A phase-locked loop (PLL) circuit includes an input for receiving a timing reference signal, a phase detector circuit coupled to receive the timing reference signal, a controllable oscillator circuit controlled according to an output of the phase detector circuit, and a feedback divider circuit having an output coupled to the phase detector and an input coupled to the controllable oscillator circuit. The phase-locked loop circuit is coupled to output one of a plurality of output signals having an arbitrary frequency relationship to each other according to a frequency selection mechanism, the frequency selection mechanism including one or more input terminals coupled to control a divide ratio of the feedback divider circuit. The frequency selection mechanism selects one of a plurality of stored values. The selected stored value controls, at least in part, a divide ratio of the feedback divider circuit, thereby providing a pin programmable device capable of selecting among output frequencies having an arbitrary relationship to each other.
