Abstract: A pin-configurable frequency synthesizer for providing a choice of physical pin assignments/configurations without costly design and/or bonding changes. A functional block, having a plurality of functional conductors, is provided. The pin-configurable frequency synthesizer is housed in a chip package that includes a plurality of physical pins. A configuration matrix having a plurality of transmission circuits for connecting the functional conductors to the physical pins is also provided. A control circuit for controlling the transmission circuits of the configuration matrix is further provided. This control circuit includes programming logic and a logic array for generating control signals for each of the transmission circuits of the configuration matrix. These control signals direct the transmission circuits to selectively couple each functional conductor to a respective physical pin in accordance with a desired pin assignment.
