Virtex-6 FPGA Integrated Block Wrapper v1.7 for PCI Express - What is the PMA_RX_CFG setting for an asychronous link?

描述

What is the best setting for the GTX attributePMA_RX_CFG for an asynchronous link?

解决方案

For asynchronous links, meaning that each link partner is clocked by a different oscillator, the recommended value for PMA_RX_CFG is 25'h05CE049. Set this value in the file calledgtx_wrapper_v6.v[hd] in the generated core's source directory.For more information regarding clocking and PCI Express, see (Xilinx Answer 18329).
