PCB Design Techniques will look at the comparison of DDR2 to DDR3; DDR3 design guidelines; pre-layout analysis; critical placement; an example of design rules; and finally, the post-layout analysis.

For configuration of the DDR interface, refer to the TMS320TCI648x DSP DDR2 Memory Controller User's. Guide (SPRU894). 2. Implementing DDR2 PCB Layout on
LPDDR2 is fastest in mobile DRAM, and PCB design guidelines is written to use LPDDR2 signals. These guidelines cover Mobile SDR/DDR as well as LPDDR2. 2. PCB Design Guidelines for Signals. If one Mobile DRAM (1-package & 1-/CS) is designed in PCB, all topologies are same as. “Point to Point" for all signals (DQ
DDR allows two data bit transitions to occur during a single clock cycle, instead of a single data bit transition—as previously in Single Data Rate (SDR) memory—effectively doubling its data throughput. The increased speed of these memory circuits has made the complexity of the PCB layout more demanding with respect to
28 Jul 2009 DDR Interface. DDR interface with its requirements of small setup and hold times, clean power and reference voltages, tight trace matching and I/O (SSTL-2) signaling presents the board designer with great challenge. It is recommended the DDR layout to be supervised by a senior design engineer with
I am designing a PCB with Artix and DDR2 (eventually DDR3). I found a number of application notes on how to layout the PCB, watch out for impedance, EMI and sI, etc but I haven't found a clearly defined whole set of length match rules. Is there such thing? Out of my desperation I had a look at the SP605 gerber files and
