EPLD器件发展现状及其在便携式OTDR中的应用

The Current Development of EPLD and Application in OTDR

本文论述了EPLD器件的发展现状及EPLD的CAD开发工具.对我所开发的便携式光时域反射计(OTDR)中的24位全加器电路及译码电路完成了用GAL系列器件来替代传统的TTL器件,从而把原仪器中的4块并行加法板合并为2块,减小了仪器体积,缩短了生产周期,提高了产品的可靠性.试验测试结果很好,该仪器已正式投入批量生产.

This paper introduces the current development of EPLD and application. Completing the new circuit design by using GAL device to replace the TTL ICs in OTDR. The Experiment results are excellent and avilable to practical applications.
