差分接收器允许的高频损失
摘要：
Say you need to communicate one digital signal from box A to box B 15.2m (50 ft) away. You choose a single-ended, 3.3V, 50Ω line driver running on RG-58 coax at 1000 Mbaud (1 nsec/bit), with a rise/fall time of 250 psec.
The response of this system appears in Figure 1. The figure shows the actual eye pattern, as simulation predicts, using solid lines. With a dashed line, it depicts the ideal transmitted waveform, assuming no skin-effect distortion or attenuation. The transmitted data pattern is " ... 1111010001111 ... ."
