Working Principle

The PI49FCT3802QEX works by receiving an input clock signal which is then distributed to its output pins. Once the input clock has been received, the programmable clock generator built-in to the device processes the input clock and generates an output clock with the desired characteristics. This output clock can then be used to synchronize multiple data streams or devices. The clock generator can also be programmed to have different skew and delay values for each output, providing flexibility to the user.

In addition to its programmable clock generator, the PI49FCT3802QEX also features an integrated PLL which allows it to accurately lock up to the input clock and ensure data integrity. The integrated PLL also helps to reduce jitter and ensures that the output clock is of the highest accuracy and reliability, which is essential for many high-speed applications.

Conclusion

The PI49FCT3802QEX is a highly efficient and cost-effective device designed for low-power clock distribution and synchronization over high-speed busses and networks. With its integrated PLL, programmable clock generator, and adjustable skew and delay, it can provide a reliable and accurate output clock for many demanding applications, making it an ideal choice for industrial, computer, and telecommunications markets.
