ABSTRACT:
In the context of high-speed serial links, data-dependent jitter compensation techniques performed using phase pre-distortion. Broadly contemplated is an expansion of the notion of pre-emphasis beyond conventional amplitude compensation of ISI, whereby phase pre-emphasis for compensating data-dependent jitter (DDJ) is introduced. DDJ can be addressed by exploiting the relationship between the data sequence and the timing deviation. Phase pre-emphasis improves the signal integrity with little additional power consumption in the transmitter and with no cross-talk penalty.
