Enable/Disable  
When this pad is < ‘V disable’, the output will be inhibited (high impedance state.)

Recommend connecting appropriate power supply bypass capacitors as close as  
possible.  
(V )  
CC  
Layout and application information  
Recommend connecting Pad 1 and Pad 2 together to permit the design to accept Enable/Disable input on  
either pad  
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.
