Latest Patents

Don Barnetson holds a patent for a PCIe retimer with a reduced power low latency mode. This innovative retimer includes an upstream interface with an upstream receiver that converts a downlink signal into a downlink symbol stream. Additionally, it features a downstream interface with a downstream transmitter that provides a transmit signal representing the downlink symbol stream. The core circuitry consists of a downstream path and a downstream bypass path, along with a controller. The downstream path is designed to convey the downlink symbol stream from the upstream receiver to the downstream transmitter through various clock domain components. The downstream bypass path can convey the downlink symbol stream without any core clock domain components, and the controller is responsible for disabling the clock signal for the transmit clock domain component when the downstream bypass path is enabled.
