Patent number: 10727838Abstract: Power conservation in a phase locked loop (PLL) places the PLL into a low-power mode and periodically reactivates the PLL to prevent leakage current from causing a voltage controlled oscillator (VCO) within the PLL to drift. The PLL also includes an adjustable delay circuit positioned between an output of the VCO and an input of a phase detector, where the delay circuit is used to adjust phase slew of a feedback signal to help the PLL settle into a desired frequency. By controlling the drift of the VCO and keeping the phase slew of the feedback signal to a minimum, the PLL may be activated and settle to a desired frequency within a relatively short amount of time. By keeping this time so short, the PLL may be placed into and pulled out of a low-power mode and still meet rigid timing requirements of various transmission protocols.Type: GrantFiled: July 13, 2018Date of Patent: July 28, 2020Assignee: QUALCOMM IncorporatedInventors: Terrence Brian Remple, Ilker Deligoz

Patent number: 10356504Abstract: Low latency transmission systems and methods for long distances in SOUNDWIRE systems are disclosed. In an exemplary aspect, a SOUNDWIRE sub-system is coupled to a long cable through a bridge. The bridge converts SOUNDWIRE signals to signals for transmission over the long cable and converts the signals from the long cable to the SOUNDWIRE signals for transmission in the SOUNDWIRE sub-system. Conversion between signal types may include concatenating signals of a similar type into a group that is serially transmitted over the long cable. Concatenation of bit slots in this manner consumes minimal overhead in bus turnaround, thereby reducing latency. In further aspects, the functionality of the bridge may be incorporated into a headset or a mobile terminal.Type: GrantFiled: January 29, 2018Date of Patent: July 16, 2019Assignee: QUALCOMM IncorporatedInventors: Lior Amarilio, Terrence Brian Remple

Patent number: 9990328Abstract: Two super-speed lanes may be enabled on a single USB cable. In an exemplary, non-limiting aspect, the USB cable is a Type-C cable. In further non-limiting aspects, the super-speed lanes may be present even if there is no USB 2.0 lane present on the D+/D? pins of the USB cable. Use of the second super-speed lane increases data throughput. Eliminating the requirement that the D+/D? pins be used for USB 2.0 data allows greater flexibility in the use of the USB connection because audio or video data may be sent over the D+/D? pins instead of USB 2.0 data. Further, the use of the two super-speed lanes allows a single computing element to operate as a host on one lane and a device on a second lane.Type: GrantFiled: December 4, 2015Date of Patent: June 5, 2018Assignee: QUALCOMM IncorporatedInventors: Nir Gerber, Itamar Berman, Yair Shmuel Cassuto, Terrence Brian Remple

Patent number: 9971730Abstract: A link layer to physical layer (PHY) serial interface is disclosed. In one aspect, a system on a chip (SoC) integrated circuit (IC) includes a link layer circuit, and a remote IC includes a Universal Serial Bus (USB) PHY circuit. A bus having four or fewer wires connects the two ICs. A link bridge communicates with the link layer circuit and serializes USB Transceiver Macrocell Interface (UTMI) signaling received from the link layer circuit as high speed (HS) USB messages for transmission to the remote IC. The link bridge also receives HS messages from the USB PHY circuit on the remote IC. The link bridge deserializes the HS messages to extract UTMI signaling and passes the extracted UTMI signaling to the link layer circuit.Type: GrantFiled: June 15, 2015Date of Patent: May 15, 2018Assignee: QUALCOMM IncorporatedInventors: Terrence Brian Remple, Nam Van Dang, Sassan Shahrokhinia

Patent number: 9470644Abstract: Electronic devices are adapted to facilitate detection of a type of USB charger to which an electronic device is connected. According to one example, an electronic device can apply a current source to a data line of a USB plug coupled to a USB port. A determination can be made whether the data line has gone to a LOW state or remained at a HIGH state after a predetermined period of time. If the data line has gone to a LOW state, the USB port may be identified as a downstream port, such as a standard downstream port (SDP) or a charging downstream port (CDP). If the data line has remained at the HIGH state, the USB port may be identified as a dedicated charging port (DCP), no matter if it is compliant or non-compliant with the BC 1.2 spec. Other aspects, embodiments, and features are also included.Type: GrantFiled: November 18, 2013Date of Patent: October 18, 2016Assignee: QUALCOMM IncorporatedInventors: Terrence Brian Remple, Devdutt Patnaik, Jay Yu Jae Choi
