高速串行接口协议
The two dominant high-speed chip-to-chip interface protocols for networking applications are XAUI [1] and SPI4.2 [2]. While SPI4.2 offers important advantages in channelization, programmable burst sizes, and per-channel backpressure, the excessive width of the interface limits its scalability, and the source-synchronous nature of the protocol reduces its effective reach. Conversely, XAUI is a narrow 4-lane interface, offers long reach, and suits a variety of implementations: FR4 on PCB, backplanes, and cable. Yet as a packet-based interface it lacks channelization and flow control, restricting it from several applications. And both protocols offer only fixed configurations, limiting the ability of the designer to tailor the interface capacity to the application. This document defines a new protocol, Interlaken, that enables the design of a narrow, high-speed, channelized packet interface.
