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.

Abstract: A solar-powered ground plug repelling device, comprises: a casing assembled by a face cover and a bottom housing, a PCBA arranged in the casing, and a ground pipe, wherein a sliding groove assembly is provided on a surface of the bottom housing connected with the ground pipe and comprises two sliding grooves parallel to each other; a sliding rail assembly is provided on an end of the ground pipe connected to the bottom housing and comprises two sliding rails respectively movably connected to the two slide grooves, two electrode elastic sheets connected to the PCBA are provided in the casing, a connecting surface of the electrode elastic sheet protrudes from a perforation in a bottom plate of the bottom housing; and the device comprises two electrode thimbles connected with the sliding rail assembly, and ends of the electrode thimbles are exposed from a surface of the slide rail assembly.
