Working Principles

The LTC6946IUFD-3 utilizes a fractional-N PLL architecture to generate precise frequencies. It consists of a phase detector, charge pump, loop filter, and VCO. The phase detector compares the output frequency with a reference frequency and generates an error signal. This error signal is then filtered and used to control the VCO, which adjusts its frequency accordingly. By continuously adjusting the VCO frequency, the LTC6946IUFD-3 achieves accurate and stable output frequencies.
