The present invention relates to a false lock prevention circuit and method which is used to cause a delayed locked loop (DLL) to escape from false lock such as harmonic lock or stuck lock, when the false lock occurred in the DLL, and a DLL using the same. The false lock prevention circuit includes a harmonic lock detector configured to detect harmonic lock and a stuck lock detector configured to detect stuck lock. The harmonic lock detector includes a plurality of flip-flops configured to sample a plurality of delayed clocks and a logic unit. The harmonic lock detector compares a reference clock signal with the plurality of delayed clock signals, and detects whether or not the positive edges deviate from one cycle of the reference clock signal.

Differential current driving type transmitter and receiver, and an interface system having the transmitter and receiver. The transmitter includes a current source, a current direction selecting block, and a balancing switch block. The current source sources currents to a pair of transmission lines or sinks currents flowing through the pair of transmission lines. The current direction selecting block transfers a current flowing from the current source to one transmission line of the pair of transmission lines and a current flowing through the other transmission line of the pair of transmission lines to the current source. The balancing switch block initializes the pair of transmission lines to a balanced state.
