Abstract: A method for data detection includes signal transition detection of an input signal. When a falling edge is detected, a rising edge in a negative signal is generated. When a rising edge is detected, a rising edge in a positive signal is generated. Data is latched from the bus for the rising edge of the positive/negative edge signal. A falling edge in the positive/negative edge signal is generated after a period of time. The steps are repeated for each detected signal transition. A data detection apparatus includes a QAEDN to generate a rising edge on the negative signal for detected falling edges. A memory unit latches data from the bus for rising edges of the negative signal. A QAEDP generates a rising edge on a positive edge signal in response to detected rising edges. A memory unit latches data from the bus for rising edges of the positive signal.
