摘要:
 为了满足飞控系统对总线传输速度和传输距离的要求，文中提出了一种适用于长距离传输的高速自适应均衡1394b收发器电路结构。该收发器发送端采用了输出幅度、共模电平可调的驱动器电路，通过增加输出电压的幅度可以适应更长的传输距离；接收端采用了自适应的连续时间线性均衡电路，通过负反馈分别针对信道的高频特性和低频特性进行不同幅度的增益补偿，解决了由于信道与频率相关的衰减特性带来的码间干扰的影响，提高了接收电路的误码性能。该收发器电路采用0.13μm CMOS工艺设计，仿真结果表明，在1394b协议规定的S800模式下，采用UTP CAT5e线缆时，该电路最高可以支持50 m的传输距离。
Abstract:
 In order to meet the transmission speed and distance requirements of the flight control system,propose a high speed adaptive e-qualization structure for long distance transmission of 1394b transceiver chip. The transmitter of the chip takes a driver with adjustable output common and difference voltage which can achieve long transmit distance by increasing output voltage. The receiver uses a continu-ous time adaptive linear equalization circuit to compensate the different loss character of high frequency and low frequency by negative feedback,solves the ISI problem and improves the bit error performance of the receiving circuit. The chip uses 0. 13μm CMOS technolo-gy. Simulation result shows that the chip can support 50 m using UTP CAT5-e cable at S800 mode of 1394b protocol.
