Working Principle

The SI5335B-B02252-GMR is an advanced frequency synthesizer and clock generator device that can generate low-jitter clock signals across a wide frequency range. It utilizes a combination of a phase-locked loop (PLL) and a voltage-controlled oscillator (VCO) to generate the desired frequency. The PLL is a digital circuit constructed of a reference oscillator, phase comparator, filter, and voltage-controlled oscillator (VCO). The reference oscillator is used to provide a basic frequency from which all other frequencies are derived and the filter determines the magnitude of the frequency-locking range. Both the reference oscillator and the PLL filter are programmable and can be configured for different frequencies and bandwidths. The VCO takes the reference oscillator output and output of the filter and generates an output frequency that is locked to the reference frequency. The frequency can then be adjusted by altering the voltage that is applied to the VCO.

The output signals of the device are adjustable on the device itself, allowing output signals to be adjusted to either 50-ohm impedance or TTL levels. The device also has an I2C serial programming interface making it easy to adjust the parameters of the device.
