摘　　要：声光可调滤波器(AOTF)是未来全光网络中实现波长路由选择的首选器件,为制作该器件必须首先完成驱动模块射频电路的设计。文章介绍了一种声光可调谐滤波器驱动系统的实现,该系统基于ARM7控制的用于中心波长为1500的波分复用光网络;基于频率合成芯片ADF4360-8以及ATMEL公司的AMR7芯片AT91SAM7S256。利用仿真软件ADIsimPLL配合设计芯片外围电路。以这种方式设计的射频电路覆盖了1500～1600nm的光谱范围,能实现1nm的波长调谐,具有结构简单、操作方便、稳定性高等特点。The acousto-optic tunable filter （AOTF） is the main device to provide wavelength routing in all-optical network. The manufacture of AOTF requires high quality RF control circuit. This paper introduces a way to realize the RF circuit suitable for 1550 nm WDM optical network based on the control of ARM7. It is based on frequency synthesize chip ADF4360-8 and embedded chip AT91SAM7S256 of Atmel Corporation and makes use of the simulation tool ADIsimPLL to design the circuit. Our design described in this paper is possible to cover the range 1500-1600 nm. The resolution can be set to 100 kHz. It is compact, easy controllable, and with good stability.
