Clock Generators, PLLs, Frequency Synthesizers are digital circuit devices used to produce a reliable, accurate output frequency from an input frequency that may vary in time. PLL1700E/2K is a highly integrated, programmable clock generator for consumer, communication, automotive and industrial applications.

PLL1700E/2K gives designers unprecedented flexibility to integrate multiple frequency sources using fully programmable parameters. It comes with a high resolution spread-spectrum modulator that enables excellent EMI performance. It also provides several low power and low jitter innovations, enabling frequency drift of less than 250-fs (0.25ppm).

PLL1700E/2K is extremely versatile, offering multiple switching options and a wide range of input and output frequencies. One of its key features is the Programmable Duration Mode (PDM), which provides programmable output frequencies and duty cycles down to 10 ms interval. It also supports output frequencies up to 330 MHz, making it an ideal choice for high performance applications.

The PLL1700E/2K features a PLL (Phase Locked Loop) circuit that is used to generate frequencies from an external source. It works by comparing the input frequency with an internal reference frequency and providing feedback to ensure that the output frequency is synchronized with the input frequency. This is accomplished by using a voltage-controlled oscillator (VCO) that is controlled by the PLL, which adjusts the VCO’s output frequency until it is synchronized with the input frequency.

The PLL1700E/2K is capable of providing a wide range of input and output frequencies, allowing it to be used for various applications. For example, it can be used to generate frequencies from crystal oscillators used in mobile phones and wireless networks, as well as to control the frequency synthesis process in PLL-based radios and communications systems. Additionally, it can be used to monitor and control clock signals in embedded systems and provide precise clock switching for audio and video applications.

PLL1700E/2K also includes a spread-spectrum modulator that allows fine tuning of the output frequency and signals. This feature is especially useful in applications where EMI is a concern, such as in automotive, medical imaging, and broadcast networks. It can help ensure that the signal is compliant with local frequency regulations, reducing interference and ensuring clear communication.

PLL1700E/2K is an easy-to-use clock generator that offers a wide range of benefits, including high resolution spread-spectrume modulation, programmable duration mode, and wide input and output frequencies. It is an ideal choice for high performance applications, offering users unprecedented flexibility and excellent EMI performance.
