摘要： A multi-chip module (MCM) may include a substrate, and first and second physical-layer (PHY) chips mounted on the substrate. In some implementations, the first PHY chip includes a multiplexer and a PHY circuit. The multiplexer is configured to receive a multiplexed data stream from a media access control (MAC) device, to demultiplex the multiplexed data stream into first and second data streams, to output the first data stream to the PHY circuit, and to output the second data stream to the second PHY chip. In some implementations, the first PHY includes a router and a PHY circuit. The router is configured to receive a plurality of data packets from a MAC device, to route one or more of the data packets having a first address to the PHY circuit, and to route one or more of the data packets having a second address to the second PHY chip.

摘要： Techniques efficiently serialize multiple data streams using quadrature clocks. Serializer employs first, second, third, and fourth clock signals. Serializer receives multiple data streams via registers, with each of four paths comprising a register, buffer, and switch, with registers of first and fourth paths associated with third clock signal, and registers of second and third paths associated with first clock signal, and with switches of first and fourth paths associated with first clock signal, and switches of second and third paths associated with third clock signal. Switches of first and second paths transfer respective data bits to fifth switch via another buffer, wherein fifth switch is associated with a delayed second clock signal of a time delay component (TDC). Switches of third and fourth paths transfer respective data bits to sixth switch via another buffer, wherein sixth switch is associated with a delayed fourth clock signal of TDC.

摘要： A phase synchronized optical master-slave loop comprises at the slave-end a processor (105) configured to include a first timing signal into a bit stream to be transmitted to the master-end, detect a second timing signal from a bit stream received from the master-end, and calculate a phase difference between a regenerated phase signal and a reference phase signal on the basis of a transmission moment of the first timing signal, a first time-stamp indicating a reception moment of the first timing signal at the master-end, a reception moment of the second timing signal, and a second time-stamp indicating a transmission moment of the second timing signal from the master-end. The processor is configured to read the time stamps from the received bit stream that corresponds to a received light signal according to a reception line-code. Thus, conversion of data format is not necessary for the phase synchronization.

摘要： Provided is a data transmission method and device. The method includes: receiving IQ data from an uplink; according to the mapping of the IQ data in a Common Public Radio Interface (CPRI) basic frame, utilizing at least one storage unit to sequence the IQ data; combining a control word with the sequenced IQ data to form CPRI data, and transmitting the CPRI data. The solution utilizes at least one storage unit to sequence the IQ data, and extracts the sequenced data for a CPRI framing operation. This solution is simple in hardware processing and low in realization complexity. The change and upgrade of the transmission bandwidth of multiple modes (single mode or mixed mode) during system upgrade only occur on software layer without affecting the realization of hardware, thus having good flexibility.
