摘　　要：提出了一种SDH帧定位芯片的设计方案,能够定位符合ITU-T G.707标准STM-1、STM-4、STM-16与STM-64帧、调节字节中的比特位、并行64位解扰码、数据转换、LOF告警检测和OOF告警检测功能。通过编写RTL代码与仿真,FPGA硬件平台验证、与相关SDH测试仪器对接验证,已广泛应用于SDH检测仪表和SDH设备等SDH相关产品研发。A chip design scheme for SDH frame alignment is presented. According ITU-T G.707, it can align the frame of STM-1,STM-4,STM-16,STM-64,adjusting the location of bit in byte, descrambling on parallel 64 bits, transferring data, detecting LOF alarm and OOF alarm. The RTL has been coded in verilog and simulated with sottware, certificated by FPGA hardware platform .It has been widely used in research and development of SDH measurement instrument and equipment and so on.
