Programmable device-based signal conversion equipment

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.
