CORPORATION

Low Cost Space Crystal Oscillator

1.8V, 2.5V, 3.3V, 5Vdc

225kHz to 162.5MHz

Description

Q-Tech’s low profile extreme high shock hybrid

oscillators consist of an IC operating at various supply

voltages from 1.8V, 2.5V, 3.3V, and 5.0Vdc and a

miniature strip quartz crystal. The series is offered in

various ceramic package configurations from true

Surface-Mount SMT to straight leads and formed leads.

This is the smallest package offered with a 50kRad(Si)

TID for Low Earth Orbit (LEO) with high shock and high

reliability space applications.

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.

3. Aging is ±5ppm after first year and ±2ppm/year thereafter.
