Timing Clock  
The output of this device is generated and filtered by narrowband quartz SAW elements at 718.864 MHz. The  
configuration of this clock is intended to provide a pure signal for optical timing applications in noisy signal  
environments. The Q/Qbar differential output swing of ±1 volt about 0 vdc has symmetry better than ±1% into  
loads from 40 ohms to 70 ohms; determined by customer application. The long term frequency accuracy is  
set by an external reference source allowing this device to complete a Phase Lock Loop design without the  
usual noise and jitter problems associated with PLL’s.

The design, manufacturing process, and specifications of this device are subject to change without notice.  
Only under the nominal conditions of 50 W load impedance with VSWR £ 1.2 and nominal power supply voltage.  
Symmetry is defined as the pulse width (in percent of total period) measured at the 50% points of Q or Q. (See: Timing Definitions.)
