Working Principle

The PI6C2409-1HWIEX utilizes the principle of frequency synthesis through the use of phase-locked loops (PLLs). In frequency synthesis, two signals with different frequencies are input into a feedback loop and transmitted through a mixer or a frequency translator to generate a new frequency. The main clock reference signal is typically generated by a crystal oscillator, which provides a single frequency. The output frequency is generated by mixing the reference frequency with a variable frequency, typically using a voltage controlled oscillator (VCO). The output frequency is then further divided and filtered to create a clock output.

The PI6C2409-1HWIEX utilizes PLLs to multiply or divide the frequency of the clock output from that of the reference frequency. The PLL operates by generating a loop bandwidth and reference frequency to maintain a stable loop in the frequency synthesis process. The PLL then uses a phase detector to compare the input reference signal of the loop to the generated output frequency. Any discrepancy between the two is used to adjust the frequency of the output until the desired frequency is generated.

The PI6C2409-1HWIEX also uses a digital clock generator with an integrated voltage-controlled oscillator (VCO). The digital clock generator and VCO are used to control the output frequency of the system. The VCO is used to adjust the output frequency while the digital clock generator is used to program the output frequency. The digital clock generator features integrated register control of multiple output frequencies and a selectable spread spectrum control option to reduce EMI noise.
