The utility model discloses a multipath time pulse output circuit and time frequency equipment, and belongs to the technical field of time unification. The multi-path time pulse output circuit comprises a time pulse generation circuit, an FPGA, a TDC measurement module and a multi-path level conversion circuit. The TDC measurement module comprises a plurality of time-to-digital converters. The output end of the time pulse generation circuit is connected with the initial pulse signal input end of the FPGA, the input end of each level conversion circuit is connected with one shunt time pulse signal output end of the FPGA, and the output end of each level conversion circuit is connected with the to-be-tested signal end of one time-to-digital converter. The reference signal end of the time-to-digital converter is connected with the initial time pulse signal output end of the FPGA, and the output end of the time-to-digital converter is connected with the feedback end of the FPGA. According to the utility model, a
