Control input (output
enable/disable)
Logic 1 or open on pad 1:
Oscillator output
Logic 0 on pad 1 : Disable
output to high impedance
5. WAVEFORM CONDITIONS
Waveform measurement
system should
have a min. bandwidth of 5
times the
frequency being tested.
6. OUTPUT ENABLE / DISABLE DELAY
The following figure shows the oscillator timing during normal operation . 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
