Abstract
A data transmission circuit board, a mobile industry processor interface and a device are provided. The data transmission circuit board includes: a wiring substrate; a plurality of data transmission line pairs on one side of the wiring substrate; and a plurality of transient voltage suppression diodes on the one side of the wiring substrate. Data transmission lines of the data transmission line pairs are coupled to the transient voltage suppression diodes in a one-to-one correspondence, the line width of at least one data transmission line is within a line width threshold range; and the transient voltage suppression diode is configured to discharge when a voltage to ground on the corresponding data transmission line is greater than a discharge voltage threshold, wherein the discharge voltage threshold is not less than a maximum voltage value of the differential signal transmitted on the data transmission line.
