Abstract
A data transmitter-receiver for reducing high-frequency noise which leads to a cause of performance deterioration of a radio instrument, and for eliminating dissipation current. The data transmitter-receiver transmits transmitting data to a modulator-demodulator connected to a radio instrument, and receives receiving data from the modulator-demodulator. A terminal controlling section 3 of the data transmitter-receiver performs data processing on the receiving data, thus outputting to a data-terminal, and performs data processing transmitting signal from the data-terminal, thus generating the receiving data. The terminal controlling section causes the low-speed clock LC to generate on the clock generating section during transmission-reception-period both of the receiving data and the transmitting data, and causes the high-speed clock HC to generate on the clock generating section during non-transmission-reception-period both of the receiving data and the transmitting data, both the high-speed clock and the low-speed clock are operating-clock. Furthermore, the operating ratio detector causes the low-speed clock to generate when the operating ratio of the terminal controlling section is low.
