ABSTRACT:
A monolithic oscillator having dual programmable fixed frequency outputs includes crystal-less oscillator circuitry utilizing frequency-locked feedback to generate ai signal having a select frequency, the frequency being stabilized over temperature and voltage by compensation circuitry associated with the crystal-less oscillator circuitry. A programmable prescaler is coupled to the crystal-less oscillator circuitry for varying the frequency of the signal generated by the crystal-less oscillator circuitry by a select amount. The monolithic oscillator further includes inputs for receiving an external signal, such as an external reference signal, or for connection to a crystal for providing an alternative frequency reference. A multiplexer is used to select either the external signal (or crystal) or the signal from the crystal-less oscillator circuitry to be used for the output signal. Monolithic oscillator further includes a programmable frequency divider coupled to the multiplexer to vary the frequency of the signal from the multiplexer by a select amount to one of the dual outputs. The other output being used as a reference output.
