| 20100202498 | Compensating Transmission line to Reduce Sensitivity of Performance due to Channel Length Variation - Described embodiments provide a method and system for signal compensation in a SERDES communication system that includes monitoring the quality of a data signal after passing through a transmission channel. The quality of the data signal is monitored with at least one of a BER calculation algorithm and a received eye quality monitoring algorithm. Variations in channel length of the transmission channel are compensated for by i) adjusting a length of transmission line delay of the data signal from the transmission channel, ii) comparing the data signal quality with a threshold for the adjusted data signal; and iii) repeating i) and ii) until the data signal quality meets the threshold. | 08-12-2010 |
| 20110274154 | Compensated Phase Detector for Generating One or More Clock Signals Using DFE Detected Data in a Receiver - A method and apparatus generating one or more clock signals in a receiver employing decision-feedback equalization (DFE). A received signal is sampled by a data clock and a transition clock, generating a data sample signal and a transition sample signal, respectively. A DFE correction is performed DFE circuitry on the data sample signal to generate DFE detected data bits. The transition sample signal is sliced using a weighted threshold value to generate corrected transition data. One or more phase updates of the data clock and the transition clocks are in response to the DFE detected data bits and the corrected transition data. The weighted threshold is calculated from at least one prior-received DFE detected data bit. In one embodiment, the DFE correction may also be dependent on an effective delay (λ) of the DFE circuit in relation to the received signal baud-period, T. | 11-10-2011 |

| 20080291832 | Method For Per-Port Flow Control Of Packets Aggregated From Multiple Logical Ports Over A Transport Link - A method is disclosed for controlling the flow of packets aggregated from multiple logical ports over a transport link. A directed flow control indicator is provided to the transmitting end station that causes a detected congestion condition. The directed flow control indicator causes the transmitting end station to suspend the transmission of further packets. The linear expansion header of the Generic Framing Procedure (GFP) linear mapping scheme is extended to include the flow control indicator, such as a bit that is set to a predefined binary value to indicate a potential overload condition. A directed flow control indication can be provided in one or more packets that are sent to the transmitting end station over the transport network without increasing the network overhead. If packets are not being sent to the appropriate transmitting end station, a packet generator can generate one or more packets with the flow control indicator to inform the appropriate transmitting end station of the congestion condition. | 11-27-2008 |
| 20080317109 | CHARACTERIZING NON-COMPENSABLE JITTER IN AN ELECTRONIC SIGNAL - One embodiment of the present invention processes a signal of interest through an optional reference channel, combines the resulting signal with white noise, and then processes the noisy signal through a reference receiver. Two metrics are calculated from the results of that processing: Non-Compensable Data-Dependent Jitter (NC-DDJ) and Enhanced Transmitter and Waveform Dispersion Penalty (Enhanced TWDP). Within the reference receiver, a variable delay module sweeps the eye opening defined by the noise-free samples of the signal of interest and determines the transition points (i.e., edges) of the eye opening. Those transition points are compared to the Unit Interval to yield NC-DDJ. Further, the signal-to-noise ratio (SNR) of the noisy samples of the signal of interest is compared to the SNR of an ideal receiver (i.e., matched filter) driven by an ideal transmitter via an ideal channel with additive white Gaussian noise n(t) to yield Enhanced TWDP. | 12-25-2008 |
| 20090168940 | Methods and Apparatus for Improved Jitter Tolerance in an SFP Limit Amplified Signal - Methods and apparatus are provided for improving the jitter tolerance in an SFP limit amplified signal. Jitter tolerance is improved in a communications receiver by applying a received signal to an SFP limiting amplifier; and applying an output of the SFP limiting amplifier to a low pass filter to improve the jitter tolerance. The low pass filter optionally applies a programmable amount of attenuation to high frequency components of the output. The low pass filter slew rate controls (i.e., rotates) a data eye representation of the received signal to increase the data eye representation along a time axis. The noise margin of the received signal can optionally be improved by applying an output of the low pass filter to an all pass filter. A slew rate controller can evaluate the data eye statistics to determine a setting for the low pass filter. | 07-02-2009 |
| 20100329326 | METHODS AND APPARATUS FOR DECISION-FEEDBACK EQUALIZATION WITH OVERSAMPLED PHASE DETECTOR - Methods and apparatus are provided for decision-feedback equalization with an oversampled phase detector. A method is provided for detecting data in a receiver employing decision-feedback equalization. A received signal is sampled using a data clock and a transition clock to generate a data sample signal and a transition sample signal. A DFE correction is obtained for each of the data sample and transition sample signals to generate DFE detected data and DFE transition data. One or more coefficients used for the DFE correction for the transition sample signals are adapted using the DFE transition data. | 12-30-2010 |
