One-chip semiconductor integrated circuit device having a digital signal processing circuit and an analog signal processing circuit

摘要

A one-chip semiconductor integrated circuit device includes a digital signal processing circuit (2) which processes a digital signal in synchronism with a first clock signal (CK1), and an analog signal processing circuit (3) which samples an analog input signal in synchronism with a second clock signal (CK2) having a phase different from that of said first clock signal.
