Abstract:
1. A digital system, comprising: a global distribution network to carry a reference clock; and a plurality of circuit domains coupled to the global distribution network to receive the reference clock for synchronous operation in accordance with the reference clock; wherein each circuit domain of the plurality of circuit domains comprises: a respective clock generator driven by the reference clock to generate a local resonant clock signal; a respective local network discrete from the local networks of the other circuit domains and coupled to the clock generator to distribute the local resonant clock signal within the circuit domain; respective circuitry coupled to the local network to operate in accordance with the local resonant clock signal, the circuitry and the local network presenting a capacitive load for the local resonant clock signal; and a respective inductance coupled to the local network to resonate the capacitive load independently of the capacitive loads of the other circuit domains for resonant distribution of the local resonant clock signal within the circuit domain.
