Working Principle

The SI5335D-B02444-GMR uses a fourth-order Phase-Locked Loop (PLL) which utilizes a reference source. The reference source may be an external crystal oscillator or a reference clock which is fedback to the input of the PLL. The PLL then locks its output to the reference frequency, adjusting the feedback frequency and thereby creating a derived output frequency.

The SI5335D-B02444-GMR includes a precise voltage-controlled oscillator (VCO), which is used to produce an oscillating signal whose frequency is adjustable based on a voltage level. The VCO simultaneously provides two outputs which are phase-locked to each other and whose frequency can be adjusted. The outputs of the VCO are connected to the PLL which will set its output frequency as a combination of the VCO output frequencies.

The SI5335D-B02444-GMR also features a comprehensive selection of features to ensure smooth frequency and phase control. The device includes fractional synthesizers, clock multiplication circuitry, a low noise power supply, and programmable loop bandwidth for optimizing jitter and phase noise performance. As a result, the PLL is able to generate a wide range of precision low jitter and low phase noise signals for broadcast and consumer applications.

Conclusion

The SI5335D-B02444-GMR clock generator, frequency synthesizer, and phase locked loop is an ideal solution for various broadcast and consumer applications due to its exceptional flexibility and wide range of features. The device utilizes a fourth-order phase-locked loop to lock the output to a reference clock, allowing it to generate a wide range of precision low jitter and low phase noise signals.
