摘要:
A novel clock splitter that has a local internal clock frequency-divider is presented. The clock splitter comprises an oscillator clock splitter, wherein the oscillator clock splitter splits an oscillator clock signal into a B clock and a C clock; a clock frequency-divider, wherein the clock frequency-divider selectively suppresses clock pulses in the C clock to generate a slower C clock signal that is slower than the oscillator clock; and a B/C clock order logic, wherein the B/C clock order logic phase shifts the C clock relative to a B clock. The clock frequency-divider may selectively suppress pulses in the B clock to generate a slower B clock signal. The slower B and C clock signals may have a same or different frequency. In one embodiment, the clock splitter is located at a terminal leaf of a clock tree.
