Abstract:
An analog-based architecture is used to produce tap spacings in an n-tap UI-spaced equalizer without the need for digital clock-driven elements. The analog voltage-controlled delay cell circuits control the amount of applied delay based on the measured phase difference between quarter-rate clock signals. Because low speed clock signals are sufficient for comparison purposes, the analog delay cells can be placed before the quarter-rate multiplexors in the data path. The use of analog-based delay cells eliminates the need to route high-speed clock signals to multiple digital delay elements that are typically used to achieve UI-spaced data signals in n-tap FIR equalizers. Timing margin issues can also be eliminated since digital clocked elements are not used to produce the UI spaced delays. The analog-based delay approach also consumes less power relative equalizers that use multiple digital delay elements requiring high speed clock signals.

Claim (Index 19):
The n-tap finite impulse response transmit equalizer of  claim 17 , wherein the clock signal and the 90\u00b0 phase-shifted version of the clock signal are generated by a quarter-rate clock of an integrated circuit, a very large scale integration system, or a system-on-chip.
