Selection reference · illustrative scenario
Clock roles in the application
Separate sampling references, controller clocks and digital interfaces, then define frequency and synchronization requirements from the audio chipset.
Engineering selection review
Compare phase noise, integrated jitter and supply coupling under matching conditions. A clock improvement does not directly establish a subjective sound or system-distortion improvement.
Procurement and documentation
Include audio chip and sampling architecture and frequency and synchronization, 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
Compare candidates at fixed sample modes, supplies and connections, then test interface lock, mode changes and enable behavior.
