Method and system for realizing isolating low-frequency clock signal transmission among split modules

The invention discloses a method and a system for realizing isolating low-frequency clock signal transmission among split modules, wherein a transmitting terminal obtains low-frequency clock signal and high-frequency clock signal by carrying out frequency division for different times to a master system clock of the system, the low-frequency clock signal is encoded by the high-frequency clock signal and then a high frequency circuit clock is generated, and transmitting and receiving are carried out through an isolating transformer; a receiving terminal utilizes the received high frequency circuit clock to generate synchronous clock and performs delay to the high frequency circuit clock, then decoding is carried out to obtain a low-frequency clock signal with fixed delay; the transmitting terminal and the receiving terminal are both split modules. Correspondingly, the system for realizing isolating low-frequency signal transmission among split modules comprises a transmitting terminal and a receiving terminal,
