A high-precision clock chip compensation production system and method

Abstract

The invention provides a high-precision clock chip compensation production system and method. The system includes a PC and a main control software module, a first-level main control unit, a second-level main control unit, a third-level main control unit assembly module, and a frequency measurement unit. Collection module, reference clock source module, chip DUT backplane module, thermostat module; three-level main control unit collection module contains several three-level main control units; frequency measurement unit collection module contains several frequency measurement units; chip DUT bottom board module Several chip DUT devices are arranged; the chip DUT bottom plate module is arranged in the temperature box. The production system of this scheme has low cost, high precision, good scalability, and significantly improved production efficiency.

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...

Problems solved by technology

When processing the production data of several clock chips, the time consumed is still within an acceptable range; but when processing the production data of tens of thousands of clock chips, this manual method is seriously inefficient and takes a lot of time
