Origin Oscillation Check (NTSC (60i) & PAL
(50i) modes) (VC-367 board)
Check the frequency of the clock for synchronization.
If deviated, the synchronization will be disrupted and the color will
become inconsistent.
Note1:
Origin oscillation frequency:
80.9090MHz ...... NTSC mode
80.1000MHz ...... PAL mode

Checking method in NTSC (60i) mode:
1)
Set the NTSC (60i)/PAL (50i) switch to “NTSC (60i)”.
2)
Check that the frequency (f) satisfies the NTSC specified value.
Checking method in PAL (50i) mode:
1)
Set the NTSC (60i)/PAL (50i) switch to “PAL (50i)”.
2)
Check that the frequency (f) satisfies the PAL specified value.
