摘要
本设计采用单片集成的RS - 4 85接口芯片MAX1490B实现了某雷达信号处理系统中 4 85标准信号的物理接入 ,减少了芯片的使用数量。另外 ,根据设计需要巧妙地采用DSPTMS32 0F2 0 6 ,在完成异步数据格式与同步数据格式之间的转换的同时 ,实现了本系统的BIT模块功能。设计精巧紧凑 ,大大地减小了设计规模。
The design adopt MAX1490B, single compositive RS-485 interface chip, to finish a 485 standard signal's real join in the alertness MTD radar signal process system, it reduces the number of the used chip. In addition, according to the need of design, it subtly use DSP TMS320F206 finished conversion between asynchronism data format and synchronization data format and the system BIT function module. The design is refinement and tight, which minished the design's scale by a long way.
