Embodiment Construction

[0046] Please refer to figure 1 , which shows the device 10a according to the third embodiment of the present invention; the device 10a can be integrated and implemented in a chip, extract the data carried by it from a signal Din, and distinguish each bit in the signal Din (that is, the bit metadata). For example, the signal Din may include a pair of differential interface signals. The device 10 a is provided with a unit bit detector 12 a , a decoder 14 and a buffer 16 . A sampling module 18 , a synchronous detector 20 , a data length calculator 22 a , a bit refresher 24 and a low-pass filter 26 are provided in the unit bit detector 12 a.

[0047] In the unit bit detector 12a, the sampling module 18 is coupled to the signal Din and a sampling clock CLK, and samples the signal Din according to the trigger of the sampling clock CLK to obtain a plurality of sampling values; these sampling values ​​are arranged in sequence in the data Ds. The sampling module 18 is also coupled...

Abstract

The invention discloses a data extracting method and a data extracting device. The data extracting method comprises the steps of: sampling a signal so as to obtain a plurality of sampling values; providing a reference sampling number value when states of the sampling values are changed, and providing a unit bit sampling number value according to the reference sampling number value; and corresponding each sampling value to each bit datum in the signal according to the unit bit sampling number value. According to the data extracting method and the data extracting device, the high cost of external oscillators, such as crystal oscillators, and external connecting pins can be saved.

Description

technical field [0001] The present invention relates to a data extraction method and a related device, and in particular to a method and a related device capable of extracting data bits and / or data clock pulses without locking the data clock pulses. Background technique [0002] The electronic devices exchange interface signals, and the interface signals carry digital data, so that the electronic devices can communicate and exchange information. When a sending-end electronic device wants to transmit digital data to a receiving-end electronic device, the sending-end electronic device will serialize each bit of the digital data in an interface signal according to a certain data clock pulse, and send this interface The signal is transmitted to the receiver. After receiving the signal, the electronic device at the receiving end needs to extract data from the interface signal to retrieve the metadata of each bit in the interface signal, and then interpret the information and inf...
