LMC555CMMX Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the LMC555CMMX is 3 MHz, but it can be pushed to 5 MHz with some external component tuning.
  • To ensure reliable oscillator startup, make sure the power supply voltage is stable, and the timing capacitor (Ct) is properly selected. A good starting point is to use a Ct value between 10 nF and 100 nF.
  • The control voltage (CV) pin is used to adjust the oscillator frequency. By applying a voltage to this pin, you can modulate the oscillator frequency, making it useful for applications like FM modulation.
  • The choice of resistor and capacitor values depends on the desired oscillator frequency and the specific application. A good starting point is to use the values recommended in the datasheet, and then adjust them based on the specific requirements of your design.
  • The maximum output current of the LMC555CMMX is 200 mA, but it's recommended to keep the output current below 100 mA to ensure reliable operation.
