The slave DLL includes a shifter(136), a manipulation unit(138), and a variable delay circuit(132). The shifter shifts the first digital value to form a second digital value. The manipulation unit adds or subtracts an offset value varying according to PVT(Process Voltage Temperature) conditions to and from the second digital value, and outputs a third digital value. The variable delay circuit delays the second input clock by the time corresponding to the third digital value, and outputs the delayed result.
