[18] Measured with an FM deviation of 25 kHz and the typical AF output voltage of 500 mV (RMS). The audio signal processing stage
[19] Amplitude response depends on dimensioning of FM PLL loop filter and components at pin APCLC and pin APCHC.
[20] The lower AF cut-off frequency depends on the value of the capacitor at pin CAF. A value of C
[21] For all signal-to-noise measurements the used VIF modulator has to meet the following specifications:
[22] The PC / SC ratio is calculated as the addition of TV transmitter PC / SC1 ratio and SAW filter PC / SC1 ratio. This PC / SC ratio is
[23] Measurement condition is SC1 / SC2
[24] The differential QSS signal output on pins OUT1A and OUT1B is analyzed by a test demodulator TDA9820. The signal-to-noise ratio of
