[PDF] Jacinto 7 LPDDR4 Board Design and Layout Guidelines (Rev. F): Expert Tips! High current pcb layout guidelines
Ah, so you want to design a PCB for external memory, eh? Very good, very good. It's not just about slapping down components and hoping for the best. Need some discipline, some finesse, like perfecting the art of calligraphy. A sloppy layout? That's like writing with a blunt brush! Let’s see what we can do, shall we?
First, the Write Leveling – It's Crucial!
Okay, okay, pay close attention now. Write leveling in your DDR memory is important. It’s like balancing a stack of delicate porcelain teacups. If one is off, the whole thing comes crashing down! So, what is write leveling? It’s making sure the data arrives at the memory chips at the right time, no early, no late. Imagine a group of people trying to clap in unison, some are too eager and clap ahead of everyone else, some are slow and clap late. It's a mess! Write leveling aligns everything. The signals must be precisely timed so the data is written correctly. Consider trace lengths! Longer traces introduce delays. Make sure your signals traveling to the memory devices are matched in length. You want symmetry, like a well-balanced bonsai tree. Don’t cut corners here, use software to help you calculate the delays, and simulate the performance. Think of it as meticulously planning a complex tea ceremony – everything must be perfect.
Now, the PCB Design Rules and Tips – Golden Rules, Follow Them!
These rules, they are not just suggestions, you know? They are the foundation, the bedrock, upon which your successful PCB is built! Think of it like the secret family recipe for the perfect dumplings. If you skip an ingredient, the whole flavor is ruined! Consider your power and ground planes. These are essential. They are like the strong, steady roots of a tree, providing nourishment and stability. Use solid, unbroken planes. Minimize the number of vias that disrupt the planes. Vias, they can be necessary, but they also introduce impedance discontinuities, like pebbles in a smooth stream. And impedance matching! This is paramount. You want to make sure the impedance of your traces matches the impedance of the memory and the controller. Reflections, oh, those are nasty! They can corrupt your signals and lead to all sorts of problems. Treat them like unwelcome guests. Terminate the traces properly to prevent reflections. Also, routing! Keep your traces short and direct. Avoid sharp bends. Think of it like a smooth, flowing river. Sharp bends create turbulence and disrupt the flow. Route your differential pairs close together. They are like a pair of chopsticks, working together in perfect harmony. Shield sensitive signals. Protect them from noise and interference. Imagine you are wrapping delicate treasures in silk cloth to keep them safe. Finally, decoupling capacitors! Use plenty of them. Place them close to the memory chips. They provide local charge storage and help to reduce noise on the power rails. They are like little batteries, always ready to supply power when needed. Remember all these points, and your PCB design will be a masterpiece! Like a perfectly brewed cup of jasmine tea.
