Selection reference · illustrative scenario
Clock roles in the application
Edge gateways and vision terminals often combine compute, imaging, wireless and low-power timing. One part need not cover every clock function.
Engineering selection review
Separate host and high-speed-interface requirements, then review supply domains, board temperature, RTC backup and wake behavior in the actual installation.
Procurement and documentation
Include soc, imaging and wireless modules and board temperature and supply domains, 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
Review temperature and clock behavior under changing processing load, plus reboot, reconnection and timestamps, retaining hardware and software revisions.
