With the digitally tuned picture carrier oscillator
(DTO_PC), the IF frequency for the picture carrier
demodulation can be set. This function is
implemented for general purpose applications which
are different from nominal TV standards. It can also
be used for debugging purposes. The DTO_PC is
part of the picture carrier PLL. To set the DTO_PC
value to a certain PC input frequency (fIF), please
use the following formula:
. If e.g. the IF
picture carrier input frequency is 5.75 MHz
(M/N standard), one gets 92 F685h as result for
DTO_PC.

The DTO_SC is part of the FM/AM mono sound
demodulator. DTO_SC is calculated according to the
following formula, whereas fSC is the sound carrier
frequency:
.
In case of M/N standard (sound carrier at 4.5 MHz),
one gets 55 5555h for DTO_SC.
