6. Chroma input signal:
As for the PAL signal, the burst swings such as 130° and 225° every one hour.
Chroma describes the phase caused when the burst occurs at 135°.
As for the NTSC signal, the burst occurs constantly at 180°.
The figures below are based on the phase of NTSC. When a PAL signal is generated, adjust the phase and then enter
signals.
The item common to both PAL and NTSC is the PAL signal. For those other than this, the measurement must be
performed for each individual signals.
The condition of fsc: Set the following conditions unless otherwise specified.
PAL = 4.433619MHz
NTSC = 3.579545MHz
