Abstract: A successful design which used FPGA to do Positive/Zero/Negative Justification for
adapting E1 (2.048Mbit/s) to SDH C-12 is presented. Gray code is adopted to realize the sampling
of write pointer in reading clock domain and induct frequency doubling technology to
deduct/insert reading clock, and a positioning counting device is set to complete the positioning
insert of specified bytes. Asynchronous FIFO and Ping-Pong operation technique are both
adopted. The design realizes stimulation, placement and routing under Quartus II 9.0
circumstances. It is a reusable hardware module which increases performance when compared to
existing solutions. © (2013) Trans Tech Publications, Switzerland.
