719.734 MHz
Optical
The output of this device is generated and filtered by narrowband quartz SAW elements at 719.734 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.

CAUTION: Electrostatic Sensitive Device. Observe precautions for handling.
COCOM CAUTION: Approval by the U.S. Department of Commerce is required prior to export of this device.
Notes:
1. Unless otherwise noted, all specifications include any combination of load VSWR, VCC, and TC. In addition, Q and Q are terminated into 50 Ω loads
to ground. (See: Typical Test Circuit.)
2. Customer useful tune range in excess of what part requires over temp, aging, pushing, pulling & accuracy.
3. The design, manufacturing process, and specifications of this device are subject to change without notice.
4. Only under the nominal conditions of 50 Ω load impedance with VSWR ≤ 1.2 and nominal power supply voltage.
5. Symmetry is defined as the pulse width (in percent of total period) measured at the 50% points of Q or Q. (See: Timing Definitions.)
6. 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.
7. Applies to period jitter of Q and Q. Measurements are made with the Tektronix CSA803 signal analyzer with at least 1000 samples.
8. Linearity is a function of the percentage variation from a permitted linear deviation versus the amount of frequency tune range. See Linearity
Definition.
9. One or more of the following United States patents apply: 4,616,197; 4,670,681; 4,760,352.
