CC110L 是一款成本优化型低于 1GHz 的射频收发器,适用于 300-348MHz、387-464MHz 和 779-928MHz 频段。电路基于热门的 CC1101 射频收发器,射频性能特性与之完全相同。将两个 CC110L 收发器配合使用可实现低成本双向射频链路。
射频收发器集成了高度可配置的基带调制解调器。调制解调器支持各种调制格式,具有高达 600kbps 的可配置数据速率。
CC110L 针对数据包处理、数据缓冲和脉冲传输提供广泛的硬件支持。
可以通过串行外设接口 (SPI) 对 CC110L 的主要操作参数和 64 位接收和发送 FIFO 进行控制。在典型系统中,CC110L 将与微控制器以及一些其他无源组件配合使用。
