Abstract

Shipborne balanced serial communication interface adopts balanced driving and differential receiving circuit, so its anti-interference ability strengthens. However, ground signal connecting is ignored when forming a balanced serial communication link. This paper analyzes its potential risk of common mode voltage interference and radiation EMI. Furthermore, when reasoning grounding of balanced serial communication interface, we give several measures, such as floating ground and isolated interface, to enhance properties of grounding system for shipborne balanced serial communication interface according to engineering experience.
