Abstract: Many industrial/scientific/medical (ISM) band radio frequency (RF) products use crystal oscillators to generate a reference for the phase-locked loop (PLL)-based local oscillator (LO). This ...
Today, most GSM handsets use voltage-controlled, temperature-compensated crystal oscillator (VC-TCXO) modules as the system reference oscillator. To establish and maintain a robust wireless connection ...
Using this Pierce-oscillator circuit, users can test and verify the basic operation of a crystal in parallel-resonance mode. It allows the user to calculate and set the critical external capacitor ...
