Problems solved by technology

However, the existing connectors are passive physical devices and have no involvement in the noise processing of TTL signals, so the stability and continuity of TTL signal transmission are limited, especially after long-term work, the stability of the connectors will become more and more Poor, not conducive to high-speed and high-quality communication between boards
In addition, in the inter-board transmission link of the TLL signal, due to the default DC isolation design, there are inter-board ground currents and EMI leakage phenomena, which easily cause inter-board interference problems

Embodiment 1

[0038] Such as Figure 1~2 As shown, the high stability active transmission connector provided in this embodiment includes an intermediate wire 1, an SOC conversion control chip 2 and a pin header 3, wherein the end of the intermediate wire 1 passes through the SOC conversion control chip 2 The pin header 3 is connected in communication.

[0039] Such as figure 1 As shown, in the structure of the highly stable active transmission joint, the intermediate wire 1 is used to transmit the converted intermediate transmission signal to the other end joint, or receive the intermediate transmission signal from the other end joint. The SOC conversion control chip 2 is a SOC (System on a Chip, System on a Chip) integrated circuit chip with a built-in encoding / decoding link and a control processing unit, and its size may not exceed 4*4mm. The pin row 3 is used as an on-board plug-in component of a transmission connector, which may be, but not limited to, a single row of pins or a double...

Abstract

The invention relates to the technical field of data transmission and discloses a high-stability active transmission joint which provides a novel active transmission connector by implanting a SOC conversion control chip into an end of a plug, On the one hand, the interconversion between TTL signal and intermediate transmission signal can be realized by using the encoding / decoding link inside the SOC conversion control chip, converting a transmission device using the transmission connection from a passive physical device to an active encoding / decoding structure, On the other hand, the encoder can be controlled to switch to an appropriate transmission encoding model according to the noise sampling results of the physical contacts at the TTL end, so that the input noise can be eliminated by encoding, thereby greatly improving the stability and continuity of the whole active transmission joint and facilitating long-term plug-in use. In addition, by configuring a transmission isolation unitin the encoded link, the end-to-end TTL link can be dc isolated, minimizing board-to-board ground current and EMI leakage.

Description

technical field [0001] The invention belongs to the technical field of data transmission, and in particular relates to a highly stable active transmission joint. Background technique [0002] In current electronic equipment, a connector with pin headers is usually used between circuit boards to realize the transmission of TTL (Transistor-Transistor Logic, logic gate) signals. However, the existing connectors are passive physical devices and have no involvement in the noise processing of TTL signals, so the stability and continuity of TTL signal transmission are limited, especially after long-term work, the stability of the connectors will become more and more Poor, not conducive to high-speed and high-quality communication between boards. In addition, in the inter-board transmission link of the TLL signal, due to the default DC isolation design, there are inter-board ground currents and EMI leakage phenomena, which easily cause inter-board interference problems.
