The USB interface uses Weifeng VL822 and VL817 for interface expansion, VL103 for USB-C interface control, and the built-in Chuangwei GL3224 for card reader function.Inside the fuselage, two PCBs are combined, and the corresponding heating chip is cooled with a heat conduction pad and an aluminum alloy heat sink to ensure long-term stable and reliable operation.
The superior USB-C multi-function dock D026A uses an aluminum alloy shell. The body shell is gray after anodic oxidation treatment, and the surface is fine with sandblasting technology. The whole product is very small and does not occupy space.This docking station has four 3A1C interfaces, two SD/Micro SD card slots, HDMI and Gigabit network interfaces.The data transmission speed is fast, and it can also listen to music while charging. The network interface has an indicator light which is more convenient to check the connection status and fully meet the daily needs.
Through disassembly, it is found that the charging head network uses chips from many well-known manufacturers in the industry, such as ITE Lianyang's IT6564FN, Chuangwei GL3224, Ruiyu's RTL8153, Weisheng's VL817-Q7 and VL102-Q4, Cmedia's HS-100B, and Silijie's step-up and step-down IC, with solid materials.
In addition, the front and back of the PCB board are insulated and protected by plastic. All interfaces are countersunk through hole welding, which not only reduces the thickness of the product but also enhances its firmness. The USB-C cable is more robust and durable than ordinary data cables.
The VA-DK001 docking station launched by VAVA supports connecting to the notebook through the USB-C interface, connecting the external power supply, providing the notebook with USB PD power supply and interface expansion. The docking station has two HDMI interfaces, which can expand two screen displays.The docking station has multiple USB interfaces to facilitate the connection of storage devices and peripherals.It also supports wireless charging function, realizing one-stop charging and expansion function, and simplifying desktop display.
The charging head network learned through disassembly that this docking station uses the STDP4320 conversion chip of MagaChips inside to convert the DP signal of the USB-C interface into two signals, and then convert the two channels of the PS8402A of the Perry PS8402A into HDMI output.The internal power conversion of the docking station uses the Ansome NCP81239 synchronous voltage rise and fall controller, uses Weifeng Electronics VP230 for PD interface control, two VL817s for interface distribution, and VL212 for interface expansion.
Several REALTEK Ruiyu transfer chips are also used in the docking station, among which RTS5306E is used for transfer of card readers in the docking station, ALC4040 is used for audio interface output, and RTL8153B is used for transfer of wired network.The docking station also uses two Silijie voltage drop chips for internal power supply of the docking station.This docking station has comprehensive functions and is a good assistant for office notebooks.
Xiaoxin USB-C five in one multi-functional docking station
Xiaoxin's expansion dock is designed in gray, and the front and back shells are double plastic twill covers of the same design, which is very light.The docking station is equipped with USB-C braided wire, which is dirt resistant and durable.In addition, the side body of the machine body is equipped with a cable slot, which can be stored when the USB-C cable is not in use, so it is convenient to carry and not messy.The docking station has three USB-A interfaces, 100W USB-C charging interface and HDMI interface, which support the use of mobile phones and computers.
The charging head network learned through disassembly that Xiaoxin's docking station adopts the micro drive video conversion scheme, uses the EP9631G chip for docking station function control, uses the Ruiyu VL817 chip for USB-A interface expansion, and has a built-in Tuerwei IM2605 for voltage up and voltage down conversion, providing a stable 5V power supply for the USB port and improving compatibility.All interfaces of the docking station are welded by sinking plates to reduce the thickness, and are equipped with over-current protection chips, which are stable and reliable.
As an important expansion device for new laptops in recent years, the USB-C Docking Station has greatly solved the thickness problem of multiple interfaces carried by traditional laptops. Multiple devices can be connected to laptops through the Docking Station, which not only simplifies the purchase of laptops, but also makes it more convenient to carry them daily, solving the problems of consumers.
Through disassembly, it was found that the more recently these 38 docking stations were launched, the more interfaces and the corresponding performance tended to improve.Many of them support USB3.0 data transmission and 4K resolution HDMI video output, which can meet the basic needs of most users.Some also have SD and TF card readers, wired network connection and VGA video output interface, which can be better compatible with traditional old-fashioned display devices.
