PURPOSE: A board using a universal interface is provided to use the interface universally by forming a module with a termination resistor, by selectively inserting it into a slot, and by selectively connecting to the termination resistor. CONSTITUTION: A bus(11) transfers data. A universal chipset(12) changes the setting of a memory driving mode according to a used logic by connecting to one end of the bus(11). A plurality of memory slots(13) accept a memory module(14) by connecting to another end of the bus(11). A plurality of termination slots(15) are connected to each end of the bus(11), accept the termination modules(16) applying a termination voltage. The termination modules(16) include the termination resistor and a circuit applying the terminal voltage.
Abstract:
PURPOSE: A system board is provided to reduce length differences or load differences of signal lines from a control circuit to each slot so that it can enhance a signal transmission time and a signal transmission feature. CONSTITUTION: The device comprises slots(S1, S2, S3, S4). The length among the slots(S1, S2, S3, S4) is L. Main signal lines(SL) are installed below the slots(S1, S2, S3, S4), and sub signal lines(s15, s16, s17, s18) branches off from branch points(e, f) of the main signal lines(SL) and connects to the slots(S1, S2, S3, S4). The lengths of the sub signal lines(s15, s16) between the branch point(e) and the slots(S1, S2) are the same, and also those of the sub signal lines(s17, s18) between the branch point(f) and the slots(S3, S4) being the same. Though the lengths of the signal lines from the main signal lines(SL) to the branch point(e) are different from those of the signal lines from the main signal lines(SL) to the branch point(f), those length differences of the signal lines are largely reduced rather than a conventional system board so that the signal transmission speeds or characteristics of the slots(S1, S2, S3, S4) are similar and enhanced.
Abstract:
The present invention is applicable to the field of communications technologies, and provides an orthogonal interconnection system and a communications device. The perpendicular and orthogonal interconnection system includes a first board group, a second board group orthogonal to the first board group, and a center backplane arranged between the first board group and the second board group, where the first board group includes a plurality of first boards parallel to each other, and the second board group includes a plurality of second boards parallel to each other; a plurality of right angle male connectors is arranged on each of the first boards, a plurality of right angle female connectors is arranged on each of the second boards, and the right angle male connectors and the right angle female connectors directly cooperate and are connected in one-to-one correspondence. In the present invention, the right angle male connectors and the right angle female connectors directly cooperate and are connected. When the perpendicular and orthogonal interconnection system is upgraded, only the board that permanently has the right angle male connectors and the right angle female connectors needs to be replaced, which is rather simple and shortens a signal link. Based on the foregoing advantages, the perpendicular and orthogonal interconnection system is applicable to various communications devices; therefore, its upgrade is convenient, signal quality is improved, heat dissipation is ideal, and material costs are saved.

Abstract:
An objective of the present invention is to provide a three-dimensional backplane to solve the problem that the number of layers of a printed circuit board for producing a backplane increases linearly along with the number of connectors. The three-dimensional backplane includes: a first group of connectors (S1-S6), a second group of connectors (L1-L8), a first group of printed circuit boards (VB1, VB2), and a second group of printed circuit boards (LB1, LB2). The first group of connectors (S1-S6) and the second group of connectors (L1-L8) are disposed on the first group of printed circuit boards (VB1, VB2) and the second group of printed circuit boards (LB1, LB2) respectively. Any printed circuit board in the first group of printed circuit boards (VB1, VB2) is connected to any printed circuit board in the second group of printed circuit boards (LB1, LB2). Any connector in the second group of connectors (L1-L8) is connected to any connector in the first group of connectors (S1-S6). With the foregoing solution, the number of wires on each printed circuit board is reduced, so that the number of layers of a printed circuit board for producing a backplane is reduced.
