Publication number: 20220103000Abstract: A method includes determining a charging port mode by receiving a data contact detect (DCD) Complete signal, reducing a voltage on a first data pin of a Universal Serial Bus (USB) connector of a portable device, and determining that a condition is true when a voltage on a second data pin of the USB connector is equal to or greater than 0.8 to 2.0 Volts (V), and is false otherwise. When the condition is true, a first signal is sent on a control circuit output indicating indicate that the PD is connected to a dedicated charging port (DCP) of Divider 0 mode. When the condition is false, a second signal is sent on the control circuit output indicating that the PD is connected to a DCP of 1.2V short mode.Type: ApplicationFiled: September 24, 2021Publication date: March 31, 2022Inventor: Suzanne Mary VINING

Publication number: 20220094577Abstract: 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: ApplicationFiled: August 13, 2021Publication date: March 24, 2022Inventors: Suzanne Mary VINING, Amit S. RANE, Charles Michael CAMPBELL

Patent number: 11281284Abstract: A method includes detecting a micro start of frame packet (?SOF) on a data bus. If there is at least one data packet contained in a microframe during the first threshold period after the ?SOF, transmitters are held in an active state. If there is no data packet in the first threshold period after the ?SOF, the transmitters are transitioned from the active state to an OFF state. The method also includes transitioning the transmitters from the OFF state to the active state prior to a switchback period before the end of the microframe. The method also includes transitioning the transmitters from the OFF state to the active state if a data packet is received in the OFF state. The method also includes dropping the data packet received in the OFF state and transitioning from the OFF state to the active state when the data packet is dropped.Type: GrantFiled: December 17, 2019Date of Patent: March 22, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Suzanne Mary Vining, Douglas Edward Wente, Win Naing Maung, Julie Marie Nirchi
