Abstract
A unique frequency synthesizer unit for use in a data processing system I/O interface unit for providing at least one clock signal having a substantially constant frequency which can be generated in response to any one of a plurality of input clock signals each having a different frequency. The system I/O interface unit may be used, for example, to control communication between a system bus and a plurality of I/O buses having different timing and operating characteristics. The system I/O interface unit may be used, for example, to control communication between a system bus and a plurality of I/O buses having different timing and operating characteristics.
