The 525R-03ILFT supports a wide frequency range, while providing low jitter to system designs. This frequency synthesizer supports a maximum input frequency of 25MHz to 1000MHz, allowing it to cover a wide range of applications.

Working Principle

The 525R-03ILFT frequency multiplier is designed to produce different frequency outputs, given a single input frequency. This is accomplished through a combination of two process-level block diagrams. The first block diagram is based on a Phase-Locked Loop (PLL) structured with a digital circuit, which locks onto the input frequency and produces the output frequency. The second block diagram is based on a Frequency Division Circuit (FDC), which divides the input frequency by a selectable factor to produce the desired output frequency.

These two diagrams are combined to create a single, self-contained circuit, which allows the 525R-03ILFT to generate any desired output frequency from the single input frequency, irrespective of the input frequency. This makes the 525R-03ILFT an ideal choice for applications requiring high-performance clock synthesis.

Conclusion

The 525R-03ILFT is a high-performance frequency synthesizer designed to provide versatile frequency output options. With its combination of a low jitter PLL and frequency divider, it is perfect for a wide range of clock- and frequency-sensitive applications, such as digital TV, set-top boxes, USB 2.0 devices, and industrial control systems. The 525R-03ILFT enables designers to create industry-standard timing solutions with an easy-to-use and highly reliable component.
