Abstract
In a frequency detection method for adjusting a clock signal frequency to the data rate of a received data signal, the clock signal which is predivided by a factor of 4. The predivided clock signal and the received data signal are each frequency-divided by the same division factor. The frequencies of the two frequency-divided signals are then determined by counting processes and are compared by a subtractor. The frequency difference that is determined is then converted into an analog output signal for controlling the clock signal frequency. This method can be applied in the transmission of data.
