT (Pins 16 to 18). Signal pedestal level at output is approximately 3.8V. The CXA2119M has three inputs for composite video signal input (SIG1, SIG2, SIG3 IN: Pins 24, 26, 28). These signals (specified input level: 1Vp-p (including sync)) are input to the IC via capacitors, and the signal selected by SEL1 (Pin 25) and SEL2 (Pin 27) control is output via the 6dB amplifier from SIG OUT (Pin 22).
