The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the
internal video signal with 1.1 V (p-p) as a reference:

i(PC)
V
and
where:
is the correction term for RMS value,
is the sound-to-picture carrier ratio at pins VIF1 and VIF2
in dB, 6 dB is the correction term of internal circuitry and
±
3 dB is the tolerance of video output and intercarrier output
V
o(intc)(rms)
.
Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from
the tuning system.
