1. A method for generating a reference signal, performed in a timing controller of a display apparatus, the method comprising:
generating a reference signal having a training pattern being repeated with a periodicity of two clock terms (CTs); and
transmitting the reference signal to a phase locked loop (PLL),
wherein each CT has an embedded clock bit (CB) and a plurality of data bits, and
wherein, in a single period, the reference signal has a rising edge at a start point of a first CB corresponding to a first unit interval (UI) of a first CT, and a rising edge at an end point of a second CB corresponding to a first UI of a second CT,
in a high state included in the first CT is different from a number of Uls in a high state included in the second CT,
wherein a number of Uls in a low state included in the first CT is different from a number of Uls in a low state included in the second CT, and
wherein a signal level of the first UI of the first CT is different from a signal level of the first UI of the second CT.
