Description

PCI-Express provides for low pin-count, high reliability, and high-speed with data transfer at rates of up to 5.0 Gbps per lane, per direction, and an PCIe module is included on the TI 66AK2Gx DSP + ARM Processor system on chip (SoC).  This PCIe PCB design considerations reference design  helps developers optimize the printed circuit board (PCB) design by providing best-practice PCB for the PCIe portion of the 66AK2Gx Processor SoC.  This in turn enables developers achieve desired PCIe signal performance on the first PCB implementation pass, allowing rapid focus on K2G Processor based application development and test.  The 66AK2Gx General Purpose EVM (EVMK2G) is used as a reference to discuss some of these considerations.

Features
  • Optimized High Speed Signal Routing
  • Surface-Mount PCIe x1 Socket
  • Example of AC Coupling Capacitor Placement
  • Example of Recommended Differential Pair Spacing
