摘要（英）：

A chip with a receiver test function comprises a signal generation circuit, a jitter injection circuit, a signal hybrid circuit, a receiver and an error code detection circuit. The signal generation circuit is used for generating and outputting a reference signal. The jitter injection circuit is used for generating and outputting an interference signal. The signal hybrid circuit is used for mixing the reference signal and the interference signal and outputting a test signal. The receiver is used for receiving the test signal and outputting the received test signal. The error code detection circuit is used for receiving the reference signal from the signal generation circuit and the test signal from the receiver, comparing and judging whether the test signal includes the same code element information as the reference signal, and further judging whether a receiving capacity of the receiver meets requirements. The invention also relates to a circuit board with the receiver test function.
