Clock  
This digital clock is designed for use with high-speed CPUs and digitizers. Fundamental-mode oscillation is  
made possible by surface-acoustic-wave (SAW) technology. The design results in low jitter, compact size,  
and low power consumption. Differential outputs provide a sine wave that is capable of driving 50 W loads.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.  
NOTES:  
1.  
Unless otherwise noted, all specifications include any combination of load 6.  
VSWR, VCC, and TA. In addition, Q and Q are terminated into 50 W loads to  
ground. (See: Typical Test Circuit.)  
Jitter and other spurious outputs induced by externally generated electrical noise  
on VCC or mechanical vibration are not included. Dedicated external voltage  
regulation and careful PCB layout are recommended for optimum performance.  
Applies to period jitter of Q and Q. Measurements are made with the Tektronix  
CSA803 signal analyzer with at least 1000 samples.  
Period jitter measured with a 200 mVP-P sine wave swept from 1 MHz to one-half  
of fO at the VCC power supply terminal.  
The outputs are enabled when Terminal 8 is at logic HIGH. Propagation delay is  
defined as the time from the 50% point on the rising edge of ENABLE to the 90%  
point on the rising edge of the output amplitude or as the fall time from the 50%  
point to the 10% point. (SEE: Timing Definitions.)

One or more of the following United States patents apply: 4,616,197; 4,670,681;  
4,760,352.  
7.  
The design, manufacturing process, and specifications of this device are subject  
to change without notice.  
8.  
Only under the nominal conditions of 50 W load impedance with VSWR £ 1.2 and  
nominal power supply voltage.  
9.  
Symmetry is defined as the pulse width (in percent of total period) measured at  
the 50% points of Q or Q. (See: Timing Definitions.)
