Abstract

The invention discloses programmable device-based signal conversion equipment, which comprises a communication interface module, a control module, an LVDS image demodulating module, an SERDES image demodulating module, an SERDES image sending module, an RGB converting module, an SERDES image transmitting and packaging module, an LVDS converting module, an MIPI converting module, a TTL interface module and extended interfaces. The signal conversion equipment is designed based on a programmable device and is compatible with LVDS signals, DP signals, MIPI signals, LVDS signals and TTL signals to realize the signal conversion from LVDS signals to DP signals/MIPI signals/LVDS signals/TTL signals. The output signals of the signal conversion equipment can be expanded and applied to signal sources required for multiple tests on modules. Meanwhile, the signal conversion equipment enables the signal cascading function and realizes the cascading function of SERDES signals and the converting function of TTL signals to DP video signals. Therefore, the extensibility of the signal conversion equipment is realized.

Description

technical field [0001] The invention belongs to the technical field of signal processing, and more specifically relates to a signal conversion device based on a programmable device. Background technique [0002] At present, mainstream module testing equipment on the market uses different display chip devices to support module point-screen testing with different display interfaces and resolutions. However, these testing equipment have high unit prices, complex operations, and low reliability. [0003] The module test signal conversion device in the prior art adopts the combination of MCU and FPGA to realize the signal conversion function, or adopts the technical solution combined with ARM and FPGA to realize the signal conversion function; the technical solution combining the two chips is unavoidable on the PCB There are signal interconnections, and the crosstalk between signals will affect the reliability of the signal and reduce the accuracy of the test results; and the tec...
