Abstract :
The multi-interface transport card is designed for equipments with different interfaces, which could realize the functions such as twisted pair transmission with LVDS level, optical-fiber transmission with LVPECL level and twisted pair transmission with RS422 level. This design can test the equipment which has the appropriate interface with the appropriate transmission mode. In the twisted pair transmission with LVDS level and optical-fiber transmission with LVPECL level, the design use pre-emphasis driver and receiver equalization to improve the long-distance transmission capacity of LVDS data. In twisted pair transmission with RS422 level, the design takes the 4-channel interface chip in both transmitter port and receiver port, so as to increase the number of transmission port.
