Time Frequency EWOS16-UW Ultra Low Power micro-OCXO for Underwater Systems PRODUCT OVERVIEW EWOS16-UW is a customized micro-OCXO for underwater systems with a record low power consumption at 50 mW at 25°C to optimize the mission time and downsize the battery. Powered with 5V, it delivers an ultra-stable frequency of 16.384 MHz with a record low thermal sensitivity ±50ppb (typ). EWOS16-UW can be disciplined thanks to its tuning pin and is highly resistant to shocks and vibrations. KEY FEATURES 5V supply and 16,384 MHz clipped sine output 50 mW @ 25°C (typ.) ±2 ppb/day after 30 days (typ.)
