The invention provides a high-speed interface data sampling circuit and a chip. A phase-locked loop of the high-speed interface data sampling circuit outputs a first clock signal and a second clock signal multiplied by the first clock signal based on a received reference clock signal; the logic processing module carries out multi-stage trigger sampling on the first clock signal according to the second clock signal to obtain a target clock signal, and carries out multi-stage trigger sampling on the received data signal based on the target clock signal, so that the target clock signal is sampled at a specified position of the data signal; the problem of error codes caused by overlarge phase difference between a clock signal and a data signal can be effectively avoided, so that a better sampling effect and a lower error rate can be obtained during high-speed data transmission; meanwhile, the sampling clock and the control clock for parallel-serial conversion can be cooperatively adjusted in phase, so that time sequence deviation in a sampling path and an output path is compensated, and stable and reliable parallel data sampling and serial output of the high-speed interface can still be realized in different rate modes.
