FEATURES
DESCRIPTIONS
The PLL502-01 is a low cost, high performance and
low phase noise VCXO, providing less than -130dBc
at 10kHz offset in the 24MHz to 50MHz operating
range. The very low jitter (10 ps RMS period jitter)
makes this chip ideal for applications requiring volt-
age controlled frequency sources. Input crystal can
range from 12 to 25MHz (fundamental resonant
mode).
