摘要： The disclosure is a device and a method for Non Return to Zero (NRZ) Clock Data Recovery (CDR) calibration, which includes a CDR unit and a weight calculator unit. The CDR unit receives a compensative signal of an equalization filter to generate an error signal, a sampling clock signal, a transition sampling signal and a data signal. The weight calculator unit receives the error signal, the transition sampling signal and the data signal, and then uses a run length technique to generate weight data. The weight data controls a voltage control oscillator (VCO) which calibrates the phase and the frequency of the sampling clock signal.

摘要： This invention discloses a self-timing method for phase adjustment. An analog signal is digitized at a first and second phase with respect to the symbols comprised in an analog signal in order to obtain first and second quantized samples. Then a first counter out of a first plurality of counters is increased if said first quantized sample has a first digital value to which said first counter is associated. Moreover a second counter out of a second plurality of counters is increased if a second quantized sample has a second digital value to which the second counter is associated. Finally the sampling phase is adjusted based on the values of the counters of the first and second plurality of counters. Moreover a digitizing, self-timing circuit is disclosed.

摘要： A decoder and related method adaptively generate a clock window. A falling edge of a horizontal synchronization signal is detected, and the time difference between an actual frame code and a predefined frame code is determined. The beginning and the end of the clock window are then adaptively determined based on the falling edge and the time difference, such that symbol timing recovery through received clock run-in signals may be performed within the generated clock window.

摘要： A passive phase jitter modulation (PJM) tag is charged with power in a continuous wave (CW) section. When receiving a command from a reader, the passive PJM tag must recognize the command and determine exactly when to begin demodulating the command. Only then can the passive PJM tag demodulate the command. To this end, a synchronization apparatus for accurately demodulating a signal input to a PJM tag includes a plurality of correlators correlating a received phase jitter-modulated signal with a template of an internal matched filter which is in the same form as at least a portion of a modified frequency modulation (MFM) flag.

摘要： A synchronism pattern detecting timing recorder (20) records a synchronism pattern detecting timing at which a synchronism pattern is detected in reception data, a synchronism decider (12) collates the reception data with reference data to decide whether or not the reception data is consistent in phase with the reference data, and a timing generator (22) operates, when the synchronism decider (12) gives a decision for inconsistency in phase, for a match between the synchronism pattern detecting timing recorded in the synchronism pattern detecting timing recorder (20), as a subsequent one, and a timing of a synchronism pattern of the expectation data, and the subsequent synchronism pattern detecting timing in record is used to render the phases consistent, allowing for a rapid synchronization to be obtained, without the need of waiting a detection of synchronism pattern, even with an inconsistency in phase due to a false synchronism pattern.
