OP4012B Performance Parameters
The OP4012B has been developed to achieve high performance in five parameters critical to optical data communications applications:
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 OP4012B provides very low free-running jitter and phase noise as shown in Figures 1 and 2. This makes the OP4012B an
excellent reference for the generation or regeneration of low-jitter clocks and data streams. The OP4012B achieves this performance over its full -40 to +85
°C operating temperature range using RFM's patented SAW oscillator architecture.
Single-Sideband Phase Noise

High Power Supply Noise Immunity - the OP4012B uses both differential active devices and differential SAW technology to minimize the effects of power
supply noise on jitter and phase noise, as shown in Figures 2 and 3. Optical data communications circuits must switch relatively high levels of current,
making power supply noise immunity an important clock requirement.
Controlled Tuning Characteristics - the OP4012B voltage tuning constant, K V , is bounded between 100 and 260 ppm/V under locked conditions for
reference signals with ±100 ppm or better stability over the OP4012B's full operating temperature and supply voltage range. This allows a PLL based on
the OP4012B to be designed with a well-controlled loop bandwidth and damping factor, avoiding problems such a jitter peaking, etc. The voltage tuning
characteristic of the OP4012B is monotonic from 0 to 3.3 V, supporting reliable acquisition of phase lock. Figure 4 shows typical OP4012B tuning
characteristics.
