本文讨论的“时钟分频逻辑归纳法”是一种时序逻辑设计法,它利用稳定度很高的时钟脉冲,通过分频和逻辑归纳,产生周期及脉宽和时钟周期成整数倍关系的脉冲。以彩色电视同步机的设计作为例子,运用“时钟分频逻辑归纳法”设计成一种新的彩色电视同步机,它比现有同步机少了一块晶体,省去了锁相环路,而且有定时精确性高、性能稳定的特点。 This article discusses the “clock divider logic inductive method” is a kind of sequential logic design method, which uses a high degree of stability of the clock pulse, through the frequency and logic induction, the cycle and pulse width and the clock cycle to produce an integer multiple of the relationship between the pulse . Taking the design of color TV synchronous machine as an example, this paper designs a new color TV synchronous machine by using the “Clock Frequency Division Logic Induction Method”. It has one less crystal than the existing synchronous machine and eliminates the need of phase-locked loop Timing accuracy, stable performance characteristics.
