Reception apparatus with clock failure recovery and transmission system including the same

A communication method between a reception apparatus and a transmission apparatus, the method comprising:

• determining an operation mode of a clock lane based on a clock signal transmitted through the clock lane, and performing an operation based on the determined operation mode of the clock lane;
• determining an operation mode of the data lane based on a data signal transmitted from the transmission apparatus, and performing an operation based on the determined operation mode of the data lane;
• setting the operation mode of the clock lane to a high-speed mode based on an interrupt signal generated when the operation mode of the data lane is switched from a low-power mode to the high-speed mode regardless of the operation mode of the clock lane;
• generating a high-speed internal clock signal corresponding to the high-speed mode when the clock lane operates in the high-speed mode;
• and
• processing the data signal by being synchronized to the high-speed internal clock signal and generating the processed data signal.

A transmission system, comprising:

• a transmission apparatus;
• a reception apparatus;
• and
• a clock lane and at least one data lane connected between the transmission apparatus and the reception apparatus,
• wherein the clock lane and the at least one data lane are configured to operate based on any one mode of a low-power mode and a high-speed mode, respectively,
• wherein the reception apparatus comprises:
• a clock lane control circuit configured to determine an operation mode of the clock lane based on a clock signal transmitted through the clock lane, and perform an operation based on the determined operation mode of the clock lane;
• and
• a data lane control circuit configured to:
• determine the operation mode of the at least one data lane based on a data signal transmitted from the transmission apparatus,
• output a state signal indicating the operation mode of the data lane, and
• perform an operation based on the determined operation mode of the at least one data lane, and
• wherein the clock lane control circuit is further configured to:
• determine whether the operation mode of the data lane has been switched from the low-power mode to the high-speed mode based on the state signal, and
• set the operation mode of the clock lane to the high-speed mode based on a result of the determining regardless of the operation of the mode of the clock lane.

A transmission system comprising:

• an interface comprising:
• a transmission apparatus;
• and
• a reception apparatus;
• and
• a clock lane and one or more data lanes configured to operate in one of a first mode and a second mode;
• wherein the reception apparatus comprises a clock lane control circuit comprising a noise sensing circuit configured to detect external noise occurring on the clock lane, and
• wherein the clock lane control circuit is configured to:
• determine whether an operation mode of the one or more data lanes has been switched from the first mode to the second mode, when the external noise is detected by the noise sensing circuit, and
• set the operation mode of the clock lane to the second mode when the operation mode of the one or more data lanes is switched from the first mode to the second mode regardless of the operation mode of the clock lane.
