Abstract: After reviewing the development background and the features of VDSL technology, the paper introduces the structure and features of the VDSL modern-on-chip solution, and the design and implementation of a high-speed transmission unit based on this solution, including software and hardware, then gives two typical application examples and the related test data. Using the modular design and smart configuration feature of this high-speed transmission unit combined with simple external interface circuit,the far-distance wired transmission of Ethernet or high-speed syne interface can be implemented. Via single twisted pair, high-speed digital signals can be transmitted over a distance of more than 1km.
