For more experience sharing, follow RF Engineer When a microcontroller or FPGA sends SPI control signals to a phase-locked loop chip, it often requires a series connection of a 22 ohm or 33 ohm resistor. What is the reason for this? Impedance discontinuities can cause electromagnetic wave reflections, which in turn lead to signal distortion. … Read more

This article comes from the disassembly activity of the Breadboard Community! Rich rewards! (Two DJI drones, two oscilloscopes, etc.)! Electronic engineers hurry up and participate!👇 I have an older 100M logic analyzer that I bought a while ago. Its parameters were quite high at that time, with sampling rates of 100/50/32/16MHz for 3/6/9/16 channels, using … Read more
1 Reasons Driving Change in FPGA Debugging Technology The reprogramming capability of FPGAs is a key advantage in the functional debugging of hardware designs. In the early days of using CPLDs and FPGAs, when a design was found to be malfunctioning, engineers would use the “debug hook” method. They would route the internal signals of … Read more
Welcome FPGA engineers to join the official WeChat technical group. This article mainly introduces the structure, external interfaces, and operations of NOR Flash. In NOR Flash, the ‘N’ stands for NOT, meaning that when there is a charge in the Floating Gate, it reads ‘0’, and when there is no charge, it reads ‘1’. This … Read more
