... PLL feedback divider ratio. LO Source Many applications require a stable RF source. For this purpose, the TH71071 can be used without modulation as an easy-to-use, PLL-stabilized, continuous wave (CW) generator. Frequency Modulation (FM) For FM operation an external varactor is required. It simply acts as a pulling capacitor connected in series to the crystal ...
