Chrominance Block - Input Signals and Measurement Conditions
Unless otherwise indicated, set up the following conditions for each of the following measurements.
1. VIF and SIF blocks: No signal
2. Deflection block: Input a horizontal and vertical composite synchronizing signal, and assure that the deflection block
is locked to the synchronizing signal. (Refer to the “Deflection Block - Input Signals and Measurement Conditions”
section.)
3. Bus control conditions: All conditions set to the initial conditions unless otherwise specified.
4. Y input: No signal
5. C input: The C1IN input (pin 40) must be used.
6. The following describes the method for calculating the demodulation angle.
B-Y axis angle = tan-1 (B (0)/B (270) + 270°
R-Y axis angle = tan-1 (R (180)/R (90) + 90°
G-Y axis angle = tan-1 (G (270)/G (180) + 180°
7. The following describes the method for calculating the AF angle.
BR ... The ratio between the B-Y and R-Y demodulator outputs.
θ ...... ANGBR: The B-Y/R-Y demodulation angle
R-Y/B-Y
× BR-Cos
θ
AFXXX = tan-1
Sin
θ
8. Attach a TV crystal externally to pin 15.
