What is high-speed serial data testing?

High-speed serial data testing checks that wired interfaces such as USB, HDMI, DisplayPort, PCIe and Ethernet transfer data reliably at their rated speeds. It covers physical-layer signal integrity, protocol behaviour, interoperability with other devices and readiness for certification

Which high-speed interfaces does Resillion support?

We support USB from 2.0 to USB4 and Type-C, HDMI up to 2.1 including FRL and ARC/eARC, DisplayPort, Ethernet from 1G to multi-gigabit and automotive, PCIe Gen 1 to Gen 6, ASA Motion Link, MIPI A-PHY and Open-GMSL, across consumer, industrial and automotive products.

What makes Resillion's high-speed testing different?

Our Belgian lab combines over €2 million of advanced test equipment, a technology partnership with Keysight, USB-IF authorised status and a library of 500+ USB chargers. That lets us pair detailed physical-layer analysis with automated test suites and real-world interoperability testing.

Is Resillion a USB-IF authorised test lab?

Yes. Resillion (Belgium NV) is a USB-IF Authorised Independent Test Lab. We run USB-IF certification testing for USB Type-C, USB Power Delivery and USB 3.2 products, and EU conformity testing to USB-IF specifications for the common charger rules.

Can Resillion certify HDMI, DisplayPort and PCIe products?

We test HDMI, DisplayPort and PCIe products for conformance, signal integrity, protocol behaviour and interoperability before formal certification. This finds issues early so your product is ready when it goes to the relevant certification programme.

What does the EU common charger rule mean for my product?

Phones, tablets, cameras, headphones and other small devices sold in the EU must charge over USB-C, and laptops have been included since 28 April 2026. Products charging above 15 W must also support USB Power Delivery, so USB-C and USB PD testing is now a launch requirement.

Why is signal integrity testing important?

At high data rates, small amounts of jitter, loss or eye closure can cause unstable links and failed compliance tests. Signal integrity testing measures these effects early, while the board design can still change.

Which automotive interfaces can Resillion test?

We test Automotive Ethernet, including 100BASE-T1 to the OPEN Alliance TC8 specification, plus ASA Motion Link, MIPI A-PHY, DisplayPort Automotive and Open-GMSL links for cameras, sensors and displays.

When should we start interface testing?

Start before formal certification, while hardware and firmware can still change. Pre-compliance testing and debug find signal, protocol and interoperability issues when they are cheaper to fix and less likely to delay launch.

Why high-speed serial data testing matters

Every jump in data rate shrinks the margin for error. At USB4, HDMI 2.1 or PCIe Gen 6 speeds, a small loss in signal quality can mean dropped links, failed compliance tests and a missed launch window. Resillion tests the wired interfaces that carry data, video and power through modern products, from USB and HDMI to PCIe, Ethernet and automotive SerDes links. Our upgraded high-speed lab in Belgium uses Keysight instrumentation, and as a USB-IF Authorised Independent Test Lab we can take USB products all the way to certification.

The aim: Interfaces that pass compliance first time and work reliably with every device they connect to.

What we offer

We test the high-speed wired interfaces in consumer, commercial, industrial and automotive products at three levels: physical-layer signal integrity (jitter, eye diagrams and bit error rates), protocol behaviour (link training, error handling and throughput) and cross-vendor interoperability.

For USB, we are a USB-IF Authorised Independent Test Lab, so one team can take you from pre-compliance and debug to formal certification. For HDMI, DisplayPort, PCIe, Ethernet, automotive links and photonics, we get you ready for certification. With Total Quality guiding delivery, results connect with wider quality and cyber assurance.
