LTC4300-1允许用户将I/O卡插入带电的背板而不会对2线系统的SDA和SCL信号造成破坏。而连接电路了双向缓冲，保证背板和卡之间的电容隔离。上升时间加速电路可提供额外的性能以满足上升时间的要求。advertisementHotSwapandBufferI2CBusesDesignNote263JohnZieglerAsserversystemshavegrown,thenumberandcomplex-AftergroundandVCCconnect,SDAINandSCLINmakeityofinput/output(I/O)cardsthatcontaincontrolcircuitryconnectionwiththebackplaneSDAandSCLlines.Duringtomonitortheservershavegrowninproportion.Zerothistime,the1VprechargecircuitryisactiveandforcesdowntimesystemsrequireuserstoinsertI/Ocardsinto1Vthrough100knominalresistorstothelowcapacitancealivebackplane.WhilemanyICvendorshavedeveloped……

为提高系统在大量数据处理、数据存储和通信系统的稳定性，子系统中包含一些主动电路来监控系统中的一些参数，如温度、风扇速度和系统电压等。独立的子监控系统一般通过2线串行总线如SMBUS、I2C与主机通信。随着监控功能复杂度和数量的增加，一些实际问题也开始显现。如数据总线上升时间特性无法满足，不间断系统无法适应新I/O卡及器件的地址一般为专用等。LTC4302-1/LTC4302-2可寻址2线总线缓冲器可解决所有这些问题。advertisementAddressableI2CBusBufferProvidesCapacitanceBuffering,LiveInsertionandNestedAddressingin2-WireBusSystemsDesignNote329JohnZieglerIntroductionLiveInsertionandRemovalandInanefforttoimprovethereliabilityoflargedataprocess-CapacitanceBufferingApplicationing,datastorageandcommunicationssystems,theirTheLTC4302solvesbusconnect/disconnectproblemssubsystemsincludeagrowingnumberofactivecircuitsbycreatinganactivebridgebetweentwophysicallysepa-tomonitorparameterssuchastemperature,fanspeedrate2-wirebusses.TheLTC4302’stwo“input”pin……
