  • Abstract
    This paper describes a wide-range programmable frequency synthesizer building block for 4.25Gbps serial link applications. A unique feature of the design is the use of variable gain charge pumps to adjust loop gain as well as damping in order to minimize output jitter. The synthesizer architecture includes pre and post dividers to maximize programmability. A novel implementation of the high speed divide circuit is also described
