Phase detecting device and method of detecting phase

A phase detecting device comprising:

• at least one operator configured to correspond to transitions of at least two data sampling a multi-level signal at at least two adjacent sampling timings, and configured to operate a sampling control signal for adjusting the sampling timing at which the multi-level signal is sampled;
• an operator selecting circuit configured to generate an operator selecting signal for selecting at least one of the at least one operator;
• and
• at least one switch configured to transmit driving voltages to the at least one operator from a voltage source based on the operator selecting signal.

A phase detecting method comprising:

• receiving at least two continuous digital data signals from a converter;
• determining phase information based on transition information of the at least two digital data signals;
• selecting an operator configured to receive a phase determining signal based on the transition information;
• outputting the phase determining signal to the selected operator;
• and
• transmitting a switch control signal to a switch connected between the selected operator and a voltage source.
