Abstract
Methods and circuitry for distributing and synchronizing a divided clock signal in an electronic device are disclosed. In one aspect of an embodiment, a series of registers distributes the divided clock signal and the series of registers is clocked by a full-speed clock signal from which the divided clock signal is derived. In another aspect, the divided clock signal and the full-speed clock signal are distributed to IO circuitry of the electronic device. In yet another aspect, the divided clock signal is also distributed to circuitry in a core of the electronic device.
