A inlocuit cineva un VCXO cu noile produse silicon VCXOs?

Recommended Posts

Nu pot depana,intr-un radio receptor cu sinteza frecventa, un oscilator controlat in tensiune cu cristal quartz 55.301 MHz, defect din cauza quartz-ului, dat fiind practic imposibil sa gasesc in tara sau in lume un cristal de 55.301 MHz.

Internetul recomanda ca solutii: (1) noile rezonatoare MEMS stabile cu orice frecventa de iesire, (2) oscilatoarele quatz cu bucla PLL programabile (dar cu consum mare si jitter la iesire), (3) noile generatii silicon VCXOs setabile pe orice frecventa dintr-un domeniu.

 

Are cineva experienta practica in noile solutii de oscilatoare comerciale stabile pe o anume frecventa?
