Abstract: This application provides a drive and a data transmission method, to implement low-latency transmission. The drive includes a CDR circuit, an elastic buffer, a receiver circuit, and a transmitter circuit. The CDR circuit is configured to recover a receive clock from a received signal. The receiver circuit is configured to recover sent data from the received signal by using the receive clock. The elastic buffer is configured to move the sent data in by using the receive clock and move the data out by using the receive clock. The transmitter circuit is configured to send the sent data from the elastic buffer by using the receive clock.
