Quartz SAW Stabilized Differential Output Technology
Very Low Jitter Fundamental-Mode Operation at 622.08 MHz
Voltage Tunable for Phase Locked Loop Applications
Timing Reference for Optical Data Communications Systems
The OP4005B1 is a voltage-controlled SAW clock (VCSC) designed for phase-locked loop (PLL) applications
in optical data communications systems. The differential outputs of the OP4005B1 are generated by high-Q,
fundamental mode quartz surface acoustic wave (SAW) technology. This technique provides very low output
jitter and phase noise, plus excellent immunity to power supply noise. The OP4005B1 differential outputs fea-
ture ±1% symmetry, and can be DC-configured to drive a wide range of high-speed logic families. The
OP4005B1 is packaged in a hermetic metal-ceramic LCC.

and aging.
3. The internal design, manufacturing processes, and specifications of this device are subject to change without notice.
4. Specified only for a balanced load with a VSWR < 1.2 ( 50 ohms each side), and a V
CC
= 3.0 Vdc.
5. Symmetry is defined as the width in (% of total period) measure at 50% of the peak-to-peak voltage of either output.
6. Jitter and other noise outputs due to power supply noise or mechanical vibration are not included in this specification except where noted.
7. Applies to period jitter of either differential output. Measured with a Tektronix CSA803 signal analyzer with at least 1000 samples.
8. One or more of the following United States patents apply: 4, 616,197; 4,670,681; 4,760,352.
