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.

When this pad is logic low the output will be inhibited (high impedance state.) Recommend connecting this pad to VCC if the oscillator is to be always on. 2 Ground (GND) 3 Output 4 Supply Voltage (VCC) Recommend connecting appropriate power supply bypass capacitors as close as possible. 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. www.pletronics.com 425-776-1880 6 SM76D Series 3.3 V CMOS Clock Oscillators March 2008 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.
