Patent number: 10313091Abstract: Currently, there exists low power Ethernet PHY solutions running at 10 Gbps over twin-ax cables with SFP+ connectors. However, the cost and range of these cables, along with the size of the connectors, do not match the requirements of in-vehicle networks. If the cable is replaced with a single pair of shielded or coaxial cables, a different mechanism is needed to provide bi-directional communication. Time division duplexing (TDD) can be used to emulate full duplex communication over the single pair of cables by taking turns, in time, transmitting data over the pair of cables in each direction.Type: GrantFiled: April 21, 2016Date of Patent: June 4, 2019Assignee: Avago Technologies International Sales Pte. LimitedInventors: Ahmad Chini, Mehmet V. Tazebay

Patent number: 10205539Abstract: The present disclosure is directed to apparatuses for preventing significant amounts of common mode noise from a PHY transceiver, such as an Ethernet PHY transceiver, from coupling to an unshielded twisted-pair cable. The apparatuses can provide common mode noise isolation, while limiting any common mode noise to differential mode noise (CM-DM) conversion. Common mode noise is generally ignored by a PHY transceiver that receives a differential data signal because of differential signaling. However, when common mode noise is converted to differential mode noise, then data errors can result. Thus, limiting any CM-DM conversion is important.Type: GrantFiled: December 20, 2016Date of Patent: February 12, 2019Assignee: Avago Technologies International Sales Pte. LimitedInventors: Ahmad Chini, Mehmet V. Tazebay

Publication number: 20160241437Abstract: Automotive area networks (AAN) have a substantially fixed network topology, meaning that the physical media used for communications between devices included in the AAN is known. For example, the physical connections within an AAN, sometimes provided by wiring harnesses, can include fixed lengths of twisted pairs of wire (“twisted pairs”). Pre-compensation parameters related to characteristics of the twisted pairs can be determined at the factory, and loaded into the memory of devices connected to the AAN. These pre-compensation parameters are used to improve the fast wake up and link acquisition times of connected devices. Various characteristics of the physical communication channel are measured or estimated as a function of mechanical, ingress, climactic, and environmental variations (MICE), and used to update the pre-compensation parameters.Type: ApplicationFiled: April 28, 2016Publication date: August 18, 2016Applicant: BROADCOM CORPORATIONInventors: Wael William Diab, Mehmet V.

Transceiver self-diagnostics for electromagnetic interference (EMI) degradation in balanced channels
Patent number: 9379772Abstract: Transceiver self-diagnostics for electromagnetic interference (EMI) degradation in balanced channels. Selective operation of transmitting a common mode signal from a communication link implemented for supporting differential signaling, and appropriate processing of any detected signal energy, such as that corresponding to differential signal energy, provides a measure of electromagnetic compatibility (EMC) corresponding to the communication link. Comparison of detected differential signal energy to one or more thresholds may provide indication of whether or not the communication link is balanced or unbalanced, a degree or margin with which the communication link is compliant in accordance with EMC in accordance with one or more protocols, standards, or recommended practices. Multiple successive measurements of detected differential signal energy may be used to determine a trend of performance, such as whether or not the communication link is trending toward imbalance, failure, or noncompliance.Type: GrantFiled: March 27, 2015Date of Patent: June 28, 2016Assignee: BROADCOM CORPORATIONInventors: Scott R.

Patent number: 8935550Abstract: A method and system to dynamically manager power in a communication system are provided herein. The method comprises the steps of monitoring a transmit data queue once every first pre-determined period of time and determining whether the transmit data queue is empty for a pre-determined number of times. The method further includes the step of generating a transition state signal to stop de-queuing of data from the transmit queue if the transmit data queue is empty for the pre-determined number of times and selectively operating portions of a Physical Layer (PHY) that are used for functions other than transmitting and receiving an idle signal in a low power mode.Type: GrantFiled: September 19, 2011Date of Patent: January 13, 2015Assignee: Broadcom CorporationInventors: Mehmet V.
