摘要
首先回顾了VDSL技术的发展现状和技术特点,然后介绍了一种单芯片VDSL系统解决方案的结构和基于该技术的高速传输单元设计方案,包括系统基本原理,软硬件设计,并给出了系统的2种典型应用示例和有关测试数据。该高速传输单元具有模块化、灵活配置的特点,配合简单的外部接口电路,可实现一路以太网接口或高速同步接口的有线远距离传输功能,利用单对双绞线作为传输介质,传输距离可达1km以上。
After reviewing the development background and the features of VDSL technology, the paper introduces the structure and features of the VDSL modem-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 sync interface can be implemented. Via single twisted pair, high-speed digital signals can be transmitted over a distance of more than lkm.
