Patent number: 9225370Abstract: Communication devices coupled via a communication link may comprise physical layer devices that may be operable to determine presence of a received signal and to mitigate noise in the signal prior to processing and/or validating the signal. Analog and/or digital signal processing may be utilized to process the signal and/or mitigate noise in the signal. Noise mitigation may comprise near-end crosstalk cancelling and/or echo cancelling and/or may utilize local transmit signal information. Subsequent to noise mitigation, samples of the noise reduced signal may be accumulated and/or an average signal strength and/or average signal power level may be determined. The average signal strength and/or average signal power level may be compared to one or more thresholds which may be configurable and/or programmable.Type: GrantFiled: March 12, 2015Date of Patent: December 29, 2015Assignee: BROADCOM CORPORATIONInventors: Mehmet Tazebay, Scott Powell, Peiqing Wang, Bruce Conway, Sang Bui

Patent number: 9215092Abstract: An Ethernet PHY may receive an indication from a local timing source that a local clock is suitable for propagation to a link partner. In response, a timer in the Ethernet PHY may be started. In instances that the Ethernet PHY receives, during a time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, the Ethernet PHY may be configured as timing slave. In instances that the Ethernet PHY does not receive, during the time period subsequent to starting the timer and before the timer reaches a predetermined value, an indication that the link partner is propagating a clock that is suitable for the Ethernet PHY to synchronize to, Ethernet PHY may be configured as timing master upon the timer reaching the predetermined value.Type: GrantFiled: June 10, 2011Date of Patent: December 15, 2015Assignee: Broadcom CorporationInventors: Xiaotong Lin, Mehmet Tazebay, Peiqing Wang

Patent number: 9215168Abstract: Systems and methods for implementing controller area network (CAN) communications between CAN nodes using Ethernet are provided. An Ethernet switch includes ports, each of which is configured to receive an Ethernet data packet (EDP) from a CAN node. Each EDP includes a CAN message, which includes an identification (ID) of a corresponding CAN node. A first port is configured to receive a first EDP and a second port is configured to receive a second EDP. The Ethernet switch also includes a controller module configured to detect a CAN conflict between the first EDP and the second EDP. The controller module is configured to select, in response to the detection of the CAN conflict, the first EDP or the second EDP based on the ID corresponding to the first EDP and the ID corresponding to the second EDP. The controller module is configured to route the selected EDP to a destination.Type: GrantFiled: December 17, 2012Date of Patent: December 15, 2015Assignee: Broadcom CorporationInventors: Yongbum Kim, Mehmet Tazebay, Kevin Brown, Manfred Wagner

Patent number: 9001714Abstract: An Ethernet physical layer device using time division duplex. A time division duplex frame can be defined with uplink and downlink transmission periods. These defined uplink and downlink transmission periods can be adjusted based on bandwidth and latency considerations on the network link.Type: GrantFiled: November 21, 2011Date of Patent: April 7, 2015Assignee: Broadcom CorporationInventors: Ahmad Chini, Mehmet Tazebay, Scott Powell

Patent number: 8885506Abstract: Energy efficient Ethernet with asymmetric low power idle. Low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Such a requirement reduces the application of low power idle due to the frequent existence of data traffic in only one direction. An asymmetric low power idle mode enables reduction in power consumption and signal emissions even when one direction has data traffic to transmit.Type: GrantFiled: May 23, 2012Date of Patent: November 11, 2014Assignee: Broadcom CorporationInventors: Ahmad Chini, Mehmet Tazebay

Patent number: 8856570Abstract: Energy efficient Ethernet with a low power active idle transmission mode. A low power active idle transmission mode is defined for the transmission of idle signals during inter-packet gaps. The low power active idle transmission mode can provide energy savings in those instances that preclude the use of a low power idle mode and/or subrating to produce greater energy savings.Type: GrantFiled: August 31, 2011Date of Patent: October 7, 2014Assignee: Broadcom CorporationInventors: Wael William Diab, Mehmet Tazebay, Scott Powell

Patent number: 8718084Abstract: A system and method for dynamic power control for energy efficient physical layer communication devices. Energy-efficiency features are continually being developed to conserve energy in links between such energy-efficient devices. These energy-efficient devices interoperate with many legacy devices that have already been deployed. In these links, energy savings can be produced by having a local receiver enter an energy saving state based upon the receipt of standard IDLE signals.Type: GrantFiled: September 27, 2012Date of Patent: May 6, 2014Assignee: Broadcom CorporationInventors: Mehmet Tazebay, Scott Powell, Peiqing Wang

Patent number: 8621255Abstract: A system and method for loop timing update of energy efficient physical layer devices using subset communication techniques. During a quiet period during which a subset of communication channels are transitioned from an active mode to a low-power mode, circuitry in the active channel can be designed to track, on behalf of the inactive channels, the phase drift due to the frequency offset. This tracking of the frequency estimation error would reduce the time required to perform a timing update for the communication channels when transitioning back to the active mode.Type: GrantFiled: March 29, 2010Date of Patent: December 31, 2013Assignee: Broadcom CorporationInventors: Peiqing Wang, Linghsiao Wang, Mehmet Tazebay, Scott Powell

Patent number: 8565270Abstract: A first PHY may be coupled to a second PHY via a network link. The first PHY may transition from a role of timing master for the network link to a role of timing slave for the network link. During a first time interval subsequent to the transition, the PHYs may communicate half-duplex over the link while the first PHY synchronizes to a transmit clock of the second PHY. During a second time interval, the PHYs may communicate full-duplex while the second Ethernet PHY synchronizes to a transmit clock of the first PHY. Also during the second time interval, the first PHY may determine that the first PHY and the second PHY are synchronized. Subsequent to the determination, the PHYs may begin full-duplex communication of data on the network link.Type: GrantFiled: June 8, 2011Date of Patent: October 22, 2013Assignee: Broadcom CorporationInventors: Peiqing Wang, Xiaotong Lin, Mehmet Tazebay, Linghsiao Wang
