A method and system to enhance accuracy of measurement of distance Z in a TOF system dynamically provides tight control over the phase and/or timing relationship of clock pulses used in the TOF system. Enhanced frequency control is imposed over a high speed oscillator whose output(s) control a timing generator, whose outputs are coupled to circuitry associated with the detection array in the TOF system, and with the TOF clock timing circuitry. The timing generator is coupled to a delay locked loop (DLL) and/or phase lock loop (PLL), which loop(s) are feedback coupled to the waveform circuit that drives the source of electromagnetic energy emitted by the TOF system.
