摘要
介绍了扩频芯片ＳＴＥＬ２０００Ａ的主要性能，并以ＳＴＥＬ２０００Ａ为核心设计了扩频通信产品的扩频模块，给出了单片机８０５１ 与ＳＴＥＬ２０００Ａ，ＥＰＲＯＭ，ＲＡＭ，ＰＬＬ３００４５ 的接口电路，实验证明这些外围电路简单可靠，在产品设计中得到了实际应用。
The features of STEL 2000A are introduced in this paper. A spread spectrum module is designed by the using of STEL 2000A and its interfaces of STEL 2000A,EPROM,SRAM,ADC,DAC and PLL300 45 devices with 8051 are discussed respectively. These circuits are proved to be simple and reliable in experiments, and are practically used in the product.
