5 V mixer/oscillator and synthesizer for PAL and NTSC standards
[1]
The RF frequency range is dened by the oscillator frequency range and the Intermediate Frequency (IF).
[2]
This is the level of the RF unwanted signal, 50 % amplitude modulated with 1 kHz, that causes a 1.1 kHz FM modulation of the local
oscillator and thus of the wanted signal; Vwanted = 100 dBV; funwanted =fwanted + 5.5 MHz. The FM modulation is measured at the
oscillator output with a peeking coil using a modulation analyzer with a peak-to-peak detector and a post detection lter of
300 Hz up to 3 kHz.
[3]
Channel SO2 beat is the interfering product of fRFpix, fIF and fosc of channel SO2; fbeat = 37.35 MHz. The possible mechanisms are:
fosc 2 × fIF or 2 × fRFpix fosc. For the measurement Vo(IFOUT) =VRFpix = 115 dBV.
