Every time CDTO is set, the internal subcarrier
DTO phase is reset to 0 and the RTCO output
generates a logic 0 at time slot 68 (see
document “RTC Functional Description” ,
available on request). So an identical subcarrier
phase can be generated by an external device
(e.g. an encoder); if a DTO reset is programmed
via CDTO it has always to be executed in the
following order:
50 Hz/625 lines: PAL BGDHI (4.43 MHz)
60 Hz/525 lines: NTSC M (3.58 MHz)
50 Hz/625 lines: NTSC 4.43 (50 Hz)
60 Hz/525 lines: PAL 4.43 (60 Hz)
50 Hz/625 lines: combination-PAL N (3.58 MHz)
60 Hz/525 lines: NTSC 4.43 (60 Hz)
50 Hz/625 lines: NTSC N (3.58 MHz)
