摘要
介绍了高速调制解调芯片CMX869的主要特性及工作时序。利用低压单片机W78LE54从硬件结构和软件设计两方面阐述了低功耗Modem的设计方案,给出了系统的硬件结构及软件流程图。同时对影响功耗的主要因素进行了分析,提出了进一步降低系统功耗的方法。该方案结构简单,能够满足远距离通信需要。
A high-speed Modem chip CMX869 was introduced, based on the brief analysis of its main characteristics and time sequence. Combining the low-voltage mcu W78LE54 from Winbond, low cost, and power modem was demonstrated in detail from the hardware and the software designs, including the hardware diagram and the program flow chart. The design is simple in structure and definitely meets the needs of long distance transmission.
