Quartz SAW Stabilized Differential Output Technology
Very Low Jitter Fundamental-Mode Operation at 666.51 MHz
Voltage Tunable for Phase Locked Loop Applications
Optical Timing Reference for Forward Error Correction Applications
The OP4006B1 is a voltage-controlled SAW clock (VCSC) designed for phase-locked loop (PLL) applications
in optical data communications systems. The differential outputs of the OP4006B1 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 OP4006B1 differential outputs fea-
ture ±1% symmetry, and can be DC-configured to drive a wide range of high-speed logic families. The
OP4006B1 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. See Figure 4.
