Standard Specifications

Overall Frequency Stability

SM1145C: ± 50 PPM, SM1144C: ± 25 PPM over Operating Temperature Range

Operating Temperature Range 0 to +70 C is standard, but can be extended to 40 to +85°C for certain frequencies

Supply Voltage (Vcc)

Symmetry (Duty Cycle)

Logic Levels

5.0 volts and 3.3 volts available, .01 µF bypass cap recommended

40/60 to 60/40% is standard, but 45/55% at 50% of Vcc is also available (see Waveform 1)

Logic “1” 90% of Vcc MIN; Logic “0” 10% of Vcc MAX

Output Load

Enable/Disable Option (E/D)

Standard load is 15pF maximum, see Test Circuit 2 (consult factory for heavier loads)

Output enabled when Pin #1 is open or at Logic “1”; Output disabled when Pin #1 is at Logic “0”.
