Infineon USB-C 20Gbps Reference Design Works Over 5-Meter Passive Cables

By Indie Kings | October 2, 2026

Updated October 2, 2026: Infineon has released a reference design for a PCIe add-in card that puts two USB-C ports carrying 20Gbps of data across 5-meter passive cables, built around an ASMedia ASM4242 host controller and an Infineon EZ-PD CCG7 power delivery controller, and aimed at industrial machine vision equipment. The catch is that this is an engineering blueprint for factory equipment builders rather than a product: no price is announced, nothing is offered for purchase, and no retail expansion card is described.

Per PC Central, writing by Anthony York on October 1, 2026, Infineon has released a reference design for a USB-C 20Gbps PCIe add-in card, which PC Central abbreviates as AIC. PC Central describes the device as a reference design for a PCIe add-in card that puts 20Gbps of data across 5-meter passive cables, aimed at industrial machine vision systems. The article is filed under Accessories and Peripherals and under Other News.

The headline claim is a headline number: 20Gbps carried over five metres of cable that is passive, which PC Central's own summary line puts plainly. That combination is unusual enough that PC Central says it confirms 20Gbps transmission over 5-meter passive cables is achievable with current controller technology. The source also says the hardware solution allows manufacturers to maintain reliable data integrity across 5-meter passive cables.

That photograph shows two USB-C connectors being held in a hand. It is not the Infineon reference design card, not an industrial machine vision product, and it shows no card, no controller and no cable. It is here only so a reader can see what a USB-C connector physically looks like, since the connector is the one physical detail the source is specific about.

Twenty gigabits across five metres of passive cable

The downstream side of the card is two USB-C ports, per PC Central's specification block. Each of those two ports is capable of delivering 36W of power delivery output for connected devices. That gives a builder one data port with 36W, or two of them, depending on the equipment being built.

PC Central says the reference design centers on a PCIe expansion card that bridges high-speed computing with flexible peripheral connectivity. The upstream side is PCIe Gen4 x4, which PC Central says ensures robust data throughput to the host system. The card is therefore a bridge in both directions: data and power travel out over the USB-C ports, and the card itself sits in a PCIe slot on a host machine.

The distance claim is the part that matters for the stated application. PC Central frames the problem as industrial machine vision systems often struggling with signal degradation when connecting high-speed components over longer distances. A camera sensor on the far end of a factory cell is not going to be next to the host computer, so cable length is a design constraint rather than an afterthought.

One detail in that table deserves a note rather than a shrug. The cable is passive, so no active copper or optical conversion is described anywhere in the source. Passive is doing real work in that sentence, because a five metre passive run at 20Gbps is the whole claim being made, and the source does not describe any retimer, extender or active hub sitting between the card and the sensor.

A reference design is not a product

PC Central says this release provides a standardized hardware blueprint for industrial automation and machine vision projects. A blueprint is a design that a manufacturer re-implements or licenses, not a card that ships on a shelf. The distinction matters, because most hardware news written for a consumer audience would otherwise be read as "new expansion card available."

Nothing in the source supports that reading. There is no price, no availability date, no customer, no shipping information and no retail listing. PC Central says this reference architecture gives system integrators a validated path to implement long-distance high-speed data transfer without custom PHY development, which is an engineering benefit rather than a shopping opportunity.

The audience in that table is the whole story of this release. A system integrator building a scan cell needs a card that carries data five metres to a sensor and delivers 36W to whatever sits at the far end, and needs the signal integrity problem already solved. A desktop builder wants a card that fits a slot and enumerates on an operating system they already own. Those are different products with different customers, and the source only describes the first one.

The two controllers do the work

PC Central says engineers can build this solution using specific controller chips to handle the complex signal requirements. Two chips are named. The design integrates an ASMedia ASM4242 USB4 host controller to manage data transmission protocols, and it also employs an Infineon EZ-PD CCG7 USB PD controller to regulate power delivery and port negotiation.

The split of duties is what a reader should take from that sentence. The ASMedia part handles the data side, per PC Central. The Infineon part handles the power side, meaning both the 36W delivery and the negotiation that establishes what the far end is willing to accept. Infineon supplying the power half of a card whose data half comes from ASMedia is the notable structural fact here, because it means the company is not the sole silicon supplier on its own reference board.

The host side is PCIe Gen4 x4, per the source's specification block. PC Central says this ensures robust data throughput to the host system. How much of that upstream link is available to the downstream USB-C ports is not stated anywhere in the article, so any arithmetic comparing an upstream link to a downstream 20Gbps figure would be an assumption rather than a reported fact.

Per PC Central, Infineon states that this 20Gbps configuration provides twice the bandwidth of previous generation products. That is Infineon's own claim as relayed by PC Central. The referent for "previous generation products" is not stated in the source, and no baseline figure is given, so the claim cannot be checked against anything in the article.

What the source does not reconcile

There is an unresolved point inside the source itself, and it is worth stating plainly rather than smoothing over. The summary line and the headline describe a USB-C 20Gbps design. The body of the article describes the ASMedia ASM4242 as a USB4 host controller. PC Central does not explain how those two descriptions relate to each other.

That gap is not cosmetic. Whether the two downstream USB-C ports run USB4 or run a 20Gbps USB-C protocol is the single largest open question about this design, and the source leaves it open. Any reading of this card's downstream capability that resolves the ambiguity is adding information the source does not contain, so this article does not resolve it either.

PC Central says the company highlights that the design solves signal integrity challenges that typically limit industrial applications. That framing is consistent with the summary line, which is about distance and signal degradation rather than about a protocol generation. But the body calling the host controller a USB4 part is the reader's only signal pointing the other way, and it is not reconciled.

The bandwidth claim has its own problem, described above. Infineon states twice the bandwidth of previous generation products, and neither the name of that previous generation nor the baseline number appears in the source. Treat it as a vendor claim with a missing referent, not as a measured comparison.

Why machine vision needs this, and you might not

The stated use case is industrial machine vision in automated scanning and inspection workflows. PC Central says the 5-meter passive capability removes a common physical constraint in those workflows. A vision cell typically puts a sensor or a camera head some distance from the machine that stores and processes its output, and cable runs in that setting are long, routed through conduit, and often crossed by other cables.

Signal degradation over those distances is the specific problem PC Central names. The source frames it as industrial machine vision systems often struggling with signal degradation when connecting high-speed components over longer distances. Infineon's answer is a validated board design rather than a new cable, a new connector, or a claim about a new protocol.

PC Central says manufacturers can use this design to build systems that require both high-speed data and power delivery over extended distances. Both halves matter in a vision cell, because the far end of the cable may be a sensor head that needs to be powered as well as read. A design that delivered only data would leave the integrator solving power delivery separately.

None of that applies to a desktop. There is no game, no gaming accessory and no consumer scenario described anywhere in the source. The nearest thing to a consumer takeaway is that the underlying controllers and the passive cable result are reusable knowledge, but that is an inference rather than a claim in the source.

What it means for system integrators

The practical pitch, per PC Central, is that this reference architecture gives system integrators a validated path to implement long-distance high-speed data transfer without custom PHY development. Custom PHY development is expensive, slow and risky, and the source presents avoiding it as the central saving for a builder who otherwise has to solve the same problem from scratch.

PC Central says the reference design centers on a PCIe expansion card that bridges high-speed computing with flexible peripheral connectivity, which is the integrator's version of a done decision. The board is the bridge; the integrator's remaining work is the enclosure, the sensor, the software and the machine.

The honest limit is that the source names no integrator and no deployment. No company is described as having built a machine around this design, no factory is named, and no field result is reported. A reference design is a starting point that has been validated by the vendor, not evidence of a shipped product line, and the article does not claim otherwise.

The source also describes this as a standardized hardware blueprint for industrial automation and machine vision projects. Standardized in that sense means the design is meant to be repeatable, so more than one equipment maker can build the same card, and the manufacturer does not have to re-solve the signal integrity problem for each one.

What is not established

The following details are absent from the source and are listed here so they are not mistaken for omissions from this article. Each one would need separate sourcing before a builder or a buyer relies on it.

The first two rows in that table are the same problem in two forms, and they are the ones that matter most. Until the port protocol question is answered by Infineon or ASMedia documentation, "USB-C 20Gbps" and "USB4 host controller" remain two labels for a card whose downstream capability the source has not pinned down.

FAQ

What did Infineon release in October 2026?
Infineon released a reference design for a PCIe add-in card with two USB-C downstream ports, an ASMedia ASM4242 host controller and an Infineon EZ-PD CCG7 power delivery controller, per PC Central on October 1, 2026.

Can you buy this card?
No. PC Central describes a reference design, and no price, availability or retail listing is offered, so there is nothing to buy from this announcement.

Is this a USB4 card or a USB-C 20Gbps card?
PC Central's summary line calls it USB-C 20Gbps and the article body calls the ASM4242 a USB4 host controller. The source does not explain how those two descriptions relate, so the question is left open.

How long are the cables, and do they need active hardware?
The claim is 20Gbps over 5-meter passive cables. The source describes no active copper or optical conversion anywhere in the design.

How much power do the ports deliver?
PC Central's specification block lists 36W of power delivery output, and the article text says each of the two USB-C ports can deliver 36W to a connected device.

Does this matter for a desktop PC or a gaming build?
No application of that kind is described. The stated application is industrial machine vision in automated scanning and inspection workflows, aimed at system integrators building factory equipment.

Bottom Line

Infineon's release is an engineering blueprint for industrial equipment, not a consumer product. PC Central reports that the design puts 20Gbps across 5-meter passive cables on two USB-C ports with 36W of power delivery per port, using an ASMedia ASM4242 host controller and an Infineon EZ-PD CCG7 power delivery controller behind a PCIe Gen4 x4 upstream interface. The payoff for system integrators, per the source, is a validated path to long-distance data transfer without custom PHY development. The payoff for everyone else is that there is nothing to buy.

Two claims should be carried with their caveats attached. Infineon says the configuration provides twice the bandwidth of previous generation products, and no previous generation or baseline figure is named in the source. And the source describes the same card as both a USB-C 20Gbps design and a USB4 design without explaining the relationship between those two things, which leaves the downstream protocol unresolved.
