Originální abstrakt

A transmitter pre-emphasis techniques to overcome high-slope losses of printed circuit board (PCB) with higher-order transfer function used in high-speed serial link design is presented. The pre-emphasis technique based on pulse-width modulation (PWM) using timing resolution instead of amplitude resolution to adjust the filter transfer function is analyzed and applied to channel with high-order transfer function. Leading-edge digital silicon manufacturing processes are pushing the maximum swing below 1.0 V and just PWM scheme is a good alternative for these cases. In addition only one coefficient can be used to set equalizer transfer function in depending on channel properties. Standard approaches to transmitter pre-emphasis and novel PWM pre-emphasis are compared in advanced PCB backplane model.
