概览
MC100LVEL14 是一款低歪曲率 1:5 分发芯片，明确适用于低歪曲率时钟分发应用。该器件可由差分或单端 ECL 驱动，如果使用正向电源，则由 PECL 输入信号驱动。LVEL14 可与 EL14 实现的功能和引脚兼容，但设计运行模式为 ECL 或 PECL，电压电源范围为 -3.0 V 至 -3.8 V（或 3.0 V 至 3.8 V）。LVEL14 具有多路复用时钟输入，可用于分发更低速扫描或测试时钟以及高速系统时钟。处于低电平（或保持开路并由输入下拉电阻拉为低电平）时，SEL 引脚将选择差分时钟输入。公共启用 (EN) 同步，因此输出仅在处于低电平状态时才启用/禁用。这样会避免当设备启用/禁用时产生短时钟脉冲，这种情况可能发生在异步控制中。内部触发器在输入时钟的下降边进行计时，因此，所有相关规格限制都参考到时钟输入的负边。仅为此器件提供 VBB 引脚，即内部产生的供应电压。对于单端输入的情况，将未使用的差分输入联接至 VBB，作为开关参考电压。VBB 还可将 AC 耦合输入重偏置。使用时，通过 0.01 5F 电容器对 VBB 和 VCC 进行去耦合，并将源电流或汲电流限制为 0.5 mA。不使用时，VBB 应保持开路。
