This is now the standard Duty Cycle and is no longer needed inthe part number. We will still support part numbers with the ‘S’. For example: SM7745DW and SM7745DSW 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. www.pletronics.com 425-776-1880 2 SM77D Series 2.5 V CMOS Clock Oscillators Feb 2008 Electrical Specification for 2.50V + _10% over the specified temperature range Item Min Max Unit Frequency Range 70 135 MHz Frequency Accuracy “45" -50 +50 ppm “44" -25 +25 “20" -20 +20 Output Waveform Condition For all supply voltages, load changes, aging for 1 year, shock, vibration and temperatures CMOS Output High Level 90 - % of VCC (See load circuit) Output Low Level - 10 % of VCC (See load circuit) Output Symmetry 45 55 % at 50% point of VCC (See load circuit) - 0.6 pS RMS 12 KHz to 20 MHz from the output frequency - 2.5 pS RMS 10 Hz to 1 MHz from the output frequency 50 - Kohm V disable - 30 % of VCC applied to pad 1 V enable 70 - % of VCC applied to pad 1 -10 +10 uA Pad 1 low, device disabled -10 +10 uA Standby Current ICC - 3 uA Enable time - 100 nS Time for output to reach a logic state Disable time - 100 nS Time for output to reach a high Z state Start up time - 10 mS Time for output to reach specified frequency Jitter Enable/Disable Internal Pull-up Output leakage VOUT = VCC VOUT = 0V Operating Temperature Range Storage Temperature Range -10 +70 o -40 +85 o -55 +125 o Typical phase-noise characteristics at 106.25MHz C C to VCC Standard Temperature Range Extended Temperature Range “E” Option C 0 -20 -40 dBc/Hz -60 -80 -100 -120 -140 -160 -180 10 1,000 100,000 10,000,000 Frequency (Hz) www.pletronics.com 425-776-1880 3 SM77D Series 2.5 V CMOS Clock Oscillators Feb 2008 Electrical Specification for 2.50V + _10% over the specified temperature range Item Min Typ Max Unit VOUT High (VOH) 2.5 2.7 - V VCC = 2.97V, IOH = +8 mA VOUT Low (VOL) - 0.3 0.4 V VCC = 2.97V, IOL = -8 mA Output TRISE and TFALL - 1.0 3.0 nS >110 MHz - 1.0 3.0 nS >80 MHz and <110 MHz - 2.0 4.0 nS <80 MHz - 2.5 4.0 nS >110 MHz - 2.5 4.0 nS >80 MHz and <110 MHz - 3.5 6.0 nS <80 MHz - 25 60 mA >110 MHz - 20 50 mA >80 MHz and <110 MHz - 15 40 mA <80 MHz - 38 70 mA >110 MHz - 31 60 mA >80 MHz and <110 MHz - 20 45 mA <80 MHz VCC Supply Current (ICC) Condition CLOAD = 15 pF 10% to 90% of VCC See Load Circuit CLOAD = 30 pF 10% to 90% of VCC See Load Circuit CLOAD = 15 pF CLOAD = 30 pF Specifications with Pad 1 E/D open circuit www.pletronics.com 425-776-1880 4 SM77D Series 2.5 V CMOS Clock Oscillators Feb 2008 Load Circuit and Test Waveform Symmetry Vhigh 90% * Vcc 50% * Vcc 10% * Vcc Vlow Ground Trise Tfall Reliability: Environmental Compliance Parameter Condition Mechanical Shock MIL-STD-883 Method 2002, Condition B Vibration MIL-STD-883 Method 2007, Condition A Solderability MIL-STD-883 Method 2003 Thermal Shock MIL-STD-883 Method 1011, Condition A ESD Rating Model Minimum Voltage Conditions Human Body Model 1500 MIL-STD-883 Method 3115 Charged Device Model 1000 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 www.pletronics.com Label is 1" x 2.6" (25.4mm x 66.7mm) Font is Arial 425-776-1880 5 SM77D Series 2.5 V CMOS Clock Oscillators Feb 2008 Mechanical: Inches A 0.276 + _0.006 7.00 + _0.15 B 0.197 + _0.006 5.00 + _0.15 C 0.068 + _0.018 1.73 + _0.44 D1 0.038 0.96 E1 0.200 5.08 1 0.004 0.10 G1 0.050 1.27 H1 0.055 1.40 I1 0.024 0.60 J1 0.004 0.10R K1 0.008 0.020R F Not to Scale Contacts : Gold 11.8 μinches Pad 1 Typical dimensions 0.3 μm minimum over Nickel 50 to 350 μinches mm 1.27 to 8.89 μm Function Note 1 Output Enable/Disable When this pad is not connected the oscillator shall operate. 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 SM77D Series 2.5 V CMOS Clock Oscillators Feb 2008 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.
