An embodiment of the present invention is a technique for timing recovery. A frequency acquisition loop locks a voltage controlled oscillator (VCO) clock of a multi-band VCO to a reference clock. The frequency acquisition loop generates first and second feedback clocks from the VCO clock. A data lock phase loop generates a driving signal corresponding to a phase error signal from interleaved partial response signal (PRS) samples based on the second feedback clock. The driving signal controls the multi-band VCO in a data phase lock mode. A lock detect controller detects a frequency lock condition in a frequency lock mode and a data lock condition in the data phase lock mode based on the first feedback clock and the reference clock.
