Data receiver, display device including the same, and method of receiving data

A display device comprising:

• a timing controller which communicates with a host through a mobile industry processor interface (MIPI) and generate image data;
• and
• a display panel which displays an image corresponding to the image data,
• wherein the timing controller includes:
• a first reception unit which receives first data through a first lane,
• a second reception unit which receives second data through a second lane,
• a remapper which rearranges the first data and the second data to generate the image data, and
• a detector which compares the first data and the second data to detect a skew between the first lane and the second lane,
• wherein the first reception unit includes a first clock data recovery unit which recovers a first clock and first payload data from the first data,
• wherein the first reception unit controls a loop speed of the first clock data recovery unit based on a skew level of the skew, and
• wherein the loop speed is defined as a change rate of at least one of a frequency and a phase of the first clock in a process of recovering the first clock, and
• wherein the first clock data recovery unit includes:
• an oscillator which outputs a clock having a frequency according to a control signal thereto, wherein the clock corresponds to the first clock;
• a phase detector which compares the first data and the clock;
• and
• a control circuit which adjusts the control signal based on an output of the phase detector.

A method of receiving data performed by a timing controller configured to communicate with a host through a plurality of lanes, the method comprising:

• receiving, by a first reception unit, first data through a first lane;
• receiving, by a second reception unit, second data through a second lane;
• detecting a skew between the first lane and the second lane by comparing the first data and the second data;
• recovering, by the first reception unit, a first clock and first payload data from the first data using a first clock data recovery unit by:
• outputting a clock having a frequency according to a control signal using an oscillator;
• comparing the first data and the clock using a phase detector;
• and
• adjusting the control signal based on an output of the phase detector and the skew level;
• and
• recovering, by the second reception unit, a second clock and second payload data from the second data using a second clock data recovery unit,
• wherein the detecting of the skew includes controlling a loop speed of the first clock data recovery unit based on a skew level of the skew, and
• wherein the loop speed is defined as a change rate of at least one of a frequency and a phase of the first clock or second clock in a process of recovering the first clock or the second clock.
