发明名称 DE-EMPHASIS SYSTEM AND METHOD FOR COUPLING DIGITAL SIGNALS THROUGH CAPACITIVELY LOADED LINES
摘要 A system for de-emphasizing digital signals, such as address signals, boosts the level of the signals for one clock period prior to transmitting the signals through signal lines that may have a relatively large capacitance. The system may include a delay circuit that delays the digital signal for a period corresponding to one period of a clock signal. The system may also include a first multiplier circuit that generates a first intermediate signal by multiplying the first and second logic levels of the digital signal by a first multiplier. Similarly, a second multiplier circuit generates a second intermediate signal by multiplying the first and second logic levels of the delayed signal from the delay circuit by a second multiplier. A combining circuit then subtracts the second intermediate signal from the first intermediate signal, and the resulting signal is level-adjusted to generate the de-emphasized signal.
