    • A digital compensation phase locked loop circuit of a semiconductor device includes a phase locked loop circuit including a voltage controlled oscillator having capacitors at oscillation nodes and consecutively controlled by an applied voltage, and a digital compensation circuit which variably controls the capacitors at the oscillation nodes of the voltage controlled oscillator in accordance with an input phase difference. A gain of the conventional voltage controlled oscillator whose gain is determined by an applied voltage is discretely changed by a control signal of the digital compensation circuit. The digital compensation circuit dynamically controls the gain so as to secure the optimum phase margin by applying a load (capacitor) to the oscillation node of the voltage controlled oscillator with respect to a phase lead and decreasing the load (capacitor) with respect to a phase delay.

    • An eye-opening margin measurement method for a high-speed serial data reception circuit which uses a circuit for eye-opening margin measurement involving operation of a clock data recovery circuit without fixing the clock phase. In this method, an error acceleration test can also be made on received data by giving an offset pulse signal to phase information to add a jitter component. The method uses a semiconductor integrated circuit device which includes a serializer/deserializer circuit (SerDes) for receiving serial data and a reference serializer/deserializer circuit (Ref_SerDes) for receiving an accompanying clock signal. The SerDes circuit converts received serial data into parallel data through a recovery clock whose phase is controlled using phase control signal P_CS generated by the Ref_SerDes circuit. An offset pulse signal Offset_Pulse from the pulse-forming circuit is applied to the phase control signal P_CS to make eye-opening margin measurement.
