Pad 1
Function Output Enable/Disable No connect Ground (GND) Output Output* Supply Voltage (VCC)
Note When this pad is not connected the oscillator shall operate. When this pad is <0.30 volts, the output will be inhibited (high impedance state.) Recommend connecting this pad to VCC if the oscillator is to be always on. There is no internal connection to this pad
2 3 4 5 6
The outputs must be terminated, 100 ohms between the outputs is the ideal termination. Recommend connecting appropriate power supply bypass capacitors as close as possible.
Layout and application information
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable on both input pads For Optimum Jitter Performance, Pletronics recommends: * a ground plane under the device * no large transient signals (both current and voltage) should be routed under the device * do not layout near a large magnetic field such as a high frequency switching power supply * do not place near piezoelectric buzzers or mechanical fans.
