Patent number: 11909554Abstract: An Ethernet transceiver is disclosed. The Ethernet transceiver includes transceiver circuitry to couple to one end of an Ethernet link. The transceiver circuitry includes transmit circuitry to transmit high-speed Ethernet data along the Ethernet link at a first data rate and receiver circuitry. The receiver circuitry includes adaptive filter circuitry and correlator circuitry. The receiver circuitry is responsive to an inline signal to operate in a low-power alert mode with the adaptive filter circuitry disabled and to receive alert signals from the Ethernet link simultaneous with transmission of the Ethernet data by the transmit circuitry. The alert signals are detected by the correlator circuitry and include a sequence of alert intervals exhibiting encoded data at a second data rate less than the first data rate.Type: GrantFiled: October 11, 2022Date of Patent: February 20, 2024Assignee: Marvell Asia Pte, Ltd.Inventors: Saied Benyamin, Seid Alireza Razavi Majomard

Patent number: 11711224Abstract: An Ethernet transceiver is disclosed. The Ethernet transceiver includes transceiver circuitry having receiver circuitry to receive refresh signals during corresponding refresh cycles from a link partner during a low-power idle mode of operation. Each refresh signal has a refresh period, and where a quiet period is interposed between successive refresh cycles. Signal quality detection circuitry, during the low-power idle mode, determines a measure of signal quality associated with the received refresh signals. Subsequent refresh cycles exhibit at least one of an adjusted refresh period or an adjusted quiet period based on the measure of signal quality.Type: GrantFiled: April 6, 2021Date of Patent: July 25, 2023Assignee: MARVELL ASIA PTE LTDInventors: Saied Benyamin, Seid Alireza Razavi Majomard

Patent number: 7818649Abstract: A decoder and method for implementing an iterative error correcting decoder are provided for decoding a codeword consisting of a N-bit messages. In one implementation, the decoder includes a first set of nodes, and a second set of nodes, each having N bits of resolution. Each node of the second set is coupled to at least one node of the first set, each node of the second set being coupled to a node of the first set by a corresponding set of M wires. Each of the first set of nodes is operable to transfer the bits of a given N-bit message of the codeword over the corresponding set of M wires to a coupled node of the second set during a single iteration cycle, each of the M wires carrying i bits, where N is an integer greater than M, and N=M*i.Type: GrantFiled: November 30, 2006Date of Patent: October 19, 2010Assignee: Aquantia CorporationInventors: Ramin Farjadrad, Saied Benyamin

Patent number: 6531931Abstract: A circuit and method for equalization of a communication signal received over a communication system transmission line using switched filter characteristics. Equalization for frequency-independent and frequency-dependent attenuation of the communication signal is accomplished with a linear equalization channel which includes an input biasing circuit which provides a common input signal to two parallel amplifier paths. One path includes a wideband, fixed-gain, frequency-independent amplifier stage. The other path is a wideband multiplier amplifier stage in series with a wideband, frequency-dependent amplifier stage having a switchable high-pass characteristic. The outputs of the fixed-gain wideband frequency-independent amplifier stage and wideband, frequency-dependent amplifier stage having a switchable high-pass characteristic are both tied in common to the input of a wideband gain buffer amplifier stage, which has a switchable high-frequency boost frequency response characteristic.Type: GrantFiled: May 28, 1999Date of Patent: March 11, 2003Assignee: Agere Systems Inc.Inventors: Saied Benyamin, Michael Arthur Brown, Ramin Shirani

Patent number: 6188721Abstract: An improved adaptive equalizer providing the proper amount of equalization to restore the missing frequency components of a received and underequalized waveform. The invention'equalization gain or pulse counting feature can be set at various levels by digitally programming the control logic of the invention. Additionally, the digital control features of the invention permit higher accuracy in determining required equalizations for waveforms and avoid variations, such as temperature process variations, present in analog systems. The invention permits higher accuracy in determining required equalizations for waveforms. The invention finds, holds, and updates the average low frequency peak of the incoming signal in a highly digital manner. Since peak information is digitally held, it is not subject to the data dependent drifts inherent in analog peak detectors.Type: GrantFiled: April 17, 1998Date of Patent: February 13, 2001Assignee: Lucent Technologies, Inc.Inventors: Ramin Shirani, Saied Benyamin, Michael A.

Patent number: 6148025Abstract: An improved invention providing a solution to a problem endemic to conventional adaptive equalizer systems, a problem known as baseline wander. The invention brings the baseline back down when it has drifted up due to baseline wander. The invention brings the baseline back up when it has drifted down due to baseline wander. The end result is that the invention keeps the data centered about the common mode, thus helping to ensure that the data is equalized properly without distortion.Type: GrantFiled: April 17, 1998Date of Patent: November 14, 2000Assignee: Lucent Technologies, Inc.Inventors: Ramin Shirani, Saied Benyamin, Michael A.
