Abstract
An integrated circuit comprises a variable frequency divider for setting a signal transmitting frequency in accordance with a frequency dividing ratio based on externally-provided data. A data converter converts the externally-provided data to a signal for transmission, and a switch selectively provides the externally-provided data to the variable frequency divider and the data converter. As a result, the number of terminals may be reduced, the IC package may be made more compact, the mounting surface area may be reduced, the equipment may be made smaller, and the interference of the data signal provided to the circuit for setting the frequency dividing ratio or the circuit for transmitting data is reduced.
