Electronic device for filtering crosstalk using adaptive filter and operating method thereof

An operating method of an electronic device, the operating method comprising:

• receiving a first signal via a first signal line, receiving a third signal via a third signal line located between the first signal line and a second signal line, and receiving a second signal via the second signal line;
• outputting a first final signal corresponding to the first signal;
• adjusting a pole frequency and a gain coefficient based on the second signal and the first final signal, to obtain an adjusted pole frequency and an adjusted gain coefficient;
• outputting a first compensation signal by applying (i) filtering based on the adjusted pole frequency and (ii) gain based on the adjusted gain coefficient, to the second signal;
• and
• filtering crosstalk included in a signal received through the first signal line based on the first compensation signal,
• wherein the first signal line and the third signal line are directly adjacent, the third signal line and the second signal line are directly adjacent, the first signal is a data signal including data information, and the second signal and the third signal are clock signals having a correlation with one another.

An electronic device comprising:

• a plurality of signal lines that are consecutive to each other;
• a plurality of crosstalk filters configured to compensate for crosstalk between the plurality of signal lines by applying filtering based on a pole frequency and gain based on a gain coefficient to signals received over the plurality of signal lines;
• and
• an adaptive filter configured to adjust the pole frequency and the gain coefficient of each of the plurality of crosstalk filters, wherein the plurality of signal lines comprise:
• a first signal line configured to transfer a data signal including data information;
• a second signal line located between the first signal line and a third signal line and configured to transfer a first clock signal;
• and
• the third signal line, wherein the third signal line is configured to transfer a second clock signal that is opposite in phase to the first clock signal,
• wherein the adaptive filter is connected to the third signal line, and
• wherein the adaptive filter is configured to adjust the pole frequency based on a final signal generated by filtering crosstalk from the second clock signal and the data signal, and to adjust the gain coefficient based on (i) an adjustment signal to which filtering based on the adjusted pole frequency is applied and (ii) the final signal.
