Usb3 3.0 Controller Riser Card Black Portable Data Transmission Small Pci- -e X1 Gold Finger Consumer Electronics 5gbps Desktop Description: PCI- E to USB3.0 Dual 19/20PIN expansion card USB3.0 features: The transmission speed is fast, and the theoretical transmission rate is 5Gbps/S, which is nearly 10 times faster than USB2.0 480Mbps/S; The output power is higher, and the output power of each port is 5V/1A, which is twice as high as that of USB 2.05v/0.5a. Adopt VL805 high-order main controller chip; PCI-Express interface is used, and four high-speed data transmission interfaces of USB3.0 interface are bridged by VL805 master control. Imported Alpha & Omega high-power PWM synchronous step-down DC power supply chip is adopted, and the big brand chip is worthy of trust. Low-loss alloy powder is die-cast, with low impedance, no lead end, small parasitic capacitance, firm structure, accurate product, lasting rust prevention, small volume and large current. Self-recovery fuse: Each 19P/20P output port is equipped with a 6V3A self-recovery fuse. When the USB device with short-circuit fault is externally connected, the high temperature generated by short-circuit current will instantly cause the inside the fuse to generate a high blocking state, thus limiting the short-circuit current. When the fault disappears, the temperature drops and the will automatically return to the low-resistance conducting state. Adopt multi-layer circuit board for lossless transmission: adopt four-layer circuit board: have very strong anti-interference ability; It effectively ensures the stability of PCI-E high-speed signal transmission, data integrity and impedance matching. PCI- -E X1 gold finger: PCI. -E 2.0 X1 contact gold finger, high gold plating: strong oxidation resistance, good conductivity and wear resistance. Interfaces can be flexibly matched: they can be expanded into two 19P/20P interfaces.
