FEATURES
Low phase noise XO output for the 24MHz to
50MHz range (-135 dBc at 10kHz offset).
12 to 25MHz crystal input.
Integrated crystal load capacitor: no external
load capacitor required.
Low jitter (RMS): 3ps period jitter (1 sigma).
Selectable High Drive (30mA) or Standard Drive
(10mA) output.
3.3V operation.
Available in 8-Pin TSSOP or SOIC.
DESCRIPTION
The PLL602-01 is a low cost, high performance and
low phase noise XO, providing less than -135dBc at
10kHz offset in the 24MHz to 50MHz operating
range. The very low jitter (3ps RMS period jitter)
makes this chip ideal for applications requiring clean
reference 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 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.
