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 in
the part number. We will still support part numbers with the ‘S’. For example SM7645DV and SM7645DSV
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.

Mechanical (obsolete version):
The cover is no longer being supplied over this part. This part is made with a hermetically sealed SM77D
series oscillator. This part is now exposed.
The cover has been deleted as it was causing problems with the newer high temperature RoHS lead free
processes. The cover purpose was only cosmetic.
All parts ordered in 2008 will be made in the new fashion.
There is no change in electrical properties.
Pletronics does recommend that all designs should transition to the SM77D ceramic part. This is the base
part of the SM76D.

The package is not hermetically sealed.
The sides are intentionally left open to permit cleaning material to freely flow in the package, thus
minimizing the accumulation of contaminants during cleaning processes.
The internal part of the package must be thoroughly dry before operating.
