Product Introduction
The chip is a special chip for fiber optic gyro control, which has the characteristics of high integration, small size, low power consumption and strong performance.The main chip devices required for fiber optic gyro control are integrated, which can meet the use of fiber optic gyro with an accuracy of less than 0.5%, which can save about 70% of the volume of the circuit, and can effectively reduce the size of the gyro. At the same time, because the consistency of the chip is better than that of the separation device, it can effectively shorten the R&D cycle of the customer's fiber optic gyro.
Chip composition
The chip mainly includes programmable logic and memory units (FPGA and FLASH), digital-to-analog conversion (DAC), analog-to-digital conversion (ADC), driver (Diver), and communication unit (422).
