Working Principle

The SIT9005ACT2G-XXEI uses a pulse-width modulation system to generate an oscillating signal with a precise frequency and duty cycle. This system consists of an adjustable-frequency clock signal generator and an output stage, which controls the output waveform of the oscillator. The adjustable-frequency clock signal generator is fed by an external oscillator, such as a crystal oscillator, and consists of two components—a divider and a programmable register. The divider is responsible for frequency division, which generates the oscillator’s clock output at a certain frequency. The programmable register stores the frequency configuration data and can be used to adjust the output frequency of the oscillator. The duration of the output waveform is controlled by the output stage, which enables the oscillator to generate multiple waveforms. The output stage can be programmed for any duration, allowing for flexibility in the output signal.

In addition to the pulse-width modulation system, the SIT9005ACT2G-XXEI includes several other features that improve its accuracy and performance. These include a temperature compensation module, an inertial drift correction module, and a lock-in adjustment feature. The temperature compensation module adjusts the output signal of the oscillator to account for environmental temperature changes. The inertial drift correction module adjusts the drift of the output signal, avoiding long term error accumulation. The lock-in adjustment feature allows for precise control of the output signal, eliminating any frequency jitter. These features enable the SIT9005ACT2G-XXEI to achieve excellent frequency accuracy over a wide temperature range and reduce the jitter in output signals.These features make the SIT9005ACT2G-XXEI an ideal choice for applications that require accurate timing control. Its wide range of output configurations, adjustable input clock frequency, adjustable edges, adjustable phase offset, temperature compensation module, inertial drift correction module, and lock-in adjustment feature make it suitable for a variety of applications, ranging from RF clock recovery to crystal oscillator designs.
