Selection reference · illustrative scenario
Clock roles in the application
Sampling, data interfaces, actuator control and experiment records use different timing requirements. Review measurement references separately from log timekeeping.
Engineering selection review
Review frequency and noise conditions against the acquisition chip while identifying control and RTC functions. Analytical performance depends on the entire measurement chain.
Procurement and documentation
Include acquisition and interface chips and noise and jitter definitions, 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
Keep experiment mode, board and test conditions consistent while reviewing reference start-up, acquisition timing and logs before approving a replacement.
