USB, DVI, HDMI Connectors

USB, DVI and HDMI connectors are currently the three most commonly used types of connectors in the field of computer video and audio signal transmission. The XM7B-0442 connector is categorized as a USB connector.

What is an XM7B-0442 connector?

XM7B-0442, developed by the Universal Serial Bus Organization, is a USB 2.0 type-A connector with two rows of 7-pin contacts. This connector is typically used for connecting a high-speed USB device or peripheral to a computer. The connector’s design is optimized to reduce the risk of static discharge, and to ensure signal integrity and reliability.

Application field

XM7B-0442 connectors are primarily used in the field of computer audio and video, where they are used to transmit signals from a computer to a device or peripheral. These connectors can also be used for data and power connections between a computer and a USB-based device. This type of connector is also used for audio and video transmission in a variety of consumer electronic products.

Working principle

XM7B-0442 supports data transmission rates up to 480 Mbps, and is backward compatible with USB 1.1 and USB 2.0 standards. The data transmission from USB-A Connector to the device is divided into four stages: power supply, configuration stage, data transmission stage and an optional disconnection stage.

When the XM7B-0442 USB type-A connector is connected to the USB type-B connector of a peripheral device, the power supply stage begins. During this stage, the voltage between the two pins on the USB type-A connector is measured and the device is readied for the configuration stage. This is followed by the configuration stage, in which the device is configured to recognize the host and receive signals. Once the device is configured, the data transmission stage begins, and data is transferred between the device and the computer via the two pins on the USB connector.

Finally, at the disconnection stage, the two lines are disconnected from each other, and the USB port is reset and the power is turned off. The device then returns back to the power supply state and the entire process is repeated when the device is again connected.

Conclusion

The XM7B-0442 connector is a USB type-A connector with two rows of 7-pin contacts. This type of connector is used for connecting a high-speed USB device or peripheral to a computer, and is frequently used in the field of computer audio and video. XM7B-0442 connectors support data transmission rates up to 480 Mbps, and work by following a four-stage process: power supply, configuration, data transmission and disconnection.
