The invention provides a method for being compatible with multiple types of AD acquisition. The method comprises the following steps that (1) an AD clock is processed; Step (2), data synchronization;And step (3): signal synchronization. through a clock synchronization circuit of a plurality of AD signals, a combination method of different AD signals, asynchronous processing logic and the like, the compatibility of a circuit or a chip can be improved, and the cost and complexity of version maintenance are reduced.
