DESCRIPTION
The PL502-04 is a low cost, high performance, low
phase noise VCXO, providing less than -128dBc at
10kHz offset in the 96MHz to 200MHz operating
range. 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 12MHz to 25MHz (fundamental resonant
mode).

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permane nt damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional oper ations of the device at these or any other co n-
ditions above the operational limits noted in this specification is not implied. Note: Operating Temperature is guaranteed by design for all parts (CO M-
MERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.
