SM76D Series 5.0 V  
CMOS Clock Oscillators  
March 2008  
• Pletronics’ SM76D Series is a quartz crystal  
controlled precision square wave generator with a  
CMOS output. Made from SM77D device.  
• The SM76D series will directly interface TTL  
devices also.  
• S-Pkg is Solder pad compatible with the Epson  
SG615 and SG8002J and many other 9x14mm  
plastic J lead packages.  
• 70 to 107 MHz  
• 9.04mm x 8.23mm package  
• Enable/Disable Function  
• Disable function includes low standby power  
mode  
• 3rd Overtone Crystals used  
• Improved circuit to minimize oscillator issues  
such as multi-mode output signal.  
• Low Jitter  
• FR4 base with an SM77D series oscillator.  
• Capable of driving up to 30pF capacitive loads  
• Tape and Reel or cut tape packaging available.  
• Has internal bypass capacitor on the Vcc lead  
• Package changed in 2008  
Pletronics Inc. certifies this device is in accordance with the  
RoHS 6/6 (2002/95/EC) and WEEE (2002/96/EC) directives.  
Pletronics Inc. guarantees the device does not contain the following:  
Cadmium, Hexavalent Chromium, Lead, Mercury, PBB’s, PBDE’s  
Weight of the Device: 0.4 grams  
Moisture Sensitivity Level: 1 As defined in J-STD-020C  
Second Level Interconnect code: e4  
Absolute Maximum Ratings:
