Abstract
A configurable clock buffer including first and second buffers and isolation circuitry. The first buffer has an input coupled to a clock input node and has an output coupled to a clock output node. The second buffer has an input coupled to an intermediate input node and has an output coupled to an intermediate output node. The isolation circuitry is responsive to at least one mode signal, in which it electrically couples the intermediate input node to the clock input node and electrically couples the intermediate output node to the clock output node when the at least one mode signal is in a first state, and in which it electrically couples the intermediate input node to a static node and electrically isolates the intermediate output node from the clock output node when the at least one mode signal is in a second state.
