CMOS clock oscillator is MIL approved

The M55310/30-B Series, Type 1 crystal clock oscillators (XO) are available in a frequency range of 450 kHz to 100 MHz. Typical frequency stability is less than ±5 ppm at 23°C and less than 30 ppm over –55° to 125°C. Aging characteristics are typically less than ±1 ppm per year. Standard environmental performance for; hermeticity is per MIL-PRF-55310 (max. leakage rate 5x 10E-8 atm-cc/s (atmosphere-cubic centimetre per second)), vibration-mechanical is per MIL-STD-202 (method 204D, cond. D), terminal strength is per MIL-STD-202 (method 211, cond. A), and the ambient pressure is per MIL-STD-202 (method 105, cond. C).

These XOs operate on a supply voltage of 3.3-Vdc drawing 8 mA on the lower frequency versions and 30 mA on the higher-frequency versions. Delivering a CMOS square wave output with a load of 15 pF ±5%//10 kΩ ±5%. The hermetically sealed SMD package measures 0.560 x 0.360 x 0.188 in. max. (Call company for pricing — 27-MHz version, 8 to 12 weeks ARO.)

NDK has been mass producing quartz crystals of uniform high quality utilizing its own technology. On the basis of this experience NDK manufactures and supplies highly accurate, highly reliable crystal products using advanced technology and thorough quality control techniques.
