Marking
Details not provided in the input text.
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
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.
Suggested Reflow Profile
Total time: 200 sec. Max / Solder melting point: 220
