Abstract:
A semiconductor device comprises synthesized frequency generation logic arranged to receive a reference signal, and to generate a synthesized frequency signal from the reference signal. The synthesized frequency generation logic comprises programmable divider logic arranged to receive the reference signal and to generate a divided signal comprising a frequency with a period substantially equal to N times that of the reference signal, where N comprises a programmable integer value. The synthesizer frequency generation logic is arranged to generate the synthesized frequency signal comprising a frequency with a period substantially equal to 1/M that of the divided signal, where M comprises a further programmable integer value.
