Abstract
Circuits for distributing a global clock signal to all clock sinks on a chip for synchronous operation comprises 1) a plurality of synchronous clock areas (SCA), each SCA having a Time-Average-Frequency Direct Period Synthesis (TAF-DPS) clock source for generating a function clock, said TAF-DPS clock source has frequency synthesis and phase adjustment capabilities on its output of function clock; 2) a network for distributing a low frequency global clock signal to said plurality of synchronous clock areas, said global clock signal is used as reference for said TAF-DPS clock sources in all SCAs; 3) a plurality of clock sinks in each SCA, said clock sinks are driven by said function clock generated from said TAF-DPS clock source. Methods of distributing a low frequency global clock signal to all clock sinks in a chip for synchronous operation are also disclosed.
