Description
Low Phase Noise Vcxo 12mhz To 27mhz - Phaselink Corporation
Manufacturer
PhaseLink Corp.
Datasheet
1.P502-25SC.pdf (4 pages)
FEATURES
x Low phase noise VCXO output for the 12MHz to
x CMOS output.
x 12 to 27MHz crystal input.
x Integrated variable capacitors.
x Wide pull range (+/- 250 ppm).
x Low jitter (RMS): 2.2ps period.
x 2.5V or 3.3V operation voltage.
x Available in 8-Pin SOIC.
DESCRIPTION
The PLL502-25 is a low cost, high performance and
low phase noise VCXO, providing less than -135dBc
at 10kHz offset in the 12MHz to 27MHz operating
range. The very low jitter (2.2 ps RMS period jitter)
makes this chip ideal for applications requiring volt-
age controlled frequency sources. Input crystal can
range from 12 to 27MHz (fundamental resonant
mode).
