大家有用PX1011A实现PCI-E的吗？

今日电子2005年地八期 刊登：
Phi l i ps  PX1 01   1 A PHY 结 合
i l i n x   S p a r t a n -3  F P GA ( 带有一个优化的 I   P核)可提供速度达 2． 5～  8 0 Gb ／ s 速率的PC I   E 终端解决方案， 成 本不到1   5 美元， 大大低于传统方案。
我看这个方案比用V5 V6实现起来要便宜的多，大家有对这个方案了解的吗？当时刊登的联系方式 电话 网站都不存在了（应该是被恩智浦收购的缘故），

在恩智浦网站看 只能实现X1结构 通信速率只能达到2.5Gbps

PCI Express is a high-speed, point-to-point serial connection that offers a 2.5 to 80 Gigabit transfer rate. It has a dedicated link to each device instead of a shared bus, and delivers advanced features with scalable performance that gives manufacturers the flexibility needed to quickly bring PC, peripheral and consumer electronic products to market.



Comprised of the Philips PX1011A PCI Express PHY and a Xilinx Spartan™-3-based FPGA with an optimised Xilinx PCI Express LogiCORE IP™ core, the flexible Philips-Xilinx PCI Express offering can be used in many high-volume applications including add-in cards, host bus adapters, graphics cards and high-end servers. The PCI Express solution is also packaged in a low-profile form factor, supporting ExpressCard technology applications for space-constrained modular expansion platforms, and it is fully compliant to the PCI Express 1.0a specification.

这是恩智浦的原话 应该是今日电子翻译错误 只能实现2.5Gbp的通信速率

太深奥了...

从你发的英文原文来看,2.5G到80G传输速率的是PCI Express本身,没有提到这个方案实际能多高吧

The PX1011A/PX1012A is a high-performance, low-power, single-lane PCI Express
electrical PHYsical layer (PHY) that handles the low level PCI Express protocol and
signaling. The PX1011A/1012A PCI Express PHY is compliant to the PCI Express Base
Specification, Rev. 1.0a, and Rev. 1.1. The PX1011A/1012A includes features such as
clock and data recovery (CDR), data serialization and de-serialization, 8b/10b encoding,
analog buffers, elastic buffer and receiver detection, and provides superior performance to
the Media Access Control (MAC) layer devices.
