| Abstract: | 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. |
