The latest 48Gbps HDMI connection cable will be available soon

The first batch of HDMI 2.1 48G branded cables was announced at the end of 2018, but they have not been formally certified by the HDMI Forum. One of the reasons is that the HDMI 2.1 certification plan is not yet ready. Now the certification of these products is also coming, marked as Ultra High Speed HDMI (Ultra High Speed HDMI). In addition, TV manufacturers are preparing the first batch of ultra-high-definition TVs using HDMI 2.1.

Since the HDMI 2.1 48G cable and the signal source and receiver are physically different from the existing HDMI 1.4/2.0 cables, product manufacturers must adopt new manufacturing methods, and the HDMI Forum must introduce a new certification program, which includes A compliance test to ensure that it works properly at high data rates and supports all functions.

The HDMI Forum admits that cable manufacturers usually have enough experience to build HDMI 2.1 48G products. However, since the HDMI 2.1 48G certification program has not been completed, it is not recommended that they sell products marked with ultra-high-speed HDMI cables.

The HDMI 2.1 48G cable uses 4 data channels, each of which runs at a speed of 12 Gbps, with a total bandwidth of 48 Gbps, which is higher than the current 18 Gbps, while retaining backward compatibility with existing equipment. The additional bandwidth provided by HDMI 2.1 enables it to support new Ultra HD resolutions and refresh rates, including 4Kp/120Hz, 8Kp/100 or 120Hz, 10Kp/100 or 120Hz, and supports upcoming color spaces such as BT.2020( Rec. 2020), 10/12/16 bit color depth. The HDMI Forum plans to launch its UHS HDMI interconnect certification program in the next few months. In the future, “official” HDMI 48G copper and optical cables will be available

Basic knowledge of D-Sub connector for D-type connector

D-type connectors have been widely used for many years. They were originally developed by Cannon in 1952 and are now part of CanT. The D-type connector has been used as a multi-way connector in many applications, but it is probably the most widely known connector for RS-232 serial links. In fact, D-type connectors have been used for serial links on most computers for many years, and various types of D-type connectors can still be found on most computers today.

The D-type connector was originally called a subminiature connector, and the connector is now commonly referred to as a D subminiature connector. Although these connectors were small when they were first introduced, after so many years of development in the connector industry, many sophisticated connector products have been developed and designed in the world, so D-type connectors are no longer considered to be truly ultra-small Connector.

D-type connectors usually consist of two and sometimes more parallel connection rows. The connector has a D-format metal shell, which not only provides mechanical strength for the connector, but also provides some limited screening. The metal shell of the plug and the socket contacts to provide screening. In addition, panel mount connectors are usually fixed to the panel using nuts with additional threads that allow the mating connector to be fixed to it to prevent it from loosening.

In addition, the free connector can have a back shell that can provide shielding, and can be connected to a cable screen. Or if it is plastic, they can provide protection and also provide strain relief on the cable. As expected, the pin-containing connector is a male D-type connector, while the socket pin-containing connector is a female connector. The original D-type connector has two rows of pins, and the total number of pins is an odd number, which causes the connector to have one pin in another row, resulting in an e D shape, which also prevents the mating mechanism of the connector The direction is incorrect.

Function and characteristic of aviation connector socket

The effectiveness of the aviation connector socket:

The key functions are also reflected in the connection of various electronic components. The working frequency of the aviation plug is specified below 12 volts. The aviation plug can maintain continuous working AC power because of its layout advantages, and the AC power through the process is not large.

Aviation Connector Socket Application Frequently Asked Questions:

1. Do not disassemble the aviation connector socket under the condition of induction power, otherwise it will cause risk to the flame, etc., or cause poor characteristics;

2. Condensed water or wetted by water may cause poor grounding between the integrated op amps. If condensed water will be generated or wetted by water, use a moderate anti-drip countermeasure;

3. When applying, do not apply the AC power of the rated current for several integrated operational amplifiers;

4. When applying the air socket row, if the cable line installed on the connector, the resonance of the color printed wiring board, or the rotation structure of the facility and the posture of the movable part, the connector insertion portion (joining portion) is applied from the beginning to the end. Will cause the drag of the touch to be damaged and cause looseness.

Aviation connector socket

The characteristics of the aviation connector socket:

1. Vibration and shock resistance are key features of aerospace connector sockets. They are essential in unique application environments such as civil aviation and aerospace, rail and road freight. This is to test the robustness and electrical construction of aviation plugs and connectors. Touch key indicators of credibility;

2. Moisture-resistant aviation plugs, connectors: the invasion of moisture will damage the dielectric strength of the software connection, and rust alloy parts;

3. Temperature resistance.
