Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to the field of testing, compensation and production of real-time clock chips, and in particular to a high-precision clock chip compensation production system and method. Background technique [0002] In various applications, clock timing is a common function. In most cases, a chip that provides a clock is used, and the standard output frequency is 32.768kHz. It is used in the following occasions, such as consumer electronics, industrial communication, meter grid, base station, counting and timing, etc., and the application environment is relatively harsh. However, the output frequency of the clock chip is generally not absolutely accurate, it always fluctuates around the standard 32.768kHz, and it is related to the change of temperature. At a slightly lower or higher temperature, the output frequency of the clock chip drifts seriously, and the consistency is poor, which makes it...
