Patent ID: 8189727

Claim:
A differential transmitter, comprising: a phase-detecting unit, for detecting a phase relation between a clock signal and a data signal to output a detection result; a switching unit, coupled to the phase-detecting unit, for determining whether to switch the clock signal and the data signal to a first output terminal set of the switching unit, or to switch the clock signal and the data signal to a second output terminal set of the switching unit according to the detection result; a rising edge strobe unit, coupled to the first output terminal set of the switching unit, for latching the data signal at a rising edge of the clock signal, and converting a latching result to a first differential output signal; and a falling edge strobe unit, coupled to the second output terminal set of the switching unit for latching the data signal at a falling edge of the clock signal, and converting a latching result to a second differential output signal, wherein, the phase-detecting unit generating a plurality of phase signals by delaying the clock signal, the phase-detecting unit also generating a plurality of strobe data by latching the data signal directly according to the phase signals respectively.
