A system and method is described for providing a single pin reset for a mixed signal integrated circuit. The system and method provides for a single reset signal/pin of the integrated circuit to be utilized to generate all internal resets for the analog and digital circuitry/sections of the mixed signal integrated circuit. In one form, a state machine generates a reset signal for a phase locked loop synthesizer that is utilized to generate internal system clocks for the analog and digital circuitry, as well as a digital reset signal that provides reset signals to the various digital sections circuitry of the integrated circuit. Preferably, the chip reset signal is provided for a longer period of time than the PLL reset signal in order to assure that the PLL is running and generating clocking signals before the digital logic is clocked. |
