Data processing device and data processing method

Abstract

The present technology relates to a data processing device and a data processing method capable of outputting appropriate multi-level signals at desired multiple levels in data transmission based on multi-level signals with a simple configuration. A first to M-th drivers to which control signals are input and that output voltages corresponding to the control signals are provided for a transmission line through which a multi-level signal representing transmission data with voltage levels as many as the number of states N is transmitted, in which an integer larger than or equal to 3 and different from a power of 2 is set as the number of states N and a power of a smallest integer that is a power of 2 larger than or equal to N is set as a control value M. The first to M-th drivers include first to M-th output resistors, respectively, and in a case where any integer larger than or equal to 1 and smaller than or equal to M is denoted by m, a resistance value of an m-th output resistor in which m is smaller than or equal to M−1 is a value obtained by dividing a predetermined resistance value by 2 raised to a power of (m−1), and a resistance value of an M-th output resistor in which m is M is a value obtained by dividing the predetermined resistance value by a value obtained by subtracting 2 raised to a power of (M−1) from N.
