921 Connectors, Interconnects

USB Connectors

USB (Universal Serial Bus) is an industry standard intended to replace the variety of existing ports and connectors, such as parallel ports, serial ports, FireWire and MIDI. It is largely used for connecting digital peripherals, such as cameras, printers, scanners, keyboards, and mice.

USB has a maximum transfer rate of 12 Mbps and supports both unidirectional (point-to-point) and bidirectional (bus) data transfer. It uses a 4-pin connector, providing two power and two data lines. Its plug-and-play design allows for easy installation and removal of peripherals.

The 921 application of USB connectors includes connecting external peripherals, such as mice, keyboards, digital cameras, and portable media devices like iPod, to PCs or laptops. It is also used for transferring data between PCs and peripherals. For example, photos taken by digital cameras can be directly transferred to computers through USB connections.

DVI Connectors

DVI (Digital Video Interface) is a digital interface used primarily for connecting computers to flat panel displays, digital projectors, and digital TVs. It was developed by the Digital Display Working Group (DDWG) and is one of the first video standards to support both digital and analog video signals.

The 921 application of DVI connectors includes connecting a PC to a high-definition (HD) TV or computer monitor. DVI is also used for connecting a set-top box or media player to a monitor or TV. Additionally, DVI connectors are used in digital projectors for connecting to computers.

DVI connectors come in a variety of types, including DVI-A, DVI-D, and DVI-I. The DVI-A connector supports analog-only signals, while the DVI-D supports digital-only signals. The DVI-I combines the capabilities of both and can support both analog and digital signals.

HDMI Connectors

HDMI (High-Definition Multimedia Interface) is an industry-standard connector for digital audio/video devices, such as HDTVs, Blu-ray players, digital media players, game consoles, and set-top boxes. It is designed to transmit uncompressed high-definition video and multichannel digital audio, and uses a 19-pin plug.

The 921 application of HDMI connectors includes connecting a computer to an HDTV or digital projector. It is also used for connecting gaming consoles, Blu-ray players, digital media players, and set-top boxes to an HDTV. Additionally, HDMI is used for connecting home theater components, such as speakers and amplifiers, to a TV.

HDMI supports the transfer of uncompressed digital video and audio in eight different formats, including 480i, 480p, 720p, 1080i, and 1080p. It also supports 3D video and multichannel audio, such as Dolby Digital 5.1, DTS, and others.
