概览

MC100EP140 是一款三态相位频率检测器，用于在锁定时需要最低相位和频率差的相锁定环路应用。由于该零部件采用全差分门极设计，因此降低了整个电路的噪声，特别是在高速时。相位/频率检测器（PFD）的基本操作是将输入信号（反馈）与设置的参考信号进行“比较”。参考 (R) 和反馈 (FB) 输入的频率和/或相位不同时，差分 UP (U) 和 DOWN (D) 输出将提供脉冲流，如果减去和集成这些脉冲流则会提供用于控制 VCO 的误差电压。该器件采用小型表面贴装 8 引线 SOIC 封装。EP140 的输出为 400 mV，可实现更快的切换时间和更大的带宽。此器件还可用于 +3.3 V 系统。为了正确操作，R 和 FB 输入的输入边沿速率应小于 5 ns。有关相锁定环路操作和应用的更多信息，请参见 AND8040。
