【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 (R_S 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).an384.pdf
