Abstract
A simultaneous bi-directional data transferring method includes obtaining a combined signal from a portion of a data line proximate a host device. The combined signal is a signal that combines input and output signals that are being transmitted over the data line. The output signal is a signal transmitted by the host device, and the input signal is a signal transmitted by a remote device. The combined signal is provided to first and second receivers of the host device. A first fixed reference voltage is inputted to the first receiver, and a second fixed reference voltage is inputted to the second receiver. The first and second fixed reference voltages are independent of values of the output signal. A first output receiver signal is outputted from the first receiver using the first fixed reference voltage and the combined signal, and a second output signal is outputted from the second receiver using the second fixed reference voltage and the combined signal. The input signal is reproduced using the first and second output receiver signals. A length of the data line is set to enable the input signal transmitted by the remote device to arrive at an input point of the host device at an integer multiple of a clock cycle.
