摘要： A phase locked loop (PLL) which has a desired frequency characteristic even though a manufacturing process of a semiconductor integrated circuit has fluctuations. The semiconductor integrated circuit includes the PLL and a control unit. The PLL has a phase frequency detector, a loop filter, a voltage controlled oscillator (VCO) and a divider. The VCO comprises a voltage-current converter (VIC) and a ring oscillator. In response to a control voltage, the VIC generates a control current for setting each operating current of the ring oscillator. The control unit switches the PLL to a calibration operating period of its open loop and a normal operating period of its closed loop.

摘要： Disclosed is a semiconductor IC device using a low-price oscillator, which is capable of bidirectional communication with a host and features a low price. In bidirectional communication between a host and a device, the device comprises a synchronization establishment unit, a frequency difference detector, a frequency generator, and an oscillator providing a reference signal. The synchronization establishment unit to which an output signal from the host is inputted outputs a received signal, a synchronization establishment signal and a reception data. The frequency difference detector detects a frequency difference between a received signal and a transmitting signal, and outputs a frequency coordination signal to the frequency generator. The number of frequency division of the frequency generator is controlled by the frequency coordination signal, and the frequency generator is capable of matching the frequency of the transmitting signal which is an output signal with the frequency of the received signal.
