Frequency stability vs. Change in temperature, referenced to 25C. Frequency stability per 5% change in supply voltage. At the time of shipment after 48 hours of operation. Inclusive of calibration, operating temperature range, supply voltage change, shock and vibration 20 years aging. Typical phase noise, results will vary depending on center frequency. The phase noise shown are typical for 20 MHz. Measured @ 25C, within 3 minutes, the unit will be within +/-0.1ppm of its reference frequency, measured after 30 minutes of continuous operation at a stable 25C. 2111 Comprehensive Drive Aurora, Illinois 60505 Phone: 630- 851- 4722 Fax: 630- 851- 5040 www.conwin.com 14 Pin DIP Package Environmental Characteristics ENVIRONMENTAL CHARACTERISTICS Temperature Cycle: Per MIL-STD-883, Method 1010, Condition B. -55°C to 125°C, 300 cycles,1 0 minute dwell, 1minute transition.
