Control method for controlling ASIC by optical module

Abstract

The invention discloses a control method for controlling an ASIC by an optical module. The control method comprises the following steps that: 1, an input variable is converted into a digital matrix byan ASIC chip; and 2, the ASIC chip inquires the digital relation matrix of the transfer function through an addressing table look-up method to obtain the output control quantity of the input variable, and outputs the output control quantity to the controlled optical module chip, wherein the conversion of the digital relation matrix of the transfer function is completed in an upper computer, and the digital relation matrix is received and stored through an I2C bus when the ASIC chip is initialized. According to the control method, variable complex transfer function control of any input quantity and output quantity can be conveniently realized, and effective control of a driving chip in the optical module can be realized. According to the invention, the design and development of the anti-radiation optical module product in the space navigation environment can be realized.

Description

technical field [0001] The invention belongs to the technical field of anti-radiation data communication, and in particular relates to a control method for an optical module to control an ASIC. Background technique [0002] With the development of optical communication technology and the increasing demand for communication bandwidth for data exchange of customer payload systems, more and more customers use optical transceiver module products in aerospace systems, and spacecraft work in complex space radiation environments. There are high requirements on the radiation resistance of optical module products. [0003] Control chips are necessary devices in the design of high-speed optical modules. At present, the existing radiation-resistant general-purpose controllers such as single-chip microcomputers or FPGAs can control the functions of aerospace optical modules, but they still cannot meet the requirements of practical applications. [0004] The control chips used in optica...
