The P5I2309AF-116SR is a highly integrated device designed to serve as an essential component in high-end electronic systems. It belongs to a product series of Clock/Timing - Clock Generators, PLLs and Frequency Synthesizers.

This device enables regulation and shorter circuit board foot print by providing a zero-delay single-ended clock Generator with a programmable, highly accurate, low jitter clock reference and timing functions with minimal external components. It integrates output dividers and programmable dividers with automatic locking. Optional up/down counters on the device offer flexibility in frequency-arm length ratio of up to 1/256.The P5I2309AF-116SR also integrates Phase-Locked Loop (PLL) features such as Reference Source Selection logic, VCO and RX dividers, PFD and CP dividers, Loop Filter, Charge Pump and internal Clock Synthesizer.

The integrated reference source selector provides the possibility of selecting among three programmable, low frequency oscillators that generate complete frequency references. If standard oscillators are not needed, the P5I2309AF-116SR can be programmed to operate in 3rd-party clocked Mode (no external reference).All output dividers can be programmed for a variety of ratios and the divider can be configured independently for each output. By using output dividers, the device is able to provide dividers from 1/2 to 256 in increments of 1/256. The programmable dividers will increase the frequency-arm length accuracy of the PLL.

In addition to the Reference Source Selection logic, The P5I2309AF-116SR integrates a VCO that supports any frequency of choice within the range of 5MHz to 300MHz. It also supports a Synthesis mode which enables the device to produce a wide range of output frequencies with a maximum resolution of up to 1/256.The PLL of the device also includes an RX Divider which controls the frequency of the synthesized output as well as a Phase Frequency Detector (PFD) and Charge Pump (CP) that allows for accurate frequency tracking of even highly varying input frequencies. The control loop used by the PLL to maintain the desired frequency output is mounted internally, automatically taking the necessary control actions to ensure the desired frequency is maintained for the selected output. The P5I2309AF-116SR also includes an internal loop filter that is able to offer a high degree of programmability and thus helps to allow the control loop to respond appropriately to the feedback signal.

The P5I2309AF-116SR has a wide variety of applications in large-scale commercial, industrial and military systems. Its precise frequency synthesis capabilities enable it to produce precise and low jitter signals for precise timing and synchronization of communications, navigation and sensing systems used in various applications. The device also has applications in areas such as Video and Audio/Visual systems, DDR memory systems and as a source for precise stimulus signals in test and measurement applications.

In summary, the P5I2309AF-116SR is an essential component for a wide range of applications due to its highly integrated and precise clock reference and timing capabilities. Its Reference Source Selection logic enables the device to not only produce precise and low jitter signals, but also to reduce the amount of external components needed. By integrating output dividers and a programmable divider, the Frequency Synthesizer of the device can also achieve a frequency-arm length ratio of up to 1/256. The device also includes a PLL with RX dividers, PFD and CP dividers, a Loop Filter and an internal Clock Synthesizer all of which are essential components of the device, allowing it to provide precise frequency synthesization and control. The applications of the P5I2309AF-116SR in various industries make it a critical component for many complex digital systems.
