QPDS-0001, Rev L, June 2013 (ECO #10851)
CLASS B+ PRODUCTS
HIGH RELIABILITY HYBRID CRYSTAL CLOCK OSCILLATORS
2.5 to 5.0Vdc - 15kHz to 350MHz
Screening - Option S (Modified MIL-PRF-38534, Class K)
Table I
(Example: QT178LD10S-50.000MHz)
NOTES:
1. PIND testing shall be performed using five (5) independent passes and all failures found at the end of each pass are rejected. The
survivors of the last pass are acceptable.
2. Normally frequency aging is up 30 days. However, aging may be ceased if value at 15 days is half than the limit of 30-day aging
value, or continued up to 90 days if value exeeds 30 day aging limit.
