概览

MCH12140 或 K12140 是一款相位频率检测器，用于在锁定时需要最低相位和频率差异的锁相环应用。配合使用 MC100EL1648 等高性能 VCO 时，可以实现高带宽 PLL。该器件的功能与 MC12040 相位频率检测器兼容，但最高频率扩展到了 800 MHz。 参考 (R) 和 VCO (V) 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。参见 AND8040 了解更多信息。该器件采用小型表面贴装 8 引线 SOIC 封装。该器件有两个版本，可提供对于两个现有 ECL 标准的 I/O 兼容性。MCH12140 可兼容 MECL 10H 逻辑电平，而 MCK12140 可兼容 100 K ECL 逻辑电平。此器件还可用于 +5.0 V 系统。参见 AND8020 了解端接信息。

  • 800 MHz Typical Bandwidth
  • Small Outline 8-Lead SOIC Package
  • 75 kΩ Internal Input Pulldown Resistors
  • > 1000 V ESD Protection
  • Pb-Free Packages are Available

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
