Abstract :
This multi-GHz clock generation and distribution scheme enables the NetBurst/sup TM/ micro-architecture of Pentium(R) 4 microprocessor. A low-skew and jitter and low-power solution is achieved for three separate core and I/O bus frequencies for a total of six different clock frequencies running concurrently. A debug-friendly clocking environment provides easy observability, testing, and reconfiguration features, enabling rapid time to market.
