Patent number: 9035484Abstract: A powerline communication (PLC) transmission module transmits a signal over a three-line electrical mains supply. The PLC transmission module includes at least two coupling transformers, each transformer coupling the signal to first and second line-pairs of a three-line electrical mains supply, the first and second line-pairs different from one another. Driving circuitry drives a first version of the signal over the first line-pair and a second version of the signal over the second line-pair. Inversion circuitry selectively inverts one version of the signal relative to the other version of the signal, dependent upon an enacted transmission mode. The inversion circuitry may invert neither/both of the versions of the signal so that the signal is transmitted as a differential-mode signal on the line-pairs or invert one of the first and second versions of the signal relative to the other so that the signal is a common-mode signal.Type: GrantFiled: December 13, 2011Date of Patent: May 19, 2015Assignee: Broadcom CorporationInventors: Jonathan Ephraim David Hurwitz, Seyed A A Danesh, Iain Barnett

Patent number: 8711951Abstract: A method for operating a Power Line Communications (PLC) device includes identifying at least one proximately located load device using the wireless interface, determining device characteristics of the at least one proximately located load device using the wireless interface, communicating with a remote PLC device via the PLC interface, and transmitting to the remote PLC device via the PLC interface the device characteristics of the at least one proximately located load device. Operation may further include establishing wireless communications with the at least one proximately located device, querying the at least one proximately located device wirelessly, and receiving the device characteristics wirelessly. Other operations include creating a diagrammatic representation of a premises representing a plurality of areas and passages between the plurality of areas and including wireless reception quality for each of the plurality of spaces.Type: GrantFiled: March 30, 2012Date of Patent: April 29, 2014Assignee: Broadcom CorporationInventors: Jonathan Ephraim David Hurwitz, Seyed A A Danesh, Juan Carlos Riveiro Insua

Patent number: 8711952Abstract: An analog to digital converter with increased sub-range resolution. The device includes an analog front end that produces an analog communication signal, a digital front end that receives a digital communication signal, and an Analog to Digital Converter (ADC) that samples the analog communication signal across a full-range. The ADC includes a full-range ADC having a first quantization accuracy configured to sample the analog communication signal across the full-range and a central sub-range ADC having a second quantization accuracy greater than the first quantization accuracy and configured to sample the analog communication signal across a central sub-range of the full-range. The ADC also includes signal combining circuitry configured to process outputs of the full-range ADC and the central sub-range ADC to create the digital communication signal.Type: GrantFiled: June 24, 2013Date of Patent: April 29, 2014Assignee: Broadcom CorporationInventors: Keith Findlater, Seyed A A Danesh, Jonathan Ephraim David Hurwitz

Patent number: 8552901Abstract: An analog-to-digital converter (ADC) includes a plurality of single slope ADCs, a ramp generator, and digital output circuitry. Each single slope ADC includes an analog input operable to receive an analog input signal, a ramp input operable to receive an analog ramp signal, a comparator operable to compare the analog input signal to the analog ramp signal, and an output operable to produce a digital representation of the analog input signal based upon the comparison, wherein the plurality of single slope ADCs are operable to receive analog ramp signals that are out of phase with each other. The ramp generator that is operable to generate analog ramp signals for each of the plurality of single slope ADCs. The digital output circuitry is operable to receive outputs from each of the plurality of single slope ADCs and to produce a digital representation of the analog input signal based thereupon.Type: GrantFiled: August 22, 2011Date of Patent: October 8, 2013Assignee: Broadcom CorporationInventors: Seyed A A Danesh, Jonathan Ephraim David Hurwitz
