Abstract: An interface circuit for interfacing between an integrated circuit (IC) on a transmitting side and an IC on a receiving side over a line on a printed circuit board comprises an output circuit implemented in the IC on the transmitting side and composed of a current source for supplying a given current and a switching circuit for cutting off the given current according to a binary signal and delivering the given current as a current signal to the line, and an input circuit implemented in the IC on the receiving side and composed of a transimpedance circuit whose input impedance is equal to the one of the line and which converts the current signal into a voltage signal, and a comparator for identifying the voltage signal relative to a given threshold voltage and reproducing the binary signal. This circuitry makes it possible to provide an interface circuit that can be implemented in a CMOS IC during CMOS processing and operated at a low voltage. A threshold voltage for use in identifying a signal on the receiving side is stabilized, thus realizing an interface circuit unsusceptible to influence of a change in CMOS processing or the like.

Abstract: Using a switching signal from a coarse/fine switching and operation mode switching circuit, the width of change of a counter control value during power up is increased, and the width of change is reduced once a steady state is reached. In the steady state, the frequency of updating is limited by a control signal from an update permit control circuit. In the steady state, the frequency band of a current source in an LD driving circuit is reduced in width.
