The disclosed invention is a technology for producing a recovered clock signal using a multi-mode clock data recovery (CDR) circuit that accommodates a flexible range operating frequencies F and consecutive identical digit requirements CID. In a first mode of operation, a controlled oscillator produces the recovered clock signal, and in a second mode of operation, a phase interpolator produces the recovered clock signal. The multi-mode CDR circuit operates in the first mode if (CID/F) is less than a threshold time value and in the second mode if (CID/F) is greater than the threshold time value.
