IEEE-1394, As a typical representative of serial digital interfaces, it has two forms: 6-pin and 4-pin. Among them, the 6-pin interface is hexagonal, while the 4-pin interface is a small quadrilateral. The core difference between the two lies in their different power supply capabilities - the 6-pin interface can provide power to connected devices through wiring, ensuring the continuity and stability of signal transmission.
In depth analysis of the 6-pin interface reveals that 4 pins are dedicated to data signal transmission, while the remaining 2 pins serve as power cords to provide electrical support for the device. In contrast, the 4-pin interface cannot achieve power supply function due to the lack of power pins. This design difference also determines their application scenarios on different devices: 6-pin interfaces are more common in desktop computers with ample space, while 4-pin interfaces are more common in home appliances such as laptops, all-in-one computers, and digital cameras due to space limitations and other factors.
The six pin IEEE-1394 connector developed and produced by TXGA not only has a data transmission rate of up to 400Mbps, but also supports power supply for external devices, achieving stable and efficient long-distance bidirectional data transmission. This feature makes it an ideal choice for meeting the high-quality long-distance transmission needs of multimedia devices.
