The device is also capable of automatically configuring itself for the desired output clock type and frequency by programming the serial communication interface.

Working Principle:

The SI5344H-C-GMR is a frequency synthesizer that uses patented Phase-Locked Loop (PLL) technology to generate a clock output with low jitter and a low-noise, spread-spectrum-compatible clock. The PLL includes a reference oscillator, an internal digitally-controlled oscillator (DCO), a frequency divider, a phase comparator, a loop filter and a feedback amplifier. The reference oscillator provides a stable reference frequency that drives the DCO, and the feedback amplifier monitors the DCO output and adjusts the DCO frequency according to the phase comparator\'s output. The frequency divider sets the output frequency of the PLL according to the user-defined clock output type. The DCO output is filtered, and the filtered signal is used as the clock output.
