在实现上,10GBASE-KR通常与XGMII接口配合使用,实现MAC层串行数据和XGMII接口并行数据之间的转换。XGMII接口支持全双工操作,具有固定的数据信号、控制信号和时钟信号配置。 前向纠错功能(FEC): 10GBASE-KR支持FEC功能,该功能通过提供编码增益的方式实现提高链路预算能力和BER性能。FEC子层在PCS和PMA层之间工作,通过编码/...
10GBASE-KR (C72) BASE-R FEC(C74) FEC指的是前向纠错功能(forward error correction)功能。FEC的工作层次在PCS和PMA层之间。FEC功能通过提供编码增益的方式实现提高链路预算能力和BER性能。 发送方向:FEC子层从PCS子层接收数据,对66B/65B(先去掉两比特同步头,再添加一比特T头)代码转换,执行FEC编码/成帧,最后...
The 10 Gigabit Ethernet PCS/PMA (10GBASE-KR) is a LogiCORE which has an optional FEC (forward error correction) and/or auto-negotiation protocol and link training allowing ultimate flexibility in your solution.
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...
1)CPRI支持10GBASE-KR。 2)CPRI的电气特性和10GBASE-KR一样,10GBASE-KR实际是指出了所用的介质(背板),也唯一地确定了CPRI的电气特性。 3)CPRI借用了10GBASE-KR的分层结构,但PCS和FEC的实现上与10GBASE-KR有差异,因此CPRI实际是指CPRI协议。 若有误欢迎一起讨论~ ...

10GBASER：这是10Gbps以太网的一种物理层规范，支持使用XGMII接口连接具有64B/66B PCS编码的协调子层。它可能包含可选的前向纠错等技术，以提高链路预算和误码率性能。10GBASEKR：这是专门为电气背板应用设计的10Gbps以太网物理层规范。它同样支持64B/66B PCS编码，并可能包含KR FEC子层，以提供代码...
The 10 Gbps backplane ethernet 10GBASE-KR implementation uses the XGMII interface to connect to the reconciliation sublayer (RS) with 64B/66B PCS encoding, the optional Forward Error Correction (FEC), and Auto-Negotiation (AN) support to the Highest Common Denominator (HCD) technology with the...
