时钟扇出缓冲器,8T39204,Renesas 时钟扇出缓冲器,8T39204,Renesas 时钟扇出缓冲器,8T39204,Renesas 时钟扇出缓冲器,8T39204,Renesas

IDT(RENESAS收购)推出的高性能时钟扇出缓冲器,以8T39204为例, 输入时钟可以从两个差分输入或一个晶体输入中选择。如果未选择晶振输入,则内部振荡器电路将自动禁用。 晶体引脚可以由单端时钟驱动。所选信号分配到四个差分输出,可以配置为LVPECL,LVDS或HSCL输出。此外,还提供了LVCMOS输出。可以将所有输出禁用为高阻抗状态。该器件设计用于高频、低相位噪声时钟和数据信号的信号扇出。输入断开或接地时,输出处于定义的电平。 它设计为使用3.3V或2.5V内核电源以及3.3V或2.5V输出工作电源供电。

本文分享时钟扇出缓冲器8T39204的驱动器和接收器两种端接参考设计。


对于驱动器和接收器将在单独的PCB上(板间)的应用,建议使用图1的端接。此终端是PCI Express™和HCSL输出类型的标准配置。 所有走线应为50Ω阻抗单端或100Ω差分。

图1 驱动器和接收器位于单独的PCB板的设计示例


对于可以使用点对点连接的应用,建议使用图2的端接。点对点连接在同一PCB上包含驱动器和接收器。 通过在接收器处匹配的端接,可以将传输线反射最小化。此外,驱动器上的串联电阻(Rs)具有灵活性,可以帮助抑制不必要的反射。可选电阻器的范围为0Ω至33Ω。所有走线应为50Ω阻抗单端或100Ω差分。

【产品】两对差分参考时钟输入对的时钟扇出缓冲器8T39S11A,晶振输入可接受10MHz至40MHz晶振或单端时钟

8T39S11A是IDT(Renesas收购)推出的一款高性能时钟扇出缓冲器,可用于高频低相位噪声时钟和数据信号的信号扇出。其输入时钟可从两个差分输入或一个晶振输入中选择。如果未选择晶振输入,则缓冲器内部振荡器电路将自动禁用。晶振引脚可以由单端时钟驱动。所选信号分配到十个差分输出,这些输出可以配置为LVPECL、LVDS、HSCL输出和LVCMOS输出。所有输出均可被禁用为高阻抗状态。
