Test Conditions
Standard atmospheric conditions: Ambient temperature 255, Relative humidity 40%~70%.
Measurement within limits: Ambient temperature 253, Relative humidity 40%~70%.
Measurement equipment: MD 37WX-05M or equivalent.
Crystal Cutting Type
AT CUT (thickness shear mode)
Output Enable/Disable Functionality
Control input (output enable/disable):
- Logic 1 or open on pad 1: Oscillator output enabled.
- Logic 0 on pad 1: Disable output to high impedance.
When the device is in standby, the oscillator stops. When standby is released, the oscillator starts and stable oscillator output occurs after a short delay.
