TDM over IP技术的一个难点在于接收方时钟同步问题
） Abstract： IP-based TDM data transmission (TDM over IP)
By the transparent transmission through IP network of E1 signal, IP technology and the traditional TDM terminal combine together
As taking the low cost advantage of IP network,we can establish seamless connection between IP network and the existing TDM terminal equipment
the receiver clock synchronization is a difficulty problem of TDM over IP technology
TDM signal as a synchronous bit stream, in order to communicate normally, the receiver and the sender must be kept strictly in sync
The design uses Xilinx VII pro FPGA development platform and the VHDL language
The design has completed FPGA output interface adaptive clock recovery have been accomplished using VHDL hardware description language
The experimental results show the effectiveness of the method
