摘要： Embodiments of the present invention provide a network device operable to receive a network signal that may include both power and data from a coupled network. This network device includes a network connector and an integrated circuit. The network connector physically couples the network device to the network. An optional protection circuit may provide surge protection or incoming network signals received by the network device through the network connector. An optional switching/rectifying circuit sees the output of the protection circuit and is operable to rectify a power signal when contained within the network signal. The integrated circuit further includes a power feed circuit conductively coupled to the protection circuit and the rectifying circuit. This power feed circuit is operable to separate and pass the received data signal to a network physical layer and separate and pass the received power signal to a power management module. The power management module electrically couples to the integrated circuit but is not necessarily part of the integrated circuit. The power management module is operable to at least partially power the network device for specific circuits within the network device from the received power signal.

摘要： A signal isolator comprises an isolation barrier, a transmitter, a differentiator, and a recovery circuit. The transmitter is coupled to a first side of the isolation barrier and is configured to receive and convert an information signal to a differential signal that encodes information in the information signal in a single transition edge. The differentiator is coupled to a second side that is isolated from the first side of the isolation harrier and differentiates the differential signal. The recovery circuit is coupled to the differentiator and operates to recover an output information signal based on the information in the single transition edge.

摘要： A timing recovery circuit is disclosed that prevents phase error over-compensation. The timing recovery circuit includes a phase scanner for determining when phase error over-compensation has occurred and generating a signal for preventing dual phase compensation in response thereto thereby providing an accurate recovered clock signal. The timing recovery circuit also includes a feed-forward equalizer having a plurality of taps providing coefficients for filtering and adapting the input timing recovery circuit to an input signal. The phase scanner compares the tap coefficients to generate signal for preventing phase over-compensation by the feed-forward equalizer. A phase detector is provided for sampling coefficients from the feed-forward equalizer, error signals and output data and generating a phase signal used to generating the recovered clock signal. The signal for preventing phase over-compensation is mixed with the phase signal to generate the recovered clock signal.

摘要： The present invention provides a method to at least partially power an Ethernet device from a plurality of balanced network power signals received through a network connection. This involves attaching the network device to the network, wherein network signals are received and contain both power signals and/or data signals. These network signals may be passed through surge protection and power-conditioning circuitry wherein the output of these circuits may be provided to a power absorbing circuit. This power absorbing circuit may separate the communication signal and power signal from the network signal. The communication signal may be passed to a network physical layer while the power signal may be passed to a power distribution module. Additionally, because certain embodiments may provide multiple pairs of network power signals to the power absorbing circuit, the current or power associated with each power signal must be sensed and balanced. This may be done with an active control circuit. The balanced power signals may then be supplied from the power absorbing circuit to the network-attached device in order to at least partially power the network-attached device.

摘要： An efficient implementation of a multirate filter with delayed error feedback prevents an instruction processing rate requirement from increasing by performing interpolation and decimation in a LMS filter element at the same time. The multirate filter calculates an ith coefficient value, wherein i is a set of consecutive integers, by obtaining an (i-1)th error value, obtaining an (i-1)th data value, multiplying the (i-1)th error value and the (i-1)th data value to obtain an ith coefficient product, obtaining Mth coefficient value from a coefficient register, wherein M is a predetermined integer, adding the Mth coefficient value to the ith coefficient product to obtain an ith coefficient value calculating an ith data value by multiplying the (i-1)th data value and the Mth coefficient value to produce ith convolution product, and adding an (i-1)th convolution sum to the ith convolution product to produce an ith convolution sum. Obtaining of the Mth coefficient value decimates the convolution product by M and interpolates the error value by M. Obtaining of the (i-1)th data value further includes incrementing a data register by one when new data is not written into the data register.
