Legacy Part Numbers:
‘S’ Denoted Symmetry of 45%/55% at 50% of VCC. This is now the standard Duty Cycle and is no longer needed
inthe part number. We will still support part numbers with the ‘S’. For example: SM7745DW and SM7745DSW
describe the same specifications and can be used interchangeably by the customer.
-30 Denoted Output Load other than the standard 15 pF. Data sheets now reflect the specifications at all available
loads so this load designation is no longer needed. We still support part numbers with this load designation.

Layout and application information
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.
