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.
Output Enable / Disable Delay
The oscillator stops when the device is in standby. When standby is released, the oscillator starts and a stable output occurs after a short delay.
Suggested Reflow Profile
Total time: 200 sec. Max / Solder melting point: 220
