290PGILF

Phase-locked loop frequency synthesis, also known as PLL frequency synthesis, is widely used in modern telecommunications and broadcast systems due to its ability generate reliable, continuously tunable and precisely controlled RF frequencies. This technology enables the rapid, low-cost production of multiple and widely distributed frequency signals. PLL consists of a stable reference oscillator, comparator, and internal low pass filter circuits integrated into the same package, allowing it to lock onto the reference frequency and to maintain therequired RF frequency stability over a wide range of environmental conditions with optimal performance.

PLLs enable high frequency resolution by systematically bypassing the sample parameters of their internal oscillator. This method gradually adjusts the amplitude or frequency of the generated output signal as the incoming reference frequency is varied. As a result, PLL generated signals have a wider spectral range and higher frequency accuracy (<4.5ppm for all conditions) than those produced by other methods such as generic frequency dividers.

Phase-locked loops are a key component in any modern communication system. For example, mobile phone service providers rely on them to generate the correct frequencies for each phone conversation. Likewise, satellite communications may use numerous PLLs in their systems to provide signals that are extremely accurate and reliable. As an added benefit, most PLLs are software programmable and can be configured to different operating parameters dynamically.

In addition to providing frequency protection, PLLs offer significant advantages when it comes to maintaining reliable, continuous RF frequency control. Not only can they provide predictable, stable output signals throughout widely varying environmental conditions, they can also adjust their response times quickly enough to meet the requirements of any rapidly changing workload.

Furthermore, the integrated comparator and lowpass filter circuitry in PLLs enable accurate and reliable data conversion with minimal errors. This design, in which the comparator continually measures and compensates for any discrepancies between the incoming reference frequency and the generated output signal, makes PLLs incredibly resilient to external noise sources.

Overall, the 290PGILF PLL is a powerful and highly reliable frequency synthesizer. This product provides a range of features designed to meet the needs of any communication system. With its frequency accuracy, extended temperature range, high immunity to noise sources, and software programmable configuration parameters, the 290PGILF enables customers to create reliable, long-term frequency sources that meet the exact needs of their application.
