Abstract
Methods, systems, and media to time-share the signal detection between reference voltages for a data transmission are contemplated. Embodiments include a time-sharing detector that is designed to enable comparison of a first reference voltage and a second reference voltage against the serial data transmission in a specified pattern. In many embodiments, the pattern is pre-defined and, in some embodiments, the pattern includes an overlap period. During the overlap period both the first and the second reference voltages are compared with the data transmission to determine if valid data can be detected. Upon detecting a valid bit based upon one of the reference voltages, an output signal is generated to indicate that the data transmission includes a valid data signal. Advantageously, alternating between the comparisons can reduce power consumption. In many embodiments, the power reduction can be, for example, 50%, depending upon the specified pattern.
