What are the types of HDMI interface connectors?

The most common HDMI interface connectors in life are Type A connectors and Type B connectors, and their initial standards are the same. In fact, the types of HDMI interface connectors are mainly divided into 5 types, which can be divided into: A type, B type, C type, D type, and E type. These different types of interface connectors are used in different applications to satisfy users Specific needs. The following is a summary of the knowledge of 5 different types of HDMI interface connectors by connector manufacturers.

Different HDMI interface connector types remain unchanged after launch. This allows backward compatibility to be maintained throughout the life cycle of the standard. With the exception of dual-link B-type connectors, they all have 19 pins, keeping the standard the same across all connector types.

1. HDMIA type interface connector

The HDMIA type interface connector was introduced using the original standard and has been the backbone of the HDMI standard since then. The external size of the plug or male connector is 13.9mm × 4.45mm, and the internal size of the socket or female connector is 14mm × 4.55mm. With 19 pins, the bandwidth can carry all SDTV, EDTV, HDTV, UHD and 4K modes. This connector type is electrically compatible with single-link DVI-D.

2. HDMIB type interface connector

The HDMIB-type interface connector was also launched in 2002 as the original standard, designed to carry dual-link DVD-I video. The connector has never been used in the product because with the introduction of HDMI 1.3, the speed of a single link exceeds that of the old dual link. Since the connector is larger than the single-link standard style, there is no reason to use it. But it remains within the specifications. This type of HDMI connector measures 21.2mm x 4.45mm and has 29 pins with 6 differential pairs instead of 3.

3. HDMIC type interface connector

C-type HDMI interface connector is a mini HDMI connector, smaller than the A-type connector, the size is 10.42mm × 2.42mm, but still retain the 19-pin configuration. It was introduced in HDMI 1.3 version. Because the connector configuration is different, all positive signals of the differential pair are exchanged with the corresponding shields. DDC / CEC ground is assigned to pin 13 instead of pin 17, and CEC is assigned to pin 14 instead of pin 13. Pin 17 instead of pin 14.

4. HDMID type interface connector

The size of the HDMITypeD interface connector is very similar to the micro-USB connector, so the D type is usually called micro HDMI. The measured value is only 6.4mm × 2.8mm. In this outline, micro-HDMI reserves 19 pins of other connectors, but the pin assignments are different. This connector was introduced with HDMI version 1.4.

5. HDMIE type interface connector

E-type HDMI interface connector is suitable for automotive applications. This connector was introduced with HDMI version 1.4. To prevent the E-type HDMI interface connector from loosening, it contains a locking tab and a housing to help prevent dust and moisture from entering.

Various types of HDMI interface connectors ensure that the HDMI standard can be successfully used in many different fields, and they can meet the requirements of users using many different applications of HDMI.
