The market of USB 3.1 controllers is largely commanded by ASMedia and VIA Labs, who sell the lion’s share of USB 3.1 Gen 2 solutions either as standalone chips or as IP. However times may be changing, as there are two new kids on the block: Cypress with its 7-port USB 3.1 Gen 2 controller, and Zhaoxin with its ZX-200 chipset for its CPUs that supports USB 3.1 Gen 2 as well.

Cypress’s HX3PD USB 3.1 Gen 2 controller is designed primarily for multi-port USB hubs and displays featuring six USB 3.1 Gen 2 downstream ports (one with power delivery). The chip integrates everything necessary to build the aforementioned devices, including PHY, routing logic, dock management controller, USB-C bridge and so on. The product was demonstrated last month, so expect it to hit the market in the coming quarters. The HX3PD will compete against similar solutions and will not necessarily find its way inside PCs.

What will be used inside PCs is Zhaoxin’s ZX-200 chipset for the company’s KaiXian KX-5000 and the KaiSheng KH-20000. The core logic supports four PCIe 3.0 lanes, four SATA ports, a GbE controller, RGMII interface, two USB 3.1 Gen 2 connectors, three USB 3.1 Gen 1 headers, and six USB 2.0 ports. Zhaoxin says that its USB 3.1 Gen 2 controller has been developed entirely in-house and that it is the first of such controllers designed in China to get an interoperability certification from the USB Implementers Forum. In fact, the ZX-200 is probably among the most complex chipsets developed in China in general.

Zhaoxin introduced its ZX-200 chipset late last year, so it will likely be available in China shortly.

    Zhaoxin is the joint venture with VIA that are creating x86 CPUs using VIA's license to help alleviate China's reliance on foreign processors. It's a company to watch - if anyone has any availability into the Zhaoxin laptops available in China (for govt use so far I think?), please let me know. Reply

    So far they are just rebranded Via CPUs.

    These joint venture Chinese companies don't really develop their own IP but depend on licensing. And mostly they just want the money from Chinese gov.

    Yeah, so far rebrands or minor microarch updates. Seem to have plans for future designs though. Reply

    Govt use in China would most likely be in a Lenovo laptop - such as the ones they already use. Zhaoxin laptops wont exist sames as Intel or AMD laptops dont exist. Lenovo is Zhaoxin biggest partner - future planning on laptops etc for chip use defo. Reply

    It's not really gov use, but the big money from Chinese gov.

    1. Put other company into your pocket along with their IP
    2. Rebrand it as your own "innovation"
    3. ???
    4. Profit!

    Ohh.. VIA x86 CPUs brings back memories :) Reply

    I had a Cyrix Media GX along with a 3dfx voodoo on VIA chipset. Reply

    But what about USB 3.2 now? Reply

    What about it? We're talking current Gen - not future Gen. There's another article on Anandtech regarding 3.2. 3.1 here. Reply

    He’s right though. USB 3.2 has been the current spec since last September. USB 3.1 came out 5 years ago this month, yet there are still, near as makes no difference, zero USB 3.1 Gen 2 hubs available for purchase. I figure maybe device makers are saying screw it and just going straight to USB 3.2 Gen 2 x 2. Reply
