ABSTRACT:
A low power and low voltage frequency synthesizer includes a memory containing information to provide divisor information to the variable divider of a phase locked loop and information to select predetermined values of capacitance to connect to the frequency determining resonant network of the VCO to provide a coarse tuning. This tuning is then further modified by the normal operation of the phase locked loop.
