CMOS
The ABV0203 is a low cost, high performance and
low phase noise VCXO for the 48 to 100MHz range,
providing less than -130dBc at 10kHz offset at
48MHz. The very low jitter (3.5ps 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).

Exposure of the device under conditions beyond the limits specified by Maximum Ratings for extended periods may cause permanent damage to the
device and affect product reliability. These conditions represent a stress rating only, and functional operations of the device at these or any other
conditions above the operational limits noted in this specification is not implied.

Note: Crystal Loading rating: 9.5pF is the loading the crystal sees from the VCXO chip at VCON = 1.65V. It is assumed that the crystal will be at
nominal frequency at this load. If the crystal requires more load to be at nominal frequency, the additional load must be added externally.
This however may reduce the pull range.
