Aug 15, 2019 · For DDR3, we care about impedance matching to prevent reflections that can cause glitches on the command or data bits, and we care about delay matching to ensure that the data bits or commmand bits all arrive at the chip before they are latched. When designing a PCB, your main weapon against signal integrity problems is your stackup.

Skipping any of the above steps could have devastating consequences to the data integrity of your workstation, servers and blades. Incorrect PCB stack-up may cause crosstalk issues. Incorrect impedance may cause signal integrity issues. Inadequate power plane designs may cause random ECC errors. A DIMM is more than some DRAMs on a PCB.

Consumer's telecom router achieve to route DDR2 and DDR3 on 4 layers board. I've worked on several routers, not on design phase, but vast majority of this high-volume products use PCB with only 4 layers. Using 6 layers prompt a lot of discussion about cost and you should demonstrate that you really can't do a board with 4 layers. same stackup layer with a space between them (Figure 4). Figure 4: Split planes in printed circuit board designs However, given that signal nets are routed and power shapes are placed on successive stackup layers, it is common to find signal nets traversing the gap between power shapes (Figure 5). Signal nets that traverse gaps in power

PCB Design Techniques for DDR, DDR2 & DDR3 (Part 1) Multilayer PCB Stackup Before starting the PCB design it is impor-tant to plan the PCB stackup. To achieve the best results, the following points need to be taken into account: a) Technology Rules—trace width, clearance—characteristic and differential impedance. b) The Power Distribution ...Stackup In pre-layout simulations it is best to use the stackup that will be used for the PCB. Sometimes the final stackup is not available and one a simulation stackup can be created using the dielectric constant (Er) and the dielectric loss tangent (tanδ) of what will be the target dielectric. The Er only determines the

The PCB stackup the customer used was quite thick with many layers. The layers they used to route the interface happened to be close to the secondary side of the stackup . Interconnect Engineering, Inc. postulated that if BGA footprint via crosstalk was an issue, reducing via parallelism would help the situation. Advanced Design System (ADS) design elements provide additional capabilities to the W2200 ADS Core environment, enabling designers to customize the configuration of ADS to suit their design needs.
