Abstract: PURPOSE: A circuit and a method for recovering a timing are provided to reduce the number of output ports in a symbol detecting integrated circuit and to reduce the components of ambient logic for simplifying the structure of circuit while reducing producing cost by outputting a phase detecting information as a pulse width modulating signal. CONSTITUTION: An analog signal is converted into a digital signal by sampling in response to a symbol clock, then the digital signal is interpolated, equalized, and phase detected for generating a timing error. Then, a phase detecting signal is loop filtered for deciding a chasing scope and a chasing depth in response to the timing error to generate 10-bit digital data. Therefore, a modulating signal of pulse width is outputted for having a pulse width responding to the 10-bit data value of the loop filtered digital signal. Then, the modulating signal of pulse width is low pass filtered for generating a symbol clock having a frequency varied according to the level of the low pass filtered analog signal. Therefore, the symbol clock is supplied as a sampling clock of an analog-digital converting step. If the sampling speed is faster than the symbol speed inputted from an analog digital converter(10), a timing error is generated. Then, the modulating signal of pulse width is generated in response to the timing error for lowering the voltage level fed to a voltage controlling oscillator(50) to lower the frequency of the symbol clock.
