... 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 ...

... Low Jitter and Phase Noise - low clock jitter (or low phase noise in the frequency domain) is critical to achieving low bit error rates in optical data communications systems. The OP4005B provides very low free-running jitter and phase noise at the OC-12 clock rate, as shown in Figures 1 and 2. This makes the OP4005B an excellent reference for the generation or regeneration of low-jitter clocks and data streams from the OC-12 rate up through OC- 768. The OP4005B achieves this performance over its full -40 to +85 ° ...

... OP4005B. Most operational amplifiers used in active loop filters will be stable when driving the tuning port directly. Special care are should be taken to avoid ground loops in the path from the output of the phase detector though the loop filter to the tuning input of the OP4005B. For most applications, the bandwidth of the loop filter in a OP4005B PLL will be less than 50 Hz, as discussed in the example OP4005B PLL application section below ...

... MHz reference clock with the very low jitter and phase noise of the OP4005B. A block diagram of the PLL is shown in Figure 6. A sample of the OP4005B output is divided by 32 and is compared to a 19.44 MHz reference clock in the phase detector. The loop filter at the output of the phase detector is set to a very low bandwidth (less than 50 Hz typical) ...
