The invention relates to a circuit, in particular to an LVDS (Low Voltage Differential Signal) receiving circuit capable of supporting a DDR (Double Data Rate) data format, and belongs to the technical field of integrated circuits. According to the technical scheme provided by the invention, the LVDS receiving circuit capable of supporting the DDR data format comprises an LVDS interface receiving circuit used for receiving multiple paths of LVDS differential data, and a DDR format conversion circuit connected with the LVDS interface receiving circuit; the LVDS interface receiving circuit can convert each path of received LVDS differential data into a corresponding CMOS (Complementary Metal Oxide Semiconductor) signal; the DDR format conversion circuit can convert each path of CMOS signals which are received by the LVDS interface and are obtained by circuit conversion into two paths of SDR (Single Date Rate) signals. The LVDS receiving circuit is compact in structure, failure protection can be realized, the LVDS receiving circuit can work in a wide input common-mode voltage range and supports to input the data of a DDR format, a data transmission rate is improved, and the LVDS receiving circuit is safe and reliable.
