在实现10GBASE-R、采用IEEE 1588v2的10GBASE-R或具有FEC的10GBASE-R收发器配置规则之前,应先熟悉10GBASE-R和PMA体系结构、PLL体系结构和复位控制器。 必须在FPGA中设计自己的MAC和其他层,以使用Native PHY IP实现10GBASE-R、采用1588的10GBASE-R或采用KR FEC的10GBASE-R收发器配置规则。 从IP Catal...
The KR FEC TX gearbox aligns with the FEC block. Because the encoder output (also the scrambler output) has its unique word size pattern, the gearbox is specially designed to handle that pattern. 10GBASE-R with KR-FEC Intel® Stratix® 10 10GBASE-R具有同样针对10GBASE-KR PHY的可选FEC...
对于10GBASE-R与10GBASE-KR，Intel® Stratix® 10提供可选FEC种类，以提高链路预算与BER性能，尤其针对更多背板通道定义。此FEC提供了额外的裕量，考虑了制造与环境条件的变化。TX与RX FEC子层分别位于PCS与PMA子层之间，用于10GBASE-R与10GBASE-KR物理层。图124与125展示了支持10GBASE-R...
Include FEC sublayerOn/OffWhen you turn this optionOn, the core includes logic to implement FEC and a soft 10GBASE-R PCS. SetFEC_abilitybit on power up and resetOn/OffWhen you turn this optionOn, the core sets the FEC ability bit on power up and reset. ...
10G/25Gbps 以太网PCS, KR4 FEC 和 MAC IP 核 Precise-ITC IP核符合IEEE 802.3标准并且完全集成了应用于25Gbps以太网的物理编码子层(PCS), KR4 FEC和媒介存取控制(MAC)。PMA接口支持单个10G/25Gbps双向串行接口。PCS子层包括66B编码,转码和加扰。这IP核还支持可通过软件寄存器配置的CPRI-8,9和10PCS模式。
The fully integrated Physical Coding Sublayer (PCS), KR4 FEC and Media Access Controller (MAC) core for 25Gbps Ethernet applications are compliant with IEEE 802.3by standard. The interface to the PMA supports a single 10G/25Gbps bi-directional, serial interface. The PCS sublayer includes 66B ...
10GBASE-R和10GBASE-KR的物理层包含一个KR FEC子层,位于PCS和PMA子层之间。这个KR FEC子层为10GBASE-R物理层的PCS和PMA子层之间的接口提供代码增益,以提高链路预算和BER性能,特别是对于需要考虑制造和环境条件变化的更多背板通道。TX FEC子层和RX FEC子层分别位于10GBASE-R与KR-FEC协议中。TX FEC子层用于...
Next, in Figure 58, we see a case with FEC support (which I don't use, but it's interesting anyway) and 64b PCS/PMA interface (so parallel clock is 161.13MHz). FPGA-side of FIFOs is still 156.25MHz and diagram shows that we can either supply our own clock to rx_coreclkin...
IEEE10GBase-ROTN 中国铁通集团有限公司程华 对10GBase-R信号的传送有两种需求即MAC层透明传送和PCS层透明传送。MAC 层的透明传送使用现存的标准可以实现,但PCS层的透明传送需要新的标准。本文描述了 10GBase-R信号在SDH和OTN传送网上传送的几种标准的和非标准的方法,并比较了几 种方法的特征。 10GBase-R、10GBAS...
If auto-negotiation is disabled and Base-R FEC is enabled on the remote port, the local port supports only the QSFP-4SFP25G-CU3M high-speed cable. When the port works in 4*10GE mode, it can use: QSFP+ optical module and MPO-4*DLC or MPO-8*FC optical fiber QSFP+ to 4*SFP+ hi...
