DESCRIPTION

MULTIPLIER

96 - 200MHz

CMOS

The ABX0204 is a low cost, high performance and

low phase noise XO, providing less than -125 dBc at

10kHz offset in the 96MHz to 200MHz operating

range. The very low jitter (4ps RMS period jitter)

makes this chip ideal for 155.52MHz SONET and

SDH applications, and for 125MHz and 106.25MHz

applications. 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 con-

ditions above the operational limits noted in this specification is not implied.

* Note: Operating Temperature is guaranteed by design for all parts (COMMERCIAL and INDUSTRIAL), but tested for COMMERCIAL grade only.
