Working Principles

The LTC694IS8-3.3#PBF utilizes a fractional-N frequency synthesis technique to generate precise frequencies. It employs a phase-locked loop (PLL) architecture that divides the input frequency by a programmable integer value (N) and a fractional value derived from an internal sigma-delta modulator. This allows the IC to achieve fine frequency resolution and minimize spurious signals.

The PLL compares the divided frequency with a reference frequency and generates an error signal. This error signal is filtered and used to adjust the voltage-controlled oscillator (VCO) frequency, bringing it into lock with the desired output frequency. The integrated multiplexer allows the selection of different output frequencies.
