Embodiment Construction

[0045] Exemplary embodiments will be described in more detail with reference to the accompanying drawings. However, example embodiments may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, exemplary embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope to those skilled in the art. Like reference numbers refer to like elements throughout the application.

[0046] It will be understood that although the terms first, second etc. may be used herein to describe various elements, these elements should not be limited by these terms. These terms are used to distinguish one element from another. For example, a first element could be termed a second element, and, similarly, a second element could be termed a first element, without departing from the scope of example embodiments. As used herein, the term "and / or" includes any and all combinations of one or m...

Abstract

A data transmission device may include a transmission chip, a plurality of reception chips and / or a pair of transmission lines. The transmission chip may transmit data and the reception chips may receive the data from the transmission chip. One of the plurality of reception chips may provide a corresponding terminal resistance when it receives the data. The transmission lines may be coupled between the transmission chip and the reception chips, and the transmission lines may have a daisy-chain configuration. Therefore, a data transmission device may provide a fixed terminal resistance in impedance matching and increase a transmission speed.

Description

technical field [0001] The invention relates to a data transmission device and a method thereof. Background technique [0002] A data transmission device such as a flat panel display device may use a multi-drop structure in which several chips are simultaneously connected to a common channel to increase data transmission capacity. [0003] FIG. 1 is a block diagram of a conventional data transmission device illustrating a multi-switch structure. [0004] Referring to FIG. 1 , the conventional data transmission device may include a transmission unit 10 , a connector 20 , a plurality of transmission lines 30 , a plurality of receiving units 21 to 28 and a termination unit 60 . The receiving unit 21 can be connected to the transmission line 30 through a via connection point 40 and a stub 50 . The termination unit 60 may include one or more termination resistors Rt and may be connected to the plurality of transmission lines 30 . [0005] Even though the data receiving bandwid...
