Abstract: Designs of devices having digital phase locked loop (DPLL) circuits that include multiple digital feedback loops to generate high frequency clock signals by a digitally controlled oscillator (DCO). A time-to-digital converter (TDC) module is provided in such a DPLL circuit to receive an input reference clock signal and a first feedback clock signal from a first digital feedback loop and produces a digital TDC output indicative of a first phase error caused by a difference in time between the input reference clock signal and the first feedback clock signal. A second digital feedback loop is provided to generate a second digital feedback signal indicative of a second phase error caused by a difference in frequency between a desired clock signal and a generated clock signal generated by the DCO. The first and second digital feedback loops are coupled to the DCO to generate the high frequency clock signals.

Abstract: There is provided a method for use in a wireless communication to avoid detection of a false modulated signal in a paged device. In one embodiment, a modulated signal is received by the paged device. Then, the modulated signal is identified by the paged device as a preliminary false modulated signal. Thereafter, the gain of at least one paged device amplifier and/or a matching threshold of the paged device is reduced by the paged device to decrease a sensitivity of the paged device to avoid detection of a future false modulated signal. In one embodiment, the wireless communication is a Bluetooth wireless communication and the paged device is a Bluetooth enabled device. An exemplary system for implementing one embodiment of the disclosed method is described.

Abstract: A host device may be enabled to support a plurality of wireless interfaces, wherein some of these interfaces may be utilized to support human interface device (HID) based communication. The host device may be enabled to monitor activity of HID devices based on communications via HID capable wireless interfaces, may predict future use of the HID devices based on the monitoring, and may manage sniff communication that is utilized to track and/or detect activities in the HID devices. The management of the sniff communication may comprise adjusting characteristics of the sniff communication to enable improving throughput of other wireless interfaces available via the host device that may be affected by the sniff communication. The adjustment of the characteristics of sniff communication may comprise adjusting, statically and/or dynamically, length of sniff intervals and/or designating of sniff packets as high priority requests.

Abstract: Techniques for localized dynamic channel allocation help meet the challenges of latency, memory size, and channel time optimization for wireless communication systems. As examples, advanced communication standards, such as the WiGig standard, may support wireless docking station capability and wireless streaming of high definition video content between transmitting and receiving stations, or engage in other very high throughput tasks. The techniques help to deliver the desired user experience in such an environment and support desired performance levels for latency and throughput while controlling memory footprint.
