13 Feb 2013 Layout. Guidelines. Routing critical signals to the center pins of a ball grid array (BGA) package can be extremely challenging due to the pad and via density . Kintex-7 FPGAs Data Sheet: DC and Switching Characteristics [Ref 2]. significant change in voltage due to switching activity within the XADC.
30 Jan 2017 Chapter 2: Updated guideline 12 in General Memory Routing Guidelines. Added note after Figure . Chapter 2: In General Memory Routing Guidelines, updated guidelines 10 and 21, and added guidelines Appendix B: Added Zynq UltraScale+ MPSoC Data Sheet: DC and AC Switching. Characteristics
31 Oct 2006 (PCB) layout for a Spartan™-3E FPGA in the FT256 1 mm BGA package. The impact and Fanout. The FT256 BGA package, which has a 1 mm/40 mil BGA ball pitch, follows the manufacturing rules for trace width and space in Table 2. . switching noise of 80 simultaneously switching LVCMOS 3.3V I/Os.
27 Sep 2016 DDR2/DDR3 Low-Cost PCB Design Guidelines for Artix-7 and Spartan-7 FPGAs. Routing Channels are the total number of available routing paths out of the BGA—e.g., (Number of BGA balls on one side –1) ? four sides. Figure 2 shows a sample 5 ? 5 BGA ball out, resulting in a total of sixteen total routing
5 Oct 2017 focuses on layout best practices for high-speed memory design, high-speed SerDes channel design, and power The FPGA device on this board is oriented so that the GTY transceiver BGA balls are in the . against the routing guidelines listed in UltraScale Architecture PCB Design User Guide (UG583).
8. Routing and Layer Stackup. Metric Vs English www.ti.com. Here is one of the most common complaints about moving to fine-pitch BGA package design – use of the metric system. Most designers dislike this simply because all of their familiar rule-of-thumb guidelines are in the English system. Quick test, which is easier to
As Ball Grid Array (BGA) packages become increasingly popular and become more populated across the array with higher pin count and smaller pitch, it is important to understand how they are affected by various board layout techniques. This document provides a brief overview of PCB layout considerations when working
1 Mar 2016 BGA Device Design Rules www.xilinx.com. 6. UG1099 (v1.0) March 1, 2016. Chapter 1: General BGA and PCB Layout Overview. Pitch Size. Pitch size is defined as the distance between consecutive balls on a BGA package, measured from center to center, as shown in Figure 1-1. X-Ref Target - Figure 1-1.
18 Aug 2017 “Recommended PCB Design Rules for BGA Packages" appendix of 7 Series FPGAs. Packaging and Pinout Product Specification User Guide (UG475). Dimensions. The major factors defining the dimensions of the PCB are PCB manufacturing limits, FPGA package geometries, and system compliance.
