    摘要: The invention relates to packet switched networks, and more particularly to a circuit and a method for clock recovery in cell-relay networks, particularly ATM (Asynchronous Transfer Mode) networks offering constant bit rate services. The multimode clock recovery circuit has an embedded digital phase locked loop including an input circuit capable of generating a phase signal from at least two types of input signal. The phase signal controlling the output of the phase locked loop generates clock signals for the constant bit rate services.
