The PL500-37 is a low cost, high performance and
low phase noise VCXO for the 36 to 130MHz range,
providing less than -148dBc at 10kHz offset at
77.76MHz. The very low jitter (2.5 ps RMS period
jitter) makes this chip ideal for applications requiring
voltage controlled frequency sources. The input
crystal frequency can range from 36 to 130MHz
(fundamental resonant mode). ^: Denotes internal Pull-up 32 mil 8 …
