Preliminary OP4007B • • • • Quartz SAW Stabilized and Filtered “Diff Sine” Technology Fundamental-Mode Oscillation at 669.128 MHz Voltage Tunable for Phase Lock Loop Operations Optical Timing Reference for Forward Error Correction Applications 669.128 MHz Optical Timing Clock The output of this device is generated and filtered by narrowband quartz SAW elements at 669.128 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.

In addition, Q and Q are terminated into 50 Ω loads to ground. (See: Typical Test Circuit.) Customer useful tune range in excess of what part requires 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 Ω 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 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.
