Abstract

The Common Switch Interface Specification (CSIX) defines a physical interface for transferring information between a traffic manager (also named Network Processor or Protocol Engine) and a switching fabric. From a hardware standpoint the CSIX physical interface defines two modes of operation, each of them having the following bus characteristics: LVCMOS mode: the bus is 280-bit wide made of: 128 transmit data signals split into four groups: G0_TxD(31..0),
