摘要： A method for detecting the DVI off-line mode and associated DVI receiver are provided. The DVI receiver comprises a plurality of receiving channels, a clock channel, and an off-line mode detector. Each receiving channel receives a video signal and the clock channel receives a clock signal. Each receiving channel comprises a channel decoder for decoding the signals received by the corresponding receiving channel. The off-line mode detector couples with the clock channel and the decoders. The off-line mode detector detects an activity of the clock signal to determine whether to turn on at least one receiving channel for a first predetermined period. The off-line mode detector comprises a mode detector, a clock detector, and a power down controller. The power down controller is coupled to the mode detector and the clock detector. The power down controller enables the mode detector to determine the operation mode of the video signal, and then the power down controller turns off all decoders and channels for a second predetermined period when the operation mode is determined as invalid. Preferably, the second predetermined period is much longer than the first predetermined period.

摘要： In the data recovery circuit of the invention, a first group of sampling clock pulses is used for sampling approximately the central portions of the data bits in an incoming data stream to produce a first sampled data stream, while a second group of sampling clock pulses is used for sampling approximately the transition portions between every two adjacent data bits in the incoming data stream to produce a second sampled data stream. By detecting the resemblance of each bit in the second sampled data stream to the corresponding two adjacent bits in the first sampled data stream, a phase detection and correction circuit determines an early condition or a late condition for the phases of the sampling clocks and produces a signal to correct the phases of the sampling clocks by shifting the phases backwards or forwards. According to the invention, sampling clocks with lower frequencies can be used for sampling, and the phase error can be corrected to obtain the correct data recovery.
