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: SM7745HX and SM7745HSX 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 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. 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 SM77H Series 1.8 V CMOS Clock Oscillators April 2007 Temperature (°C) Reflow Cycle (typical for lead free processing) 260°C Maximum 10 Seconds Maximum 250 215°C±10°C 200 175°C±10°C 150 100 Approximately 50 Seconds 120 to 160 Seconds Allowed rate of temperature change Maximum 4°C per second The part may be reflowed 2 times without degradation.
