It is stated with low energy consumption, a high frequency receiver system that is configured for receiving and forming of transmitted digital data signals to a digital data stream for processing by a microprocessor. The receiver system comprises an integrated circuit with a data slicer, which is formed for accepting the received digital data signals, converting the signals to a digital data stream and passing the digital data stream to the microprocessor. The integrated circuit further includes a peak detector if there are no digital data signals for detecting an ambient circuit noise, developing a voltage reference signal which represents the peak of the ambient circuit noise, and passing of the voltage reference signal is formed on the data slicer. The receiver system further comprises an auxiliary circuit between the peak detector and the data slicer, which has a voltage divider and a charge capacitor is formed for accepting the voltage reference signal and generating a clamp reference for the data slicer to prevent the Data- slicer reacts to ambient circuit noise and passes false digital data streams to the microprocessor.
