PE91 PE97 Function
Pad Pad
Note
2
1 Output
When this pad is not connected the oscillator shall operate. This is not a
Enable/Disable recommended condition!!!!!!
When this pad is <0.80 volts, the output will be inhibited (High impedance state)
Recommend connecting this pad to V_CC if the oscillator is to be always on.
1
2 No function
Recommend connecting this pad to ground. The is internal connection.
3
Ground (GND)
4
Output
5
Output*
Both outputs must be terminated and biased for proper operation. The ideal
termination is 50 ohms connected to 2.0V below the Supply Voltage.
The outputs become a High Z when disabled and the voltage level is determined
by the termination circuitry.
6
Supply Voltage Recommend connecting appropriate power supply bypass capacitors as close as
(V_CC)
possible.
