FEATURES
DESCRIPTION
The PLL500-20 is a low cost, high performance and
low phase noise VCXO for the 20 to 52MHz range,
providing less than -130dBc at 10kHz offset at
52MHz. The very low jitter (4 ps RMS period jitter)
makes this chip ideal for applications requiring volt-
age controlled frequency sources. Input crystal can
range from 20 to 52MHz (fundamental resonant
mode).
