Dimensions
Units: mm
2.5 x 2.0
Test Conditions
Standard atmospheric conditions: Ambient temperature: 255, Relative humidity: 40%~70%.
Measurement limits: Ambient temperature: 253, Relative humidity: 40%~70%.
Measurement equipment: MD 37WX-05M or equivalent.
Test Circuit Description
Control input (output enable/disable): Logic 1 or open on pad 1 enables the oscillator output. Logic 0 on pad 1 disables the 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 device timing during normal operation is shown in the figure. When the device is in standby, the oscillator stops. Upon release from standby, the oscillator starts and provides a stable output after a short delay.
Suggested Reflow Profile
Total time: 200 sec. Max / Solder melting point: 220
