Pierce Analyzer System (PAS)
Advanced Board Characterization Service
Abracon PAS System enables us to offer Automotive, Medical, and Industrial application customers a
comprehensive, automated assessment of the Pierce Oscillator loop, in concert with the customers selected Quartz
Crystal. The PAS System Circuit Analysis report is ideally suited for PPAP documentation, design history
reporting, and overall assurance of a reliable optimized circuit.
Features:
• Circuit characterization; providing best possible match between Quartz Crystal, oscillator loop and
associated components
• Eliminates probability of oscillator start-up issues related to inadequate design or marginal component
performance
• Eliminates production launch issues related to crystal oscillator based timing circuit
• Solves design margin uncertainty
Deliverables:
A detail Report encompassing:
•
Stand alone Quartz Crystal characteristics including:
- Motional parameters (Cm, Lm, ESR & C0)
- Narrow Band Frequency Response Plot
- Wide Band Frequency Response Plot
- Admittance versus Susceptance plot
- Frequency dependence versus load capacitance plot
•
Oscillator loop characteristics including:
- Initial frequency accuracy and drive level as seen by the crystal with measured ESR
- Worst case projected drive level with maximum specified ESR
- Safety Factor of the oscillator loop under both typical and maximum ESR
- Recommendation on proper component selection (C1, C2 & Rs when applicable) for
best compromise with respect to Safety Factor and Frequency accuracy
- Recommendation on the Abracon Crystal part # with proper plating load and other key
attributes to enable the most robust design, specific to the µcontroller/processor implemented
