Method and system for managing the reception of data frames, scheduled statically and periodically, a frame includes a header provided with an identifier (id) of the frame and an index (index) representing the occurrence of the frame in a hyper-period.

A system includes a plurality of line cards and a timing card. A clock generation circuit on the timing card generates a clock signal which is pulse width modulated according to information to be transmitted. A clock line supplies the pulse width modulated clock signal to the line cards. The timing card sends a first control word to the plurality of line cards over the clock line after sending a beacon. The first control word includes a size field specifying a first length of first data following the first control word. The timing card sends time of day information over the clock line to the line cards following the first control word. The time of day information may be encrypted. A second control word follows the time of day information. One or more additional control words can follow the second control word before the next beacon.

An optical transmitter based on optical time division multiplexing is disclosed, which may solve the issues of complex structure and operation of a multilevel-OTDM-based optical transmitter while using a multilevel signal modulation format and OTDM technology that may increase the transmission rate of an optical transmitter with limited bandwidth.

Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.

A multi-chip module (MCM) includes a first integrated circuit (IC) chip to receive first data. The first IC chip includes a first transfer interface to transmit the first data off the first IC chip. A second IC chip includes an input interface to receive the first data from the first IC chip. The second IC chip includes switching circuitry to selectively forward the first data to one of a first output interface or a second output interface. The first output interface is communicatively coupled to a third IC chip, while the second output interface is configured to output the first data from the MCM.

Some embodiments include apparatuses and methods using a clock generator to generate clock signals, the clock signals being out of phase with each other; a transmitting circuit to provide patterns of data at an output of the transmitting circuit responsive to timing of the clock signals; and calculation and control circuitry to calculate an integral nonlinearity vector that represents offsets of transitions of the patterns from respective target positions, and to generate control information based on the integral nonlinearity vector to adjust phases of the clock signals based on the control information.

It is made possible to favorably perform signal transfer between a plurality of daisy-chain-connected devices. There is a communication line for performing communication between a first electronic device and a second electronic device. A data generating section generates first data to be transmitted to the first electronic device. Then, a data input section inputs the first data to a first position on the communication line. In addition, a first data suppressing section is provided at a second position on the communication line, the second position being closer to the second electronic device than the first position is, and the first data suppressing section prevents the first data from being sent to the second electronic device.
