Hi
Can you tell us the detail about these register?
Q1) IN_LOCK
Are the following conditions for locking in the case of NTSC?
Horizontal sync signal (Hsync): Specified frequency ± 5% (Example: NTSC: 15.73kHz ± 5%)
Vertical sync signal (Vsync): 40-70Hz
Synchronized signal amplitude: 20% -200% (100% = 300mV @ PAL or 286mV @ NTSC)
Q2) LOST_LOCK
Do you recognize that LOST_LOCK will be performed when IN_LOCK is released?
Q3) FSC_LOCK
Are the following conditions for locking in the case of NTSC?
Burst signal frequency: Specified frequency ± 1.3kHz (Example: NTSC: 3.5795MHz ± 1.3kHz)
Burst signal amplitude: 5% -200% (100% = 300mV @ PAL or 286mV @ NTSC)
Q4) INST_HLOCK
Couldn't understood what this register doing.
Under what conditions do you lock?
Best regards
Kawa
