Electrical Specifications

The oscillator operates at a nominal frequency of 40.000MHz, with an inclusive frequency tolerance/stability of ±5ppm. It accounts for various factors, including calibration tolerance, temperature fluctuations, supply voltage variation, aging, and the effects of shock and vibration. The device specifies a maximum aging rate of ±5ppm per year at 25°C.

The temperature range for operation is specified from -40°C to +85°C. It requires a 3.3Vdc supply voltage with an input current of 18mA maximum. Additionally, the datasheet provides detailed levels for output voltage logic high (90% of Vdd minimum) and low (10% of Vdd maximum), rise/fall time (3nSec maximum), duty cycle (50±10%), and load drive capability of 15pF maximum. It utilizes CMOS output logic with tri-state output control enabling or disabling the output depending on the input voltage applied.

The device includes a low standby current of 10μA maximum for disabled outputs and specifies an RMS phase jitter of 1pSec maximum within a 12kHZ to 20MHZ offset frequency. Startup time is noted at 10mSec maximum, and the oscillator can withstand storage temperatures between -55°C to +125°C.

Environmental & Mechanical Specifications

Robustness against various environmental and mechanical stresses is ensured, with the oscillator meeting military standards and tests for ESD susceptibility (MIL-STD-883, Method 3015), leak tests, flammability (UL94-VO), mechanical shock, moisture resistance, resistance to soldering heat, resistance to solvents, solderability, temperature cycling, and vibration. These standards ensure reliability in diverse operational environments.
