| Zusammenfassung: | When recovering a clock signal embedded in an interface signal in generation of a used mask signal, a clock recovery device and source driver according to an embodiment of the present invention may generate a mask signal according to the falling edge of a data signal, not a mask rising signal, when the mask rising signal for generating the mask signal is positioned in a data signal section and a data signal represents a high level. The clock recovery device comprises: a clock extraction unit; a time-delay control unit; and a mask signal generation unit.
본 실시예는 인터페이스신호에 임베디드된 클럭신호를 복원할 때, 사용되는 마스크신호를 생성함에 있어서, 마스크신호를 생성하기 위한 마스크라이징신호가 데이터신호구간에 위치하고 데이터신호가 하이레벨을 나타내는 경우, 마스크라이징신호가 아닌 데이터신호의 폴링에지에 따라 마스크신호를 생성할 수 있다. |
