PL502-03
DESCRIPTION
The PL502-03 is a low cost, high performance and low phase noise VCXO for the 48 to 100MHz range, providing less than -130d Bc at 10k Hz offset at 48MHz. The very low jitter (3.5ps RMS period jitter) makes this chip ideal for applications requiring voltage controlled frequency sources. Input crystal can range from 12 to 25MHz (fundamental resonant mode).
