摘要
提出了一种用于多点数据传输的BLVDS(Bus low voltage differential signal)驱动器电路设计。设计中将电压模式驱动器电路和双电流源模式驱动器电路相结合实现多点数据传输,既充分利用了LVDS技术高速、低功耗和低噪声的优点,又解决了传统的LVDS驱动器电路只能用于点对点应用,不能用于总线数据传输的问题。仿真结果表明,该BLVDS驱动器电路的传输速率可达100Mbps,电气性能指标符合TIA/EIA-899协议标准的要求。
The design of BLVDS(Bus low voltage differential signal) driver for multipoint data transmission was presented.The circuit combined the voltage-mode driver circuit and the dual-current-mode driver circuit together.It not only take the advantage of LVDS technology e.g.high speed,low power consumption and low noise advantages,but also solve the problem that the LVDS driver circuit can only be used for point-to-point applications.Simulation results show that the circuit can operate at a high speed of 100Mb/s,its power dissipation is about 33mW.At the same time,its electrical characteristics is also accorded with the requirements of TIA/EIA-899.
