Publication number: 20240103595Abstract: High-speed data communication devices, e.g., repeaters, interfacing between a host and a peripheral operate such that high-speed components except for a host-side squelch detector are set or maintained in a deactivated state during an idle period of a micro frame. In an example, a start of a micro frame is detected on a data bus during a first time period. In a second time period after the first time period, the high-speed communication device determines whether at least one data packet is contained in the micro frame. When it is determined during the second time period that no data packet is contained in the micro frame, active components, except a squelch detector, are controlled to be inactive during a third time period after the second time period.Type: ApplicationFiled: December 11, 2023Publication date: March 28, 2024Inventors: Mustafa Ulvi Erdogan, Suzanne Mary Vining, Bharath Kumar Singareddy, Douglas Edward Wente

Patent number: 11792361Abstract: A redriver system adapted for coupling to a first device and to a second device includes first and second transmitter drivers and a snoop circuit. The first transmitter driver has a first enable input. The second transmitter driver has a second enable input. The snoop circuit is coupled to the first and second enable inputs. The snoop circuit is configured to determine whether the first device and the second device are to operate according to a first protocol. Responsive to the snoop circuit determining that the first and second devices are to operate according to the first protocol, the snoop circuit enables the first transmitter driver and disables the second transmitter driver. Responsive to the snoop circuit determining that the first and second devices are not to operate according to the first protocol, the snoop circuit disables the first transmitter driver and enables the second transmitter driver.Type: GrantFiled: June 30, 2021Date of Patent: October 17, 2023Assignee: Texas Instruments IncorporatedInventors: Charles Michael Campbell, Mustafa Ulvi Erdogan, Douglas Edward Wente, Sridhar Ramaswamy

Publication number: 20220206983Abstract: A method of operating an embedded universal serial bus (eUSB) repeater includes holding an eUSB receiver and a USB transmitter in active states and holding a USB receiver and an eUSB transmitter in standby states. The method includes receiving by the eUSB receiver a token packet indicative of transmission of a first downstream packet, and transitioning the USB receiver and the eUSB transmitter from the standby states to the active states responsive to the token packet. The method includes transmitting the token packet by the USB transmitter. The method includes receiving by the eUSB receiver a downstream packet or receiving by the USB receiver an upstream packet within a first timeout period after receiving the token packet, and transmitting the downstream packet by the USB transmitter or transmitting the upstream packet by the eUSB transmitter.Type: ApplicationFiled: October 15, 2021Publication date: June 30, 2022Inventors: Mustafa Ulvi Erdogan, Bharath Kumar Singareddy, Suzanne Mary Vining, Srijan Rastogi, Sirish Oruganti, Douglas Edward Wente

Patent number: 11153135Abstract: Methods and systems of adaptive equalization to compensate channel loss are disclosed. A method includes detecting a peak amplitude of an equalizer output signal and selecting a set of reference voltage levels from M sets based on the peak amplitude of the equalizer output signal, each of the M sets having N reference voltage levels. The method includes continuing to increase an equalization level in predetermined steps to a next higher equalization level if the applied equalization level does not correspond to the over-equalization level and evaluating the distribution of the resulting hit counts for each increase to the next higher equalization level until the applied equalization level corresponds to the over-equalization level. The method includes decreasing to the previously applied lower equalization level if the applied equalization level corresponds to the over-equalization level.Type: GrantFiled: January 11, 2021Date of Patent: October 19, 2021Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Shita Guo, Yanli Fan, Mustafa Ulvi Erdogan, Douglas Edward Wente
