EPT High Speed Connector (EMC Connector) Function and Product Introduction

Definition of high-speed communication: High-speed communication works at higher MHz and GHz frequencies. High-speed communication methods: 1. Traditional analog signals: Analog signals are continuous and linear on the time axis. 2. Digital signal: Digital signal jumps in the form of 0 and 1 on the time axis, T is the signal period, and 1/T is the rate of how many G we usually understand. Current commonly used high-speed communication protocol: PCIe Gen 3, 4... 5, USB3.1 Gen2, HDMI, 10G network, etc. The demand for high-speed communication mainly comes from 4K video, IoT/IIoT, Autopilot, etc. For high-speed communication channels, the connector is the bottleneck that limits the communication rate, so the high-speed performance of the connector is particularly important for the whole communication system.

1. Definition of high-speed communication:

High-speed communication works at higher MHz and GHz frequencies. The common frequencies and wavelengths in our lives are as follows:

High-speed communication mode: 1. Traditional analog signal:

The analog signal is continuously linear on the time axis. 2. Digital signal:

Digital signals jump in the form of 0 and 1 on the time axis, T is the signal period, and 1/T is the rate of how many G we usually understand. The above is just a model of a digital model. The actual digital signal is like this:

It is the jump time from 0 to 1 and from 1 to 0, and it is also the bottleneck that limits the communication rate. Development of high-speed communication protocols;

Current common high-speed communication protocols: PCIe Gen 3, 4... 5, USB3.1 Gen2, HDMI, 10G network, etc. The demand for high-speed communication mainly comes from 4K video, IoT/IIoT, autonomous driving, etc. For high-speed communication channels, the connector is the bottleneck that limits the communication rate, so the high-speed performance of the connector is particularly important for the whole communication system.

The main factors that affect the high-speed performance of the connector are the design of the pin shape, the choice of high-conductivity metal materials, the insulation resistance of the shell, etc., and of course the special design of the backplane connector.

When selecting high-speed communication components such as connectors, the following factors are mainly considered: what standards or specifications does the design of the entire Application follow; Number of I/O; Design of Power I/O and Signal I/O; Transmission rate/frequency; Whether shielding is required; The impedance of the system circuit; The transition time of the digital signal; Input loss; PCB connection technology; Is there an S-parameter.

2. Concerns of various industries of high-speed communication:

Requirements for high-speed connectors by point of concern:

About EMC: How can we ensure the stability of high-speed signal transmission? We call it EMC (Electromagnetic Compatibility) Electromagnetic Compatibility.

In the signal transmission link, the connector is both a signal receiving pool (sink) and a signal transmitting pool (source).

Here's a simple EMC model:

Through special design and the addition of shielding functions, we have greatly reduced interference and interference during the transmission process, improved transmission stability while reducing the distance requirements between components, and improved the compactness of the entire design (the left is an unshielded connector, the right is a shielded connector):

ept's EMC high-speed connector products include:

In addition to providing stable signal transmission, the above connectors can achieve higher transmission speeds of 28Gbps, 8Gbps/16Gbps, and 16Gbps respectively.
