The typical supply voltage range for industrial PLL ICs is 3.3–5.0 V DC. However, always check the datasheet of the specific model, as some devices may have different requirements.
A PLL uses a phase detector to compare the phase of the VCO output with the reference input. The resulting error voltage is filtered and applied to the VCO, adjusting its frequency until the phase difference is minimized, achieving lock.
Lock time is the time required to achieve phase lock after a frequency change. For typical industrial PLLs, this ranges from 1 to 10 ms, but it depends on the loop filter design and the frequency step.
The ESD rating for PLLs is often specified per the human body model (HBM) and may reference standards such as IEC 61340-3-1. The typical range is 2–4 kV, but verify the specific model's compliance.
