sound carrier traps (see
Measurement using unified weighting filter (“ ITU-T J.61” ), 200 kHz high-pass filter, 5 MHz low-pass filter and subcarrier notch filter
(“ ITU-T J.64” ).
The intercarrier output signal at pin SIOMAD can be calculated by the following formulae taking into account the internal video signal
with 1.1 V (p-p) as a reference:
the correction term for RMS value,
term of internal circuitry and 3 dB is the tolerance of video output and intercarrier output V
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.
