Latest Patents

Hagan holds a patent for a "Dual-mode receiver termination detection circuit." This invention relates to a receiver termination detection circuit designed for wireline datalinks. The transmitter circuit includes positive and negative output nodes that are coupled through a channel to a receiver. The detection circuit features programmable pull-up and pull-down resistors connected to the output nodes, along with voltage comparators that have independent reference voltage inputs. A mode selection input allows for the selection between single-ended and differential detection modes. Control logic drives the output nodes concurrently in single-ended mode and differentially in differential mode. The comparator outputs are sampled after a programmable time delay to detect receiver termination. This circuit supports both AC-coupled single-ended and DC-coupled differential termination detection while maintaining common-mode voltage during transitions to normal operation.
