Note
If this function is not specified, recommend connecting this pad to ground.
The output is DC coupled. Most common used with external coupling capacitor.
0.001 to 0.01uF recommended
Recommend connecting appropriate power supply bypass capacitors as close
as possible.
Layout and application information
The area under the device should have no exposed contacts except the 4 pad areas. Placing solder mask
under the device and covering all feed throughs is highly recommended.
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.
