DS80PCI402是一款低功耗,4通道中继器,具有4级输入均衡功能,以及输出去加重驱动器,可增强PCI的覆盖范围 - 在板对板或电缆互连中快速串行链路。该器件非常适合x4(或更低)PCI-Express配置,并可自动检测并适应Gen-1,Gen-2和Gen-3数据速率,以便于系统升级。
DS80PCI402提供可编程发送去加重(最高12 dB),发送VOD(最高1300 mVp-p)和接收均衡(最高36 dB),以便在有损铜缆(10米或更长)或背板中实现更长距离传输(40英寸或更大)带有多个连接器。接收器可以打开由于互连介质引入的符号间干扰(ISI)而完全关闭的输入眼。
可通过引脚或软件轻松应用可编程设置(SMBus /I 2 C),或者可以通过外部EEPROM加载。在EEPROM模式下工作时,配置信息会在上电时自动加载,无需外部微处理器或软件驱动程序。
