摘要：A pin-configurable frequency synthesizer for providing a choice of physical pinassignments/configurations without costly design and/or bonding changes. A functionalblock, having a plurality of functional conductors, is provided. The pin-configurablefrequency synthesizer is housed in a chip package that includes a plurality of physicalpins. A configuration matrix having a plurality of transmission circuits for connecting thefunctional conductors to the physical pins is also provided. A control circuit for
controlling the transmission circuits of the configuration matrix is further provided. Thiscontrol circuit includes programming logic and a logic array for generating controlsignals for each of the transmission circuits of the configuration matrix. These controlsignals direct the transmission circuits to selectively couple each functional conductor toa respective physical pin in accordance with a desired pin assignment. A user uses theprogramming logic to program the logic array in accordance with the desired pinassignment.
