【摘要】 本文简要介绍一种多功能快逻辑信号电平转换电路的设计与实现。该电路主要用于不同逻辑电平的高速逻辑信号之间的适配。基于电路复用结构,可实现NIM、ECL、TTL三种逻辑电平、六种转换方式。在一个单插宽标准NIM插件上,对于每种逻辑电平该电路可提供8个输入通道。NIM、TTL信号输出均采用互补输出方式,ECL信号输入/输出则为差分信号。更多还原

【Abstract】 The design and implementation of a multi-functional levels adaptation circuit for fast logic signals will be described briefly in this paper.This circuit is mainly adopted to accomplish levels adaptation between several fast logic signals.As the circuit is designed based on a multiple-using structure,it can supply 6 types conversion mode between the NIM,TTL,ECL logic level signals.The circuit can supplies 8 input channels for each level in single-width-standard NIM module.TTL and NIM outputs are a pairs of complementary output signals,and ECL input/output are differential signals.更多还原
