6. 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:

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

Vo(intc)(rms).

7. 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.
