4.2.10. Programmable Bandwidth

The PLL bandwidth is the measure of the PLL’s ability to track the input clock and its associated jitter. The Intel® Cyclone® 10 LP PLLs provide advanced control of the PLL bandwidth using the programmable characteristics of the PLL loop, including loop filter and charge pump. The closed-loop gain 3-dB frequency in the PLL determines the PLL bandwidth. The bandwidth is approximately the unity gain point for open loop PLL response.
