Abstract: A communication system may include a number of communication channels operating in accordance with one or more communication standards. The channels may generate data clocks from one or more master clock signals. The phase of the data clocks may be aligned using phase detectors for determining respective phase relationships and using phase interpolators for adjusting respective clock phases. The communication system may include communication channels that operate at different data clock frequencies. These systems may divide their respective data clocks in order to achieve a common clock frequency for use in their phase alignment. The phase detectors and associated circuitry may be disabled to save power when not in use.

Abstract: A communication device is configured adaptively to process a receive signal based on noise that may have adversely affected the signal during transition via communication channel. The device may be configured to identify those portions of the signal of the signal that are noise-affected (e.g., noise-affected sub-carriers of an orthogonal frequency division multiplexing (OFDM) signal), or the device may receive information that identifies those portions of the signal that are noise-affected from one or more other devices. The device may be configured to perform the modulation processing of the received signal to generate log-likelihood ratios (LLRs) for use in decoding the signal. Those LLRs associated with noise-affected portions of the signal are handled differently than LLRs associated with portions of the signal that are not noise-affected. The LLRs may be scaled based on signal to noise ratio(s) (SNR(s)) associated with the signal (e.g., based on background noise, burst noise, etc.).

Abstract: Systems and methods are provided that allow a secure processing system (SPS) to be implemented as a hard macro, thereby isolating the SPS from a peripheral processing system (PPS). The SPS and the PPS, combination, may form a secure element that can be used in conjunction with a host device and a connectivity device to allow the host device to engage in secure transactions, such as mobile payment over a near field communications (NFC) connection. As a result of the SPS being implemented as a hard macro isolated from the PPS, the SPS may be certified once, and re-used in other host devices without necessitating re-certification.

Abstract: A short reach communication system includes a plurality of communication SERDES that communicate data over a short reach channel medium such as a backplane connection (e.g., PCB trace) between, for example, chips located on a common PCB. A multi-level modulated data signal is generated to transmit/receive data over the short reach channel medium. Multi-level modulated data signals, such as four-level PAM, reduce the data signal rate therefore reducing insertion loss, power, complexity of the circuits and required chip real estate.

Abstract: Embodiments provide methods and systems for enabling opportunistic wakeup of a device from a sleep mode. Specifically, embodiments recognize that often incoming packets into a module in a low power mode are not time-critical and can be deferred for processing by the module after a scheduled wakeup time of the module. As such, embodiments provide methods and systems for identifying an incoming packet into a module and determining whether or not to cause the module to exit the low power mode based on characteristics of the incoming packet. Embodiments may be applied to a modem in a wired or wireless device but are not limited as such, and extend to any device which may benefit from the opportunistic wakeup embodiments described herein.

Abstract: Aspects of a method and system for symmetric transmit and receive latencies in an energy efficient PHY are provided. In this regard, a delay introduced by a PHY of a network device for outbound traffic and a delay introduced by the PHY for inbound traffic may be controlled such that a transmit delay of the network device is equal, within a tolerance, to a receive latency of the network device. The delays may be controlled based on whether one or more energy efficiency features are enabled in the PHY. The delay introduced by the PHY for outbound traffic may be controlled based on an amount of buffered inbound traffic. The delay introduced by the PHY for inbound traffic may be controlled based on an amount of buffered outbound traffic. The delays may be controlled such that said receive latency and the transmit latency are approximately constant regardless of a mode of operation of the network device.

Abstract: A circuit for baseband harmonic rejection includes multiple transconductance cells coupled to one another at outputs of the transconductance cells and configured to receive down-converted signals that vary from one another to produce a weighted current signal proportional to a voltage corresponding to a respective down-converted signal.

Abstract: A method, apparatus and computer program product are provided for enhancing data exchange between an access point (AP) and station (STA) in a wireless network when the exchange must be interrupted for the AP to perform other services while data remains buffered for later exchange. AP downlinks an indicator that more data remains for exchange together with a request for the STA to enter sleep mode for a duration scheduled by the AP. Sleep duration may be sent in the medium access control (MAC) header of a data frame, with the indicator of more data and the indicator of the sleep mode request being contained in the frame control (FC) segment of the MAC header. The STA may uplink an acknowledgement (ACK) of the sleep mode. Alternatively, the AP may downlink an ACK of the STA's indication of more data confirmation together with sleep mode indication and duration.
