Working Principle

The CY22393ZC-519 uses a phase locked loop (PLL) architecture to generate its clock outputs. PLLs are electronic circuits that are used to generate precise clock signals from a reference clock signal. In a PLL system, an input signal is multiplied by an adjustable frequency divider until its frequency matches the desired output frequency.

The CY22393ZC-519 uses an advanced digitally controlled oscillator (DCO) to generate its outputs. This DCO can be tuned to generate precise output frequencies by adjusting the control word. The device also features a programmable loop filter that can be used to tune the loop filtering, resulting in better jitter performance.

The CY22393ZC-519 also has an digital-to-analog converter (DAC) to adjust the output gain, as well as a programmable reference divider to adjust the reference frequency. It also has a low-noise voltage-controlled oscillator (VCO), which can be used to generate very low-jitter frequency signals.
