OP4005B - 2/4/10

• 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

• 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.

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.
