MARKING
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
Note that 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
