摘要： Continuously interleaved codewords are used in a communication system to provide error correction capability. In general, each codeword shares symbols with both preceding and subsequent codewords, when the codewords are arranged in an order, such that correction of symbols in any one codeword also corrects symbols in another codeword and correction of symbols in any codeword may allow, considering possible corrections of intermediate codewords, for further correction of any codeword in the order of codewords. In one embodiment received information may be arranged in subframes, with each subframe including terminal symbols of a plurality of codewords, each of the plurality of codewords including symbols in multiple subframes.

摘要： Data receivers often include equalizers for operating on received signals. The equalizers often have a plurality of taps, with signals from each tap weighted based on tap settings or values. The tap settings may be set based on bit error rates of data output from the equalizer. In some embodiments data output from the equalizer is split into two signals, and the two signals are processed to indicate a data eye of the data output from the equalizer. Preferred tap settings may be determined by setting tap settings to different values and using tap settings expected to maximize the data eye. This may be performed separately for different bit settings in an attempt to reduce effects of inter-signal interference.
摘要翻译：数据接收器通常包括用于对接收信号进行操作的均衡器。均衡器通常具有多个抽头，每个抽头的信号基于抽头设置或值加权。抽头设置可以基于从均衡器输出的数据的误码率来设置。在一些实施例中，从均衡器输出的数据被分成两个信号，并且处理这两个信号以指示从均衡器输出的数据的数据眼睛。可以通过将tap设置设置为不同的值并使用预期的tap设置来最大化数据眼睛来确定优选的tap设置。为了减少信号间干扰的影响，可以针对不同的位设置分别执行这一点。

摘要： A clock recovery unit is used to recover a clock signal from a transmitted data signal. The clock recovery unit includes a phase locked loop (PLL) circuit and a frequency detection circuit. The frequency detection circuit includes a digital phase tracking circuit (DPTC), which uses a rotational phase shifter to shift phase of a variable clock signal from a voltage controlled oscillator in the PLL circuit, in discrete amounts from 0 to 360 degrees, depending on a digital input code provided by a digital accumulator, which receives up or down count signals from a phase comparator. The shifted variable clock signal is provided to a phase/frequency detector, which provides an output to a glitch suppressor to suppress small phase differences prior to providing the output to the PLL circuit. When the frequency difference between the variable clock signal and the reference clock signal is large, the phase/frequency detector drives the frequency in the correct direction. When the frequency difference is small, the DPTC keeps the phase of the shifted variable clock signal aligned to the phase of the reference clock signal.
