SYSTEM-ON-A-CHIP CLOCK PHASE MANAGEMENT USING FRACTIONAL-N PLLS

A clock distribution architecture is provided in which the output clock signals from a plurality of fractional-N PLLs have a known phase relationship because each fractional-N PLL is configured to commence a phase accumulation responsive to a corresponding edge of a reference clock signal.
