Today’s Questions and Answers:
Q1. What is oscillator aging and what are the aging specifications for this product series?
A1. Aging is the systematic change in frequency with time due to internal changes in the crystal and/or oscillator. Aging is often expressed as a maximum value in parts per million per year [ppm/year]. The rate of aging is logarithmic in nature. The following factors effect oscillator aging: adsorption and desorption of contamination on the surfaces of the quartz, stress relief of the mounting and bonding structures, material outgassing, and seal integrity. The oscillator aging specification is listed on the datasheet.
Q2. My design work requires the analysis of clock signals. Are IBIS models available for ILSI/MMD/Ecliptek quartz crystal oscillators?
A2. Input/Output Buffer Information Specification (IBIS) modeling information is available. ILSI/MMD/Ecliptek provides this information to assist engineering in the design of their clock tree. Please provide your sales representative with the ILSI/MMD/Ecliptek part number.
Q3. Can ILSI/MMD/Ecliptek provide reliability information for its product series?
A3. Failure in Time (FIT) and Mean Time to Failure (MTTF) reliability data is available for all ILSI/MMD/Ecliptek product series. Please provide your sales representative with the ILSI/MMD/Ecliptek part number.
