The P2180AF-08SR is a clock generator, phase locked loop (PLL), and frequency synthesizer, designed to generate various output frequencies from an input reference clock frequency. It is typically used in telecommunications, data communications, networking, and computer applications.

The P2180AF-08SR combines all the functions of a clock generator, PLL, and frequency synthesizer. It contains an integrated phase-locked loop that can lock the output frequency to a reference clock frequency for superior jitter performance. It is capable of generating frequencies from 2 to 800 MHz, depending on the input reference frequency. It has a wide operating temperature range from -55℃ to +125℃.

The P2180AF-08SR also provides many advanced features for quick and easy customization of the system clock frequency. Some of these features include pre-programmed operating frequency selections, fine-tune frequency adjustments, low jitter performance, and on chip delay tuning. It also has an integrated PLL, which allows the user to set the frequencies using a set of resistors and capacitors.

The P2180AF-08SR can be used to generate various output clock frequencies, such as to provide timing reference clocks for metro Ethernet, SONET/SDH, GPS, IEEE 1588, and other emerging communications applications. It is also suitable for data communications and computer applications, such as synchronization of different clocks within a system, generating various frequencies needed for various communication protocols. It can also be used to generate a frequency needed for testing, or for system identification or diagnostics.

The working principle of the P2180AF-08SR is based on the input reference clock frequency. It uses an on-chip loop filter and VCO to generate an output frequency, which is then divided by a counter to produce the desired output frequencies. The loop filter uses the resistors and capacitor to determine the loop bandwidth, which is used to determine the frequency accuracy, jitter performance, and on-chip delay tuning. The VCO is then used to generate the desired output frequency using a set of dividers. If a higher resolution output frequency is required, additional dividers can be added to increase the resolution.

The P2180AF-08SR is an ideal choice for any system requiring an output clock frequency that is accurate, low jitter, and easy to customize. It is a highly integrated part with advanced features for quick and easy customization, making it a great choice for any application requiring an accurate, reliable frequency generator. It is also highly reliable and is capable of operating over an extended temperature range, making it an ideal solution for mission-critical applications.
