Abstract:
A data recovery system and method is disclosed, which comprises an oversampler, a phase detection circuit, a data pick circuit, a data overlap/skip detection circuit and a data correction circuit. The oversampler oversamples an input signal and thus generates oversampled signals. The phase detection circuit receives for detecting transitions of the oversampled signals and outputting a phase signal. The data pick circuit receives the phase signal, accordingly groups the oversampled signals into n groups and picks one group as an output data. The data overlap/skip detection circuit determines if data is overlapped or skipped according to the phase signal and the last phase signal. The data correction circuit corrects data when data is overlapped or skipped and outputs an accurate output data.
Abstract:
A controller and a method of updating parameters on the same. The controller includes an embedded non-volatile memory, a programming circuit, an embedded SRAM, a MCU (Micro Computer Unit), and a memory controller. The embedded non-volatile memory has a program code block for storing program codes to be executed by the MCU, and a data block for storing the parameters. The MCU writes the parameters into the data block of the flash memory through the memory controller, or reads data in the data block of the non-volatile memory through the memory controller. Because the controller does not need to employ an external EEPROM, the cost can be reduced and the speed for accessing the parameters can be increased.
Abstract:
A phase frequency detector used in a phase locked loop includes a phase error detecting unit for outputting phase error signals according to a phase error between a first input signal and a second input signal, and a reset unit coupled to the phase error detecting unit. The reset unit outputs reset signals according to the first and second input signals so as to reset the phase error detecting unit without delay time. Thus, it is possible to make the output timing of the phase error signal in a more precisely linear proportion to the phase error value and to enhance the sensitivity of the phase locked loop.
