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: SM7745DY and SM7745DS 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 5.0 V CMOS Clock Oscillators Feb 2008 Electrical Specification for 5.00V +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 0.5 45 Enable/Disable Internal Pull-up V disable V enable Output leakage VOUT = VCC VOUT = 0V Enable time Disable time Start up time Operating Temperature Range 50 2.0 -10 -10 -10 -40 Storage Temperature Range -55 Min 70 -50 -25 -20 Max 107 +50 +25 +20 CMOS 0.4 55 1 4 0.5 +10 +10 100 100 10 +70 +85 +125 V V % pS RMS pS RMS Kohm V V 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 Below VCC (See load circuit) (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 Applied to pad 1 Pad 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 SM77D Series 5.0 V CMOS Clock Oscillators Feb 2008 Electrical Specification for 5.00V +10% over the specified temperature range _ Item VOUT High (VOH) VOUT Low (VOL) Output TRISE and TFALL Min 0.5 VCC Supply Current (ICC) Typ 0.3 0.3 2.0 3.0 50 45 60 50 Max 0.4 4.0 6.0 90 80 100 100 Unit V V nS nS mA mA mA mA Condition Below VCC, IOH = +16 mA IOL = -16 mA CLOAD = 15 pF, CLOAD =30 pF, >100 MHz 100 MHz
