  • 而此顆IC為可程式化的,寫入的方式是藉由I2C通訊協定,由於這顆IC有許多的功能,包括Preamble,Randomizer,Reed-Solomom Encoder及FIR Digital Filter,其載波的頻段可調,data rate的速度可調等等,所以想要AD9853發射出什麼信號,就需要用I2C的方式來寫入。
    為實現I2C通訊協定,本文採用了兩種方式,1. PIC(單晶片)來實現
    2.電腦並列阜加上74系列的控制IC來實現。單晶片的傳輸速度較快,而電腦並列阜的傳輸速度則較慢。



    We use a chip is analog device AD9853,for this purpose,It''s Function include : Preamble , Reed-Solomom Encoder,Randomizer,16 QAM Modulation and FIR Digital Filter。We setup it according to its and program it by I2C communication algorithm which uses PIC(peripheral interface controller) and parallel port to implement 。
