Working Principle

The SI5350A-B02814-GT is a clock generator module based on a fractional-N Delta-Sigma PLL (Phase Locked Loop) architecture. It utilizes a high stability oscillator as its reference frequency source with a frequency range from 2.5 to 27MHz. The internal PLL modulates the reference frequency to obtain a wide range of output frequencies that are based on the selected reference frequency. By utilizing the same reference frequency, multiple output frequencies can be generated. The generated signal has very low jitter and is suitable for signal de-skewing and jitter attenuation. The PLL is also capable of tracking an external signal, allowing it to be used for frequency synthesis.

The SI5350A-B02814-GT can provide up to eight differential outputs, with each output providing a frequency up to 1GHz. The outputs can be programmed independently to generate various frequencies and phases, allowing multiple clocks to be generated from a single reference source. Each output can also be individually calibrated to ensure even more accurate performance over a wide operating temperature range.

The SI5350A-B02814-GT also has many built-in features to allow for advanced signal processing. It supports integrated spread spectrum, as well as de-emphasis for high-speed signals. It also has an integrated frequency detector for detecting the frequency and level of an input signal. The device is powered by a 3.3V supply and features integrated power saving and power-down modes.

In summary, the SI5350A-B02814-GT is a highly versatile clock generator module that provides superior jitter performance and is capable of generating frequencies up to 1GHz. It is well-suited for a wide range of clock management applications that require enhanced performance but are limited by size and power constraints. It is also capable of tracking an external signal, enabling frequency synthesis, and a wide range of integrated features are included to allow for advanced signal processing.
