Q1: U ka Lekola Thermistor ee-E lefelletseng LVPECL Oscillator?
A: 1) Netefatsa ho nepahala ha maqhubu a tlhahiso le botsitso (± ppm) holim'a mefuta eohle ea mocheso.
2) Lekanya phapang e fapaneng ea tlhahiso ea waveform botšepehi (amplitude, nako ea ho phahama / ho oa) tlas'a mojaro.
3) Netefatsa -mesebetsi ea maemo a mararo; haeba ho se na tlhahiso, hlahloba Enolla leeme la phini le lerata la phepelo ea motlakase.
Q2: Mathata a Tloaelehileng le Litharollo tsa Oscillator Ena
A: Taba ea 1: Phase Jitter e Feteletseng kapa E sa hloekang ea Output Waveform
Lebaka: Pheliso e sa nepahalang ea phapang, lerata le fetelletseng la phepelo ea motlakase, kapa sebopeho se fosahetseng sa PCB.
Lokisa: Netefatsa hore 50Ω e bapelang ho Vcc-2V e behiloe haufi le moamoheli. Ntlafatsa ho kopanya matla ka li-capacitor tse tlase tsa ESL. Lipara tse fapaneng tsa litsela tse nang le impedance e laoloang.
Taba ea 2: Frequency Output ha e Fosahetse kapa Drifts Beyond Spec
Sesosa: Ho hloleha ha potoloho ea matšeliso ka hare, ntho e senyehileng ea kristale, kapa ho sebetsa ka ntle ho maemo a boletsoeng.
Lokisa: Fetola yuniti. Netefatsa hore motlakase o kenang le mojaro li ka har'a litekanyetso tse phahameng ka ho fetesisa le maemo a khothaletsoang a ts'ebetso.
