• Voltage Tunable for Phase Locked Loop Applications
• Timing Reference for Optical Data Communications Systems
• Complies with Directive 2002/95/EC (RoHS)
The OP4005B is a voltage-controlled SAW clock (VCSC) designed for phase-locked loop (PLL) applications
in optical data communications systems. The differential outputs of the OP4005B 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 OP4005B differential outputs
feature ±1% symmetry, and can be DC-configured to drive a wide range of high-speed logic families. The
OP4005B is packaged in a hermetic metal-ceramic LCC.

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:
1. Unless otherwise noted, all specifications include the combined effects of load VSWR, V_CC and T_C.
2. Net tuning range after tuning out the effects of initial manufacturing tolerances, VSWR pushing/pulling, V_CC, T_C 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.
9. One or more of the following United States patents apply: 4, 616,197; 4,670,681; 4,760,352.
