Selection reference · illustrative scenario
Clock roles in the application
FPGA boards may need configuration, sampling and serial-link references. Distinguish independent domains from clocks requiring a defined phase or frequency relationship.
Engineering selection review
Review receiver banks, signaling standards, termination and internal PLL configuration together. Interface compliance requires its specified measurement method rather than a generic jitter figure.
Procurement and documentation
Include fpga and receiver banks and configuration, sampling and link frequencies, 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
Test reconfiguration, cold start and link training across operating temperatures. Multiple independent oscillators do not automatically form a common-source clocking scheme.
