| Abstract: | The quartic group signal generator in this paper is based on ITU-T recommendation. G.755. It can output two types s of data cedes, CMI code and BIN code. The data rate reaches 139. 264 Mb/s. A synchro pulse of 139. 264 MHz is also produced. High-speed ECL, EPLD and 8951 are employed in the design. The signal generates several sets of codes, which are programmable and conform with the recommendation G. 755. |
