采用数字控制输入阻抗:信号完整性与功耗的考虑的对比

On-die termination (ODT) promises higher signaling rates for printed circuit board (PCB) inter-chip interfaces through improved signal integrity. However, when using ODT, there is sometimes an associated power penalty. This application note explains the reason for the power penalty and suggests a simulation technique for comparing the signal integrity and power dissipation of internally and externally terminated versions of an interface.
