SMD Quartz Crystal P5FA

The oscillator generates cycles of its output signal 25 million times per second. This frequency is commonly used as a clock source in digital circuits and systems to synchronize various components. A 25MHz crystal oscillator is used in a wide range of electronic devices, including microcontrollers, microprocessors, FPGAs (Field-Programmable Gate Arrays), communication devices, wireless modules, digital signal processors (DSPs)
