780.881 MHz

The output of this device is generated and filtered by narrowband quartz SAW elements at 780.881 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 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:

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.

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.
