基于AD9762和EP2C70的低功耗轻型化调制器设计与实现

Consume according to the low achievement of the AD9762 and the EP2C70 light turn to make a machine of design and realization

本文基于低功耗、轻型化调制器的目的,采用了低功耗、小封装的FPGA和DA芯片,即AD9762和EP2C70联合的设计思想,给出了QPSK调制器的原理和工程实现方法;运用FPGA软件编程的方法实现了数字化的QPSK调制器,并通过AD9762实现数字到模拟信号的转换,取得了调制器低功耗、小型化,达到了设计目的,满足应用需求。

This text consumes according to the low achievement, light turn the purpose of making the machine, adopted a low achievement to consume, small the FPGA and DA chip for packing, namely the design thought of AD9762 and EP2C70 consociation, give QPSK make principle and engineering of machine to carry out a method;Made use of the method of FPGA software plait distance to carry out QPSK that the number turns to make a machine, and carry out number to arrive the conversion that imitates signal through an AD9762, obtained to make a machine low achievement consume, small scaled turn, come to a to design a purpose, satisfy an applied need.
