Publication number: 20150149654Abstract: A system may include a first stage comprising first signaling components for a first protocol, and a second stage comprising second signaling components for the first protocol and a second protocol. The system may further include logic configured to receive an incoming data stream, and determine a stream protocol for the data stream. The logic may be further configured to, responsive to the determination, activate the at least a portion of the first stage when the stream protocol is compliant with the first protocol, and when the stream protocol is compliant with the second protocol, deactivate the first stage.Type: ApplicationFiled: December 18, 2013Publication date: May 28, 2015Applicant: Broadcom CorporationInventors: Davide Vecchi, Jan Mulder, Franciscus Maria Leonardus Van der Goes, Erol Arslan, Michael Randall Grimwood

Patent number: 8760212Abstract: A level shifter and method are disclosed. In one embodiment, the level shifter includes a DC biasing component connected with both an AC coupling component and a high voltage output amplifier. The AC coupling component receives an input signal from a low voltage domain and output a first voltage signal. The DC biasing component is configured to bias the first voltage signal using a bias voltage based on a previous output signal in a high voltage domain. The high voltage output amplifier is configured to amplify the DC biased voltage signal in the high voltage domain and provide an output signal in the high voltage domain.Type: GrantFiled: October 31, 2012Date of Patent: June 24, 2014Assignee: Broadcom CorporationInventor: Erol Arslan

Patent number: 8446184Abstract: An output stage comprising a current mode line driver, a voltage mode line driver, and a center-tapped transformer for coupling data provided by the line drivers to a transmission line is provided herein. The output stage is configured to operate in a backwards compatible Ethernet communication device. For example, the Ethernet communication device is configured to support 10G Ethernet and legacy Ethernet modes of 10BASE-T, 100BASE-T, and 1000BASE-T. The current mode line driver can be utilized while operating in the 10G Ethernet mode to provide high linearity. The voltage mode line driver can be utilized while operating in legacy mode to conserve power. In order to accommodate the use of two different line drivers, a switch and/or a voltage regulator is used to couple/decouple a dc voltage to a center-tap of the transformer based on which of the two different line drivers is currently active.Type: GrantFiled: August 12, 2010Date of Patent: May 21, 2013Assignee: Broadcom CorporationInventors: Frank Van Der Goes, Christopher Ward, Ovidiu Bajdechi, Erol Arslan

Patent number: 7551035Abstract: A voltage domain crossing circuit and method are disclosed. In one embodiment, the voltage domain crossing circuit comprises an AC coupling component, a DC biasing component and a high voltage output amplifier. The AC coupling component receives an input low voltage signal and AC couples and splits the signal into two voltages. The two voltages are then DC biased to a predetermined bias voltage using the DC biasing component. The high voltage output amplifier then amplifies the biased voltages in the high voltage domain yielding a signal in the high voltage domain. Other embodiments of the voltage domain crossing circuit and method are also disclosed.Type: GrantFiled: August 24, 2006Date of Patent: June 23, 2009Assignee: Broadcom CorporationInventors: Jan Roelof Westra, Franciscus Maria Leonardus van der Goes, Erol Arslan

Patent number: 7199737Abstract: A system and method for an improved analog front-end system is disclosed. By coupling a switch to the output of a track-and-hold circuit and to the input of a time-discrete circuit, such as an analog-to-digital converter, the time-discrete circuit can be disconnected from the track-and-hold circuit during the track mode of the track-and-hold circuit. This improved system reduces the load of the T/H circuit from the full input capacitance of the time-discrete circuit to the smaller parasitics of the switch thereby providing a T/H circuit with lower power consumption and smaller area while maintaining high speed and high accuracy.Type: GrantFiled: June 2, 2004Date of Patent: April 3, 2007Assignee: Broadcom CorporationInventor: Erol Arslan
