Can Xilinx FPGA General IO Be Directly Connected to PLL as Clock Input?

[Conclusion] General IO cannot be directly used as a clock input for PLL; dedicated clock pins can be used instead. General IO can be connected to the PLL clock input through a BUFG, but the PLL settings must be modified to select “No Buffer” for the input clock option. The specific internal layout can be … Read more

Usage Record of MIPI CSI-2 TX Subsystem (2.2)

Recently, while debugging an FPGA for video capture and playback, I utilized the MIPI CSI-2 TX Subsystem (2.2) IP. Debugging this board was quite challenging, and I encountered numerous pitfalls, especially since it was my first time working with video interfaces and I was unable to identify the issues. I will document the problems encountered … Read more
