The output of this device is generated and filtered by narrow-band quartz SAW elements at 669.327 MHz.
The configuration of this clock provides a pure signal for optical timing applications in noisy signal
environments. The Q/Q differential output swing of ±1 volt about 0 Vdc has symmetry better than ±1% into
loads from 40 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.

Unless otherwise noted, all specifications include any combination of load VSWR, Vcc, and temperature, with Q and Q terminated into 50 ohm loads to
ground (see typical test circuit).
Useful tuning range is in excess of what is required over temp, aging, pushing, pulling & accuracy.
The design, manufacturing process, and specifications of this device are subject to change without notice.
Only under the nominal conditions of 50 ? 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).
Jitter and other spurious outputs induced by externally generated electrical noise on V CC or mechanical vibration are not included in this specification, except
where noted. 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.
Linearity is a function of the percentage variation from a permitted linear deviation versus the amount of frequency tune range (see linearity definition).
One or more of the following United States patents apply: 4,616,197; 4,670,681; 4,760,352.
Over the range of 669.327 MHz ±25 ppm and the conditions of Note 1.
