Patent number: 11843484Abstract: A system for selecting an equalizer setting of an equalizer to equalize signals received via a communications link. Starting with a first (e.g., minimum) equalizer setting and a threshold voltage near the mid-eye voltage of the equalized output signal, the system estimates the amplitude of the inner eye of the equalized output signal by comparing the equalized output signal to a series of threshold voltages. If the amplitude of the equalized output signal is less than ideal, the system dynamically increases the equalizer setting. The system quickly converges on the equalizer setting for the communication link because, rather than comparing the output signal at every voltage offset using every equalizer setting, the system only evaluates the equalizer settings necessary to select the equalizer setting for the communications link and uses only the voltage offsets necessary to evaluate each equalizer setting.Type: GrantFiled: October 14, 2022Date of Patent: December 12, 2023Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Suzanne Mary Vining, Amit S.

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

Patent number: 11765811Abstract: Embodiments of a laser system having an extremely large number of small pulsed lasers for irradiating small targets in inertial confinement fusion experiments, high energy density physics experiments, and inertial fusion power plants is more flexible than existing laser systems. Embodiments facilitate finer control of critical features of laser pulses for inertial fusion, as well as significant reduction in development costs and expansion of the community involved in the research relative to existing laser systems. Embodiments produce smooth intensity profiles at the target, large bandwidth that is over two orders of magnitude greater than existing laser systems, and fine control over laser wavelengths, focal properties, temporal pulse shape, and illumination geometry. Properties of each of the small pulsed lasers are individually selectable.Type: GrantFiled: May 18, 2020Date of Patent: September 19, 2023Assignee: Logos Technologies HoldCo, Inc.Inventors: E.
