Operating Principle

The SI5338C-B01232-GMR makes use of a quartz crystal as a timing reference. Quartz crystals are formed through the combination of silicon, oxygen, and several other elements, with silicon providing the crystal’s inherently stable frequency. Through a process of deposition and etching, an electrode is placed at each end of the crystal, forming an oscillator circuit.

The oscillator includes a quartz crystal, along with a drive source, feedback resistor, and a series of capacitors. The oscillator is tuned by adjusting the capacitive loading of the quartz element with the capacitors and other components. A specific frequency is achieved with a combination of the quartz crystal’s mechanical properties and the way it is tuned with the capacitors. This oscillator circuit produces a signal with a frequency equal to the mechanical oscillation frequency of the quartz crystal.

When the oscillator is fed into a counter chain, the oscillator’s frequency can be divided down to create one or more clock signals that meet the application’s timing requirements. The counter chain can also be used to enable features such as programmable frequency selection, frequency modulation, and multipliers. The SI5338C-B01232-GMR also boasts a wide pull range, allowing users to make slight adjustments to their timing reference.
