ABX0203  
Low Phase Noise CMOS XO (48MHz to 100MHz)  
FEATURES  
PIN CONFIGURATION  
•
Low phase noise XO output for the 48MHz to  
100MHz range (-130 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.

DESCRIPTION

48 - 100MHz  
CMOS  
The ABX0203 is a low cost, high performance and  
low phase noise XO, providing less than -130dBc at  
10kHz offset in the 48MHz to 100MHz 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.
