M61280M8-xxxFP
KillP hue remaining with killer
1. Input SG.E (level: -40 dB) to pin 26.
2. Measure the pin 33 output amplitude.
APCU APC pull-in range (upper)
APCL APC pull-in range (lower)
1. Input SG.E (feb-fec-3.579545 MHz) to pin 26.
2. After raising the frequency until the output from pin 33 vanishes, lower the frequency, and take the point at which
an output appears to be fu.
3. After lowering the frequency until the output from pin 33 vanishes, raise the frequency, and take the point at which
an output appears to be fl.
4. APCU and APCL are defined as follows.
APCU = fu – 3579545 Hz
APCL = fl – 3579545 Hz
R/BN demodulation ratio R-Y/B-Y
1. Input SG.E (eb = single chroma = ec + 50 kHz) to pin 26.
2. Take the pin 33 output amplitude when "test mode" I²C data is 1DH D6 = 1, D7 = 1 to be VRY.
3. Take the pin 33 output amplitude when "test mode" I²C data is 1DH D6 = 0, D7 = 1 to be VBY.
4. R/BN is defined as follows.
R-YN demodulation angle
1. Input SG.E (eb = single chroma = ec + 5 kHz) to pin 26.
2. Take the pin 33 output amplitude when "test mode" I²C data is 1DH D6 = 1, D7 = 1 to be VRY.
3. Take the pin 33 output amplitude when "test mode" I²C data is 1DH D6 = 0, D7 = 1 to be VBY.
4. R/YN is defined as follows.
* The vector is determined taking the demodulator gain into account.
