Selection reference · illustrative scenario
Clock roles in the application
Voice, camera and connected glasses use different feature combinations. Define processing, audio, image and standby clocks separately.
Engineering selection review
Review height, supply, AV interfaces, wake recovery and any required clock-domain relationship. Translation and voice performance cannot be inferred from source noise alone.
Procurement and documentation
Include controller and av chips and height 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
Switch between recording, capture, connected and standby modes, logging enable behavior, temperature and power before selecting the component set.
