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: SM7745HW and SM7745HSW
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’ll still support part numbers with this load designation.

Output
When this pin is not connected the oscillator shall operate.
Enable/Disable
When this pin is logic low the output will be inhibited (high impedance state.)
Recommend connecting this pin to VCC if the oscillator is to be always on.

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.
