Quartz SAW Stabilized and Filtered “Diff Sine” Technology
Fundamental-Mode Oscillation at 663.552 MHz
Voltage Tunable for Phase Lock Loop Operations
663.552 MHz
Optical
Timing Clock
Optical Timing Reference for Forward Error Correction Applications
The output of this device is generated and filtered by narrowband quartz SAW elements at 663.552 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.

BLOCK DIAGRAM
1.
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 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).
Jitter and other spurious outputs induced by externally generated electrical noise on VCC or mechanical vibration are not included in this

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 lin-
earity definition).
