Patent number: 11669475Abstract: An isolating repeater and corresponding method for Universal Serial Bus (USB) communications. The isolating repeater includes, on either side of a galvanic isolation barrier, front end circuitry coupled to a pair of external terminals, a full speed (FS) transceiver adapted to drive and receive signals over one or more FS isolation channels, and a high speed (HS) transceiver adapted to drive signals over a one HS isolation channel and receive signals over another HS isolation channel. The front end circuitry encodes received signals corresponding to HS data into two-state signals for transmission over one HS isolation channel, and encodes received signals corresponding to HS signaling into two-state signals for transmission over one or more of the FS isolation channels.Type: GrantFiled: April 30, 2021Date of Patent: June 6, 2023Assignee: Texas Instruments IncorporatedInventors: Anant Shankar Kamath, Rakesh Hariharan, Mark Edward Wentroble

Publication number: 20230111096Abstract: In an example, a method of operating a repeater having an isolation barrier to isolate a host side of the repeater from a peripheral side of the repeater, the repeater operable to be coupled to a universal serial bus (USB), includes causing the host side to enter into a suspend mode. The method also includes, responsive to entering the suspend mode, disabling a host isolation transceiver at the host side. The method includes periodically enabling the host isolation transceiver to transmit a data signal from the host side to the peripheral side. The method includes exiting the suspend mode. The method also includes enabling the host isolation transceiver.Type: ApplicationFiled: April 28, 2022Publication date: April 13, 2023Inventors: Rakesh HARIHARAN, Tarunvir SINGH, Anant Shankar KAMATH, Mark Edward WENTROBLE, Christopher Joseph RODRIGUES, Prajwala PUTTAPPA

Publication number: 20220391217Abstract: A serial bus repeater includes first and second ports adapted to be coupled to respective devices. A first termination resistor network couples to the first port. A second termination resistor network couples to the second port. A squelch detect circuit couples to the first bus port and is configured to detect activity on the first bus and to generate a squelch signal responsive to detection of activity on the first port. A first state machine is configured to: determine an elapsed time during which the squelch signal indicates activity on the first port; determine that the elapsed time exceeds a first threshold; and, responsive to the determination that the elapsed time exceeds the first threshold, assert configuration signals to reconfigure the first and second termination resistor networks.Type: ApplicationFiled: November 8, 2021Publication date: December 8, 2022Inventors: Mark Edward WENTROBLE, Anant Shankar KAMATH, Rakesh HARIHARAN, Prajwala P, Suzanne Mary VINING

Patent number: 10880117Abstract: Two CAN bus transceivers utilized in a single integrated circuit package with the CAN bus connections between the two transceivers being inverted. Thus, one transceiver is connected to the CAN bus high and low lines while the other transceiver is connected to the CAN bus low and high lines. Both transceivers power up in a standby condition and each transceiver is monitoring for wake up signals on the CAN bus. The transceiver that is correctly connected to the CAN bus detects wake up signals. When the wake up signals are detected at that transceiver, that transceiver is brought to full operating state and the other transceiver is placed in a full standby condition. Additional input resistance is provided with each transceiver to maintain the proper input resistance for the integrated circuit.Type: GrantFiled: December 10, 2019Date of Patent: December 29, 2020Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Abhijeeth Aarey Premanath, Richard Edwin Hubbard, Maxwell Guy Robertson, Lokesh Kumar Gupta, Mark Edward Wentroble, Roland Sperlich, Dejan Radic
