Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers

The PI6C22409WIE is a programmable, multi-output clock generator IC (integrated circuit) that features an exceptionally wide frequency range of 1– 1152 MHz. It includes a total of nine outputs, each with its own independent programming capability; this allows for great flexibility in multiple output applications as well as optimized clock designs. The PI6C22409WIE is in a standard PLL (phase locked loop) architecture, with a source programmable from 4 kHz to 4 MHz. The output frequency of each of the 9 output dividers is programmed with 2×4 switches, giving a range of 1– 1152 MHz.

Application Field

The PI6C22409WIE can be used in a variety of applications, ranging from industrial controllers to consumer electronics. Most notably, its versatility makes it suitable for use in multiple output applications, such as in systems which require synchronized clock output frequencies. The wide frequency range and high programmability allow for efficient frequency division, allowing for greater synchronization between a system’s clock outputs. It can also be used in conjunction with an external frequency source for optimal clock synchronization.

Working Principle

The PI6C22409WIE uses a Phase Locked Loop (PLL) architecture to generate its nine independent output frequencies. The IC’s internal oscillator is connected to a series of dividers, each adjusting the output frequency according to the frequency division required. The dividers are programmable with a 2×4 switch, allowing the output frequencies of each of the nine outputs to be adjusted. The resulting nine output frequencies are in turn connected to a series of buffers to ensure that they are stable and accurate.

To ensure optimal operation of the IC, it is important to select the correct input frequency and division parameters as required by the system. The external frequency source, if used, must also be properly matched to the output division parameters for optimal frequency division. Once the desired frequencies have been programmed and the IC is powered on, the nine outputs will synchronize to the programmed division parameters, providing the required output frequencies.

The PI6C22409WIE is also capable of self-testing its outputs and reporting any errors, allowing for quick diagnosis and remedial action if any issues arise. This makes the IC even more versatile, as it can be integrated into various systems from industrial controllers to consumer electronics with minimal effort.

Conclusion

The PI6C22409WIE is a versatile, multi-output clock generator IC that offers an exceptionally wide frequency range and high programmability. It utilizes a PLL architecture to generate its nine independent output frequencies, and can be used in a variety of applications, ranging from industrial controllers to consumer electronics. Through efficient frequency division, the IC is able to accurately synchronize the output frequencies of each of its nine outputs, making it ideal for multiple output applications. This high level of flexibility and programmability make the PI6C22409WIE an ideal choice for applications requiring a wide range of output frequencies.
