Abstract
One embodiment relates to a clocking network interconnecting an array of transceivers. The clocking network includes first and second series of multiplexers, each multiplexer in the first and second series being adjacent to a transceiver. The first series of multiplexers selectively transmits clock signals in a first direction of the array, and the second series of multiplexers selectively transmits clock signals in a second direction of the array. Another embodiment relates to an integrated circuit with a programmable interface. The integrated circuit includes an array of physical media attachment circuits, phase-locked loop circuits, and a clock distribution network. The clock distribution network is arranged to be programmed into multiple segments. Each segment distributes a clock signal to a bounded range of the physical media attachment circuits in the array. Another embodiment relates to a method of distributing clock signals in an integrated circuit. Other embodiments and features are also disclosed.
