Working Principle

The ADF4112BRU is a frequency synthesizer formed by three main building blocks: oscillator, VCO and PLL. The oscillator block generates a signal with a frequency of Fosc, which is then sent to the voltage controlled oscillator (VCO) block. This oscillator frequency is then adjusted according to the PLL feedback signals, resulting in an output frequency of Fout.

The PLL is the main block of this frequency synthesizer and it is used to generate the output signal with a frequency of Fout. It consists of three main components: phase detector, charge pump and filter. The phase detector compares the phase difference between the reference signal (Fref) and the feedback signal (Ffb) and sends a corresponding digital signal to the charge pump. The charge pump then adjusts the VCO frequency according to the digital signal, resulting in an output frequency of Fout. The output signal of the charge pump is then filtered by the filter block and the output signal is sent to the output buffer.

The ADF4112BRU includes a wide range of functions and features such as low power consumption, wide frequency range, low jitter, fast lock-time and programmable dividers. It also offers adjustable charge pump current, output frequency control, multiple control voltage pins and programmable control logic.
