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 SM7645HW and SM7645HSW 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 will still support part numbers with this load designation. www.pletronics.com 425-776-1880 2 SM76H Series 2.5 V CMOS Clock Oscillators March 2008 Electrical Specification for 2.50V +10% over the specified temperature range _ Item Frequency Range Frequency Accuracy "45" "44" "20" Output Waveform Output High Level Output Low Level Output Symmetry Jitter 90 45 Enable/Disable Internal Pull-up V disable V enable Output leakage VOUT = VCC VOUT = 0V Standby Current ICC Enable time Disable time Start up time Operating Temperature Range 50 70 -10 -10 -10 -40 Storage Temperature Range -55 Min 0.8 -50 -25 -20 Max 69.9 +50 +25 +20 CMOS 10 55 0.6 2.5 30 +10 +10 3 100 100 3 +70 +85 +125 % % % pS RMS pS RMS Kohm % % uA uA uA nS nS mS o o Unit MHZ ppm Condition For all supply voltages, load changes, aging for 1 year, shock, vibration and temperatures of VCC (See load circuit) at 50% point of VCC (See load circuit) 12 KHz to 20 MHZ from the output frequency 10 Hz to 1 MHZ from the output frequency to VCC of VCC applied to pin 1 Pin 1 low, device disabled Time for output to reach a logic state Time for output to reach a high Z state Time for output to reach specified frequency Standard Temperature Range Extended Temperature Range "E" Option C C C o www.pletronics.com 425-776-1880 3 SM76H Series 2.5 V CMOS Clock Oscillators March 2008 Electrical Specification for 2.50V +10% over the specified temperature range _ Item Output TRISE and TFALL Typ VCC Supply Current (ICC) Max 7 9 12 6 8 11 29 7 8 10 41 Unit nS nS nS mA mA mA mA mA mA mA mA Condition All < 35 MHZ > 35 MHZ < 8 MHZ > 8 MHZ and < 16 MHZ > 16 MHZ and < 35 MHZ > 35 MHZ < 8 MHZ > 8 MHZ and < 16 MHZ > 16 MHZ and < 35 MHZ > 35 MHZ CLOAD = 30 pF 10% to 90% of VCC See Load Circuit CLOAD = 15 pF 10% to 90% of VCC See Load Circuit CLOAD = 15 pF CLOAD = 30 pF Specifications with Pad 1 E/D open circuit Typical phase noise plot for 5 oscillators at different output frequencies. 0 -20 -40 -60 dBc/Hz 19.4M 25M 32M 50M 66.7M -80 -100 -120 -140 -160 -180 10 1,000 100,000 10,000,000 Frequency (Hz) www.pletronics.com 425-776-1880 4 SM76H Series 2.5 V CMOS Clock Oscillators March 2008 Load Circuit and Test Waveform Vhigh 90% * Vcc 50% * Vcc 10% * Vcc Vlow Ground Trise Symmetry Tfall Reliability: Environmental Compliance Parameter Mechanical Shock Vibration Solderability Thermal Shock Condition MIL-STD-883 Method 2002, Condition B MIL-STD-883 Method 2007, Condition A MIL-STD-883 Method 2003 MIL-STD-883 Method 1011, Condition A ESD Rating Model Human Body Model Charged Device Model Minimum Voltage 1500 1000 Conditions MIL-STD-883 Method 3115 JESD 22-C101 Package Labeling Label is 1" x 2.6" (25.4mm x 66.7mm) Font is Courier New Bar code is 39-Full ASCII Label is 1" x 2.6" (25.4mm x 66.7mm) Font is Arial www.pletronics.com 425-776-1880 5 SM76H Series 2.5 V CMOS Clock Oscillators March 2008 Mechanical: Inches A 1 4 3 mm 8.23 +0.07 _ 9.04 +0.13 _ 3.43 +0.13 _ 1.57 1.27 1.27 1.50 0.51 1.02 5.08 0.324 +0.003 _ 0.356 +0.005 _ 0.135 +0.005 _ 0.062 0.050 0.050 0.059 0.020 0.040 0.200 B C D 1 2 E1 Label: Laser marked on the ceramic package metal cover FR4 PCB Base: Solder masked All via holes tented on bottom Copper Clad 1/2 oz.

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 3 4 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 SM76H Series 2.5 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 SM77H series oscillator. This part is now exposed. The cover has been deleted, the cover 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 SM77H ceramic part. This is the base part of the SM76H.
