【应用笔记】在Stratix Ii器件中使用校正的片上串行终端(Using Calibrated On-Chip Series Termination in Stratix II Devices) 片上串行终端(Rs OCT)由于最佳的的阻抗匹配，提升了信号完整性和I/O性能。片上串行终端消除了外部串行电阻的需要，简化了PCB设计。 On-chip series termination (RS OCT) improves signal integrity and I/O performance due to optimized impedance matching. On-chip series termination eliminates the need for external series termination resistors and simplifies the design of a printed circuit board (PCB). Using Calibrated On-Chip Series Termination in Stratix II Devices April 2005, ver. 1.0 Application Note 384 Introduction On-chip series termination (RS OCT) improves signal integrity and I/O performance due to optimized impedance matching. On-chip series termination eliminates the need for external series termination resistors and simplifies the design of a printed circuit board (PCB). RS OCT is implemented through output driver im……
