Selection reference · illustrative scenario
Clock roles in the application
Video processing, display and transport interfaces may use different reference clocks. Identify sources and synchronization methods by receiver.
Engineering selection review
Review interface frequency, signaling and jitter requirements together with PLLs and distribution. Device parameters do not replace equipment interface validation.
Procurement and documentation
Include video-processing / receiver chip and resolution and interface mode, 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
Retest candidates at target resolution, refresh modes and connections, recording lock, switching, extended operation and temperature behavior.
Inquiry & validation checklist
- Video-processing / receiver chip
- Resolution and interface mode
