Selection reference · illustrative scenario
Clock roles in the application
Robot controllers, joint drives and navigation processors have distinct timing requirements. Identify controller, industrial-link and timekeeping parts separately in the BOM.
Engineering selection review
Review host inputs, low-voltage domains, communication references and operating environment. Multi-axis synchronization depends on the clock, network and controls, not oscillator jitter alone.
Procurement and documentation
Include controller and drive chips and interfaces and supply voltages, plus the existing full code, sample and production quantities and delivery target. Discuss nominated international brands and domestic candidates separately, confirming parameters and documents by part.
Illustrative validation scenario
Before changing a drive clock, test power-up, motion-load changes, communications and temperature with consistent firmware and board revision.
