摘要
A transmitter-only integrated circuit (IC) chip for performing an external loopback test without an additional receive pin in a chip and an external loopback test method include drivers, mounted on the transmitter-only IC chip, for transmitting data through transmit pads that are installed in correspondence to a plurality of channels; and a loopback test circuit for receiving data as external loopback data through one of the transmit pads set as a receive pad for a test, the data being transmitted through one of the remaining transmit pads, and then comparing the received external loopback data with original transmit data.
