A six-category desktop box circuit structure

Abstract

The invention belongs to the field of the electronic technology, and provides a circuit structure of a six-class tabletop box. The circuit structure of the six-class tabletop box comprises a first input line, an RJ45 plug, an RJ 45 socket, RJ45 plug and socket needle pieces, a circuit board connecting end, an IDC routing seat, an IDC routing seat circuit board and a second input line, wherein the IDC routing seat circuit board of an interface circuit structure is divided into two layers and eight routes, and a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a sixth capacitor, a seventh capacitor, an eighth capacitor, a ninth capacitor, a tenth capacitor, an eleventh capacitor and a twelfth capacitor used for balancing signal interference from the eight routes of the RJ45 plug, the RJ 45 socket and the IDC routing seat are formed among the eight routes. The circuit structure of the six-class tabletop box has the advantages that different capacitances are generated among the circuits through the layout of the eight needle pieces or the reasonable wire distribution of the circuit boards, the signal interference from the eight circuits of the RJ45 plug, the RJ 45 socket and the IDC routing seat is balanced through the reasonable capacitance distribution, and therefore the circuit structure of the six-class tabletop box can stably transmit signals under the high frequency of 250MHz.

Description

technical field [0001] The invention belongs to the field of electronic technology, and relates to a desktop box circuit, in particular to a six-category desktop box circuit structure. Background technique [0002] In order to adapt to high-speed network applications, a Category 5 (Category 5, Cat. 5) 1OOMHz cabling system has been developed, and a Cat. The biggest difference from the Category 5 standard is to improve its performance in terms of crosstalk and return loss. For the new generation of full-duplex high-speed network applications, excellent return loss performance is extremely important. Existing If the six types of desktop box circuit in the technology adopt figure 1 , figure 2 as well as image 3 The connection method shown above is set. Although this method can reduce crosstalk and improve return loss to a certain extent, there is a lot of electromagnetic interference, which seriously affects the transmission of information. , still unable to transmit sign...
