Latest Patents

One of Sanjeev Chopra's latest patents is focused on an oversampling CDR that compensates for frequency differences without the need for an elasticity buffer. This invention presents a method, algorithm, architecture, circuit, and system designed to address frequency discrepancies in oversampled CDRs. The system utilizes a programmable divider, which alters its division ratio for one or more cycles when accumulated phase movement exceeds a predetermined threshold. This advancement allows for a significant reduction in the size of the elasticity buffer, or even its complete elimination, leading to decreased area requirements and a minimized dependence on maximum allowed burst size based on parts per million (ppm) differences. The programmable threshold enhances robustness against high-frequency jitter, making this technology particularly valuable in high-speed data applications.
