SiTime provides a recommended PCB layout guideline in their application note AN-002, which includes layout considerations for the oscillator, decoupling capacitors, and signal routing.
SiTime recommends applying a power supply ramp-up time of at least 1 ms to ensure proper startup. The oscillator's internal circuitry requires a certain amount of time to stabilize before outputting a stable clock signal.
While the datasheet specifies a typical operating temperature range of -40°C to 85°C, the oscillator can operate up to 125°C with reduced performance and accuracy. However, it's essential to consult with SiTime for specific guidance on high-temperature operation.
SiTime's oscillators are not designed for use in radiation-intensive environments. If your application requires radiation-hardened components, you should consider alternative oscillator solutions specifically designed for such environments.
SiTime provides a troubleshooting guide in their application note AN-003, which covers common issues such as output signal amplitude, frequency, and jitter. The guide also provides guidance on using oscilloscopes and other measurement tools to diagnose problems.
