Abstract
A driver may include a plurality of data output units and/or a multi-phase clock generator. The plurality of data output units may be configured to output data based on a plurality of clock signals. The multi-phase clock generator may be configured to receive a master clock signal to generate the plurality of clock signals having different phases in a period of the master clock signal and/or to provide the clock signals to the data output units. A number of the clock signals may correspond to a number of the data output units.
Claims9
A driver comprising:
- a plurality of data output units configured to output data based on a plurality of clock signals, respectively;
- and
- a multi-phase clock generator configured to,
- receive a master clock signal to generate the plurality of clock signals with identifiers, the plurality of clock signals having a same frequency as the master clock signal and different phases in a period of the master clock signal and configured to provide the plurality of clock signals to the respective data output units, the identifiers identifying the plurality of data output units, and
- provide a second clock signal of the plurality of clock signals to an (i+j)th data output unit if a first clock signal of the plurality of clock signals is provided to an (i)th data output unit, i being a natural number, and j representing a delta value and being a natural number greater than one,
- wherein a number of the plurality of clock signals corresponds to a number of the plurality of data output units, and
- the plurality of clock signals including the first clock signal and the second clock signal are immediately adjacent sequentially generated.

A method comprising:
- receiving a master clock signal;
- generating a plurality of clocks having a same frequency as the master clock signal and different phases in a period of the master clock signal;
- providing the plurality of clocks to a respective plurality of data output units as a plurality of clock signals with identifiers, a number of the plurality of clock signals corresponding to a number of the plurality of data output units the identifiers identifying the plurality of data output units, the providing including providing a second clock signal of the plurality of clock signals to an (i+j)th data output unit if a first clock signal of the plurality of clock signals is provided to an (i)th data output unit, i being a natural number, and i representing a delta value and being a natural number greater than one;
- and
- outputting data from the plurality of data output units based on the respective plurality of clock signals, wherein the plurality of clock signals including the first clock signal and the second clock signal are immediately adjacent sequentially generated.
