Test Circuit: Control input (output enable/disable) Logic 1 or open on pad 1: Oscillator output. Logic 0 on pad 1: Disable output to high impedance.
Waveform Conditions: Waveform measurement system should have a minimum bandwidth of 5 times the frequency being tested.
Timing during normal operation. 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.
