| Abstract: | In the bit stream transport board of digital television, digital television bit streams are transported to the STB as low voltage differential signaling (LVDS) signals in order to solve the data transmission between high-rate and low-voltage, and data transmission with high rate is implemented with no certain supplied voltage. In this paper, the voltage transformation from TTL to LVDS is implemented based on the chip of DS90c031, and the project is feasible. The outputting bit-rate is from 3 Mb/s to 30 Mb/s, and the bit streams are continuous and have no failure bits. |
