High-Reliability Standards

Source Control Drawing Alternatives at Your Fingertips

Our high-reliability standards, which govern most of our radiation-tolerant space oscillator platforms, eliminate the need to create source control drawings. These documents allow OEMs to specify the enclosure, output waveform, nominal frequency, temperature stability, supply voltage, element evaluation, screening level and radiation tolerance requirements through a 15- or 16-digit part number string. Since 2000, we’ve used high-reliability standard documentation in place of customer-generated SCDs, a practice that has quickly become the industry standard for many of today's leading satellite OEMs. Mutual benefits are realized by both the customer and the supplier:

Customer Advantages

Customer Advantages

  • No OEM SCD or custom part numbers required
  • Ordering codes define EEE pedigree and QA level

Design Pedigree

Design Pedigree

We can tailor the component pedigree of our high-reliability oscillators to ensure you meet your program cost and lead time requirements. Various combinations and options are included in most specifications. Please refer to the individual product specifications for ordering options. These options include:

  • Swept versus non-swept quartz
  • Enhanced element evaluation
  • 300-krad, 100-krad or untested wafer lots
  • Class S, Class B or ruggedized COTS components
Screening and Qualification

Screening and Qualification

Our oscillators are available with predefined screening options based upon MIL-PRF-38534 and MIL-PRF-55310 standards and an Engineering Model (EM) option. The screening options include common test methods such as non-destruct bond pull, burn-in, thermal shock, fine and gross leak and PIND testing. Screening options vary slightly by specification; please review the appropriate catalog specifications. These options include:

  • MIL-PRF-38534 Class K screening
  • Modified MIL-PRF-55310 Class B screening and Group A QCI
  • Modified MIL-PRF-55310 (Rev E) Class S screening and Group A QCI
  • Modified MIL-PRF-38534 Class K screening, Group A QCI and 30-day aging
  • MIL-PRF-55310 Class B screening and Groups A and B QCI
  • MIL-PRF-55310 (Rev E) Class S screening and Groups A and B QCI
  • Modified MIL-PRF-55310 Class B screening and Post burn-in electrical
  • MIL-PRF-55310 (Rev F) Class S screening and Groups A and B QCI
  • Engineering Model (EM)
