Description
Low Phase Noise Vcxo 12mhz To 25mhz
Manufacturer
PhaseLink Corp.
Datasheet
FEATURES
DESCRIPTION
The PLL502-05 is a low cost, high performance and
low phase noise VCXO, providing less than -135dBc
at 10 kHz offset in the 12MHz to 25MHz operating
range. The very low jitter (2.2ps 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).
