Oscillators FAQ

How does the tri-state pin function on this oscillator?

The tri-state pin controls the output state. When held at a high impedance level, the output is enabled. When pulled low, the output enters a high-impedance disabled state, reducing current consumption.

What is the maximum frequency tolerance for this model?

The maximum frequency tolerance and stability is ±45ppm. This value includes all conditions such as calibration tolerance at 25°C, frequency stability over the operating temperature range, supply voltage changes, output load changes, first-year aging, shock, and vibration.
