基于FPGA的小功率立体声发射机的设计

介绍了基于FPGA,利用数字频率合成技术实现的小功率立体声FM调频发射机的设计.采用FPGA完成对核心芯片MC145152的控制,可自动改变并测量发射频率并用液晶显示;同时实现了频率扩展、自制音源、立体声编码等功能,使该方案更加完善、实用.本设计基于超高速硬件描述语言VHDL在Xilinx公司的SpartanⅡ系列的XC2S2005PQ-208芯片上编程实现,经测试,整机功能齐全,性能指标优良.

The Design of Low Power Stereo FM Transmitter Based on FPGA

This paper introduces the design of the low power stereo FM transmitter based on FPGA,realized by the digital PLL principle. The core chip MC145152 is controlled by FPGA. It can automatically change and measure the frequency and display it by LCD. In the meantime it realizes the functions of expanding the frequency, designing the homemade sound barrier, stereo coding etc, which make the design better and more practical. The design is programmed with VHDL and realized in the chip of XC2005PQ-208 Xilinx series. It is proved to be well functioning, and the capability index is good after testing.
