DESCRIPTION
The ABV0017 is a low cost, high performance and
low phase noise VCXO for the 17 to 36MHz range,
providing less than -130dBc at 10kHz offset at
35.328MHz. The very low jitter (2.5 ps RMS period
jitter) makes this chip ideal for applications requiring
voltage controlled frequency sources. Input crystal
can range from 17 to 36MHz (fundamental resonant
mode).
