Digital and Analog Video Connector Guide

Digital and Analog Video Connectors

DVI (Digital Visual Interface) – Sends digital information from computer to LCD Display.

TMDS (Transmission Minimized Differential Signaling) – Transmits large amounts of digital data from the source to the display resulting in high-quality images.

HDMI (High Definition Multimedia Interface)

Gender: Male

Carries same video information as DVI but adds the capacity for digital audio and control signals as well. HDMI uses a 19-pin connector.

HDMI Mini

Gender: Male

Same as HDMI (19 pins) in a compact size for portable devices.

DVI-D Dual Link

Gender: Male 

Contains 24 pins, arranged in 3 rows of 8 pins with the flat ground bar off to the side. The interface provides two TMDS links. Most DVI applications will use this cable connection.

DVI-D Single Link

Gender: Male 

18 pin arranged in 2 groups of 9 pins with the flat ground bar off to one side.

Gender: Male 

Looks almost identical to DVI-D, except an additional 4 pins surround the flat offset ground bar. This interface was designed to carry both digital and analog signals.

Gender: Male 

While not an “official” standard according to DDWG, this connector type does allow a VGA device to connect to a DVI-I interface. Example: DVI output on a computer’s video card may be DVI-I and thus capable of supporting both digital and analog signals.

 

DisplayPort (DP)

Gender: Male 

Designed to connect high graphics to PC and displays. 20-pin connector uses TMDS link technology to send high bandwidth video and audio signals

BNC

Gender: Male 

Connectors are round plugs with bayonet-style locking system used on coaxial cables. They are frequently used for professional audio / video equipment and in CCTV and surveillance camera applications. Two most common uses are in a 3-BNC (RGB) component video and 5-BNC (RGBHV) component video cable.

DB9

Gender: Male 

Commonly used for RS-232 serial applications. Connector has 9 pins arranged in 2 rows (4 pins and 5 pins).

DB25

Gender: Male 

Used most often for parallel, RS-232 serial, or SCSI applications. Connector has 25 pins with two rows, top row has 13 pins, the bottom row has 12 pins.

HD15 (VGA)

Gender: Male

Same size as the DB9 connector, but has 3 rows of 5 pins. On most HD15 male connectors, one pin (pin 9) is missing in the middle row. Used as a video interface for monitors (also found on HD displays), and commonly known as VGA connector.

M1

Gender: Male

Transmitted signal can be analog or digital and is totally dependent upon the source device used. Mostly found on projectors. Has 30-pins: 3 rows of 10 pins with an offset ground bar (4 additional pins surround the ground bar, for an analog video signal).

RCA

Gender: Male 

It is used in several video applications, including composite video and other 75 Ohm applications. Older video formats such as analog and VHS should be connected using this composite interface.

DB37

Gender: Male 

Sometimes used with Cisco® networking and other applications that use RS-449 serial communication. The 37 pin connector has 2 rows: 19 pins and 18 pins.

RF (F-Type)

Gender: Male 

Common on coaxial cable for cable TV, satellite TV, and off-air TV antenna applications. Round with bayonet-style conductor in the center. Most f-type connectors are threaded. Some are merely pushed on and can be terminated by crimp, twist-on, or compression. A compression fitting is preferred, because it is the most secure, with the lowest amount of RF leakage.
