PLL/DLL architecture, jitter budgeting, lock behavior, and digital-side debug for resilient clock integration.
Start with topic hubs to learn contract and ownership.
Use mechanism and reports pages to map symptoms to root causes.
Use debug and worked-example pages for war-room practice.
Close with checklist and PPA pages before signing any change.

Clock quality evidence must include jitter and sequencing, not lock status alone.
