Dimensions
(Units :mm)
Dimensions are provided in the original document but not extracted here due to lack of explicit table format.
Marking
Marking details are provided in the original document but not extracted here due to lack of explicit table format.
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 min. bandwidth of 5 times the frequency being tested.
Output Enable / Disable Delay
The oscillator timing during normal operation is shown in the original document. 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
