Hi, I want to know if a PCB board is only having differential pairs to route and they are routed on top and bottom side of the board, then is it good practice to put two GROUND plane back to back (signal-ground-ground-signal) in PCB stack? If it is not then please suggest the right way to route the board and right stacking of PCB.
Hi All, Is it possible to route differential signals in orcad 9.2 layout. If yes, please tell me how to do in Orcad 9.2 Layout.
I am a bit lost about how to establish the parameters to establish differential pair routing. I am currently trying to route several differential pair and I am a bit new to this. I have searched online some tutorial but I don't find any really explaining **easily and out of the theory** with sipmple (...)
Hi, I already design a LNA schematic and layout, so far so good. Now, I plan to make it as a differential pair LNA... I had some idea about the schematic and test bench, but it does not work very good specially when it comes to layout. Can anybody introduce me the references I can use for finding the structure os schematic and also the test benc
Hi everyone, In my design, I have some special pairs of wires. The two signals in each pair should be totally matching with each other, having the same transmission delay like "differential signals". Is there any commands that I could use as timing constraint or routing options in Encounter? Thanks
Hi every one, In Ethernet protocol routing, where differential pair signal should be routing either top layer or bottom layer? What is the guidelines of Ethernet protocol signals.
Hi, how to calculate the trace width for 80 meter distance transmission line. I am using rs 485 ic, and we split the pcb and join it using board to board connector. Single pcb length is 560mm, total length is 80 meter. Shall i route differential pair routing for AB line.
Hello All, In my design i am using differential pair and i have set all the rules required for the differential pair routing like clearance, matched net lengths, differential pair routing and differential width. Everything is working (...)
Hi Friends, I need to know how to do differential pair arc routing in PADS Router version 9.4? Regards, R.Rajesh Kanna
Is there a autoroute function for differential traces on CADSTAR?
diff net pairs need to end with a "_P" and "_N" extension. Otherwise you need to add them manually. Look for Interactive differential pair and Multi-trace (Bus) routing in Atlium and : "HiSpeedDesignTutorialforAltiumDesigner.pdf"
Hi All, I am new to this membership. i am very glad to see the comments in this website. I too have some doubts, kindly give comments. I am using ARES PCB designer, when I try to route a differential pair there was no option I noticed. Is it possible to do differential pair routing in ARES PCB (...)
Hi, I have been using the higher version of allegro since 2 years so cannot recall properly the menu of 15.7. Check you have routing as menu item , in that you will have something for differential pairs . If you did not get that let me know, I will go back to 15.7 and check that.
I need your help in length tuning a group of nets! Design is a DDR2 board, I am trying to tune each DQS group. Each group contain an 8-bit single ended data lines and a differential pair. Interactive routing and length tuning of single ended section is fine, but the diff pair fails. I used following rule in the "Matched Net (...)
Hi, How to route the speaker interface signal in PCB.Whether i have to route as differential pair or i can go with ordinary signal routing(Signals named as +ve and -ve). help me to do better Regards Rajan.K
read this document which resides in your altium help folder. AP0135 Interactive and differential pair routing.PDF
hi the differential pair routing will help in cancelling out noise impact. so, even if it is analog signal we can use differential pair. i.e., the reason why we usually route the inputs of an op-amp as differential pair. hope this info. helps Regards
hi SL , You can use differential pair routing if you have two nets to be routed with identical length. (Place > differential pair routing)
Yes You can route differential signalsin altium. there is DRC set where you have to define DP and then you can route them
Hi, You cannot use differential pairs in Layout. You can use them only in Capture. The netlist dosn't carry to Layout the information needed. Probably it is possible to work with differntial pairs in Allegro.
