Notes:
*
1 Gain is calculated by 20log (Pin 8 level/Pin 1 level).
*
2 Phase difference is difference between input and output phases (given B-Y axis as 0°.)
*
3 Hn output is 1 horizontal output after input signal burst is shifted +45°. Hn
+1
output is 1 horizontal output
after input signal burst is shifted +45°, and that signal is R-Y converted.
*
4 DC step difference is the total of burst sampling step different during PAL conversion and 1H switching
step difference.
1H
*
5 BGP, Hn/Hn + 1 Switching Timing
*
6 This is the smaller of frequency f and horizontal sync signal frequency (fH=15.73khz) difference when the
frequencies are separated sufficiently high and low, then brought closer, and the waveform locks.
*
7 This is the smaller of frequency f and carrier frequency (fC=4.433619MHz) difference when the frequencies
are separated sufficiently high and low, then brought closer, and the waveform locks.
*
8 Carrier leak is the 8.86MHz component level at Pin 12.
