Abstract
A PLL with a power supply voltage referenced loop filter for UltraSPARC microprocessor clock generation has measured ±25 ps cycle-to-cycle jitter at 1.9 V and 360 MHz. The operating frequency range is from 8.5 MHz to 660 MHz and lowest power supply is 1.35 v at 400 MHz. The power supply noise rejection of 1.3 ps/50 mv is achieved. The measured cycle-to-cycle jitter for 400 mVpp sinusoidal AC signal at power supply of 1.9 V is ±37 ps
