What we offer:

State-of-the-art testing lab
Our dedicated high-speed serial data laboratory is equipped with advanced test equipment, including industry-leading signal analysers, oscilloscopes and automation tools. This infrastructure allows for repeatable and reusable physical layer testing, giving you the precision and confidence needed for certification and market readiness.

Physical layer testing
We assess signal integrity, jitter, eye diagrams and bit error rates to ensure that your design performs reliably at high data rates. By replicating real-world electrical conditions, we identify and correct potential performance bottlenecks before they become costly post-launch issues.

Protocol validation
Our engineers verify correct implementation of link training, error handling and data throughput across a range of high-speed protocols. This ensures that every device not only meets specification but delivers the consistent, high-performance communication users expect.

Interoperability testing
Resillion performs extensive cross-vendor and cross-platform compatibility testing, validating how your product interacts within diverse ecosystems. By identifying integration issues early, we help you reduce customer-impacting defects and improve reliability across the entire device lifecycle.

Standards leadership

Resillion is a member of USB Implementers Forum (USB-IF), Automotive SerDes Alliance (ASA), contributor to MIPI A-PHY development, and partnered with Keysight for advanced measurement capabilities.

What is high-speed serial data testing?

High-speed serial data testing validates the performance, reliability, and compliance of data interfaces such as USB, HDMI, Ethernet, PCIe, ASA and MIPI A-PHY. It ensures your products handle fast data transfer without signal loss, jitter, or interoperability issues.

Why is physical layer testing important?

Physical layer testing verifies signal integrity - including parameters like eye diagrams, jitter and bit error rates - to ensure stable, high-quality data transmission. This step is critical to achieving certification and reliable performance in real-world environments.

Which high-speed interfaces does Resillion support?

Resillion provides end-to-end validation for USB (2.0–USB4), HDMI (up to 2.1), Ethernet (1G to multi-gigabit and automotive), PCIe (Gen 1–6), ASA, and MIPI A-PHY. We work across consumer, industrial, and automotive applications.

What makes Resillion’s high-speed testing different?

Our labs are equipped with over €2 million in advanced test equipment, enhanced through partnerships with Keysight Technologies and other leading vendors. This allows us to combine automated test suites, detailed physical-layer analysis, and real-world validation for unparalleled precision.

Can Resillion support certification for my product?

Absolutely. Resillion is a member of the USB-IF, Automotive SerDes Alliance (ASA), and a contributor to MIPI A-PHY development. We provide guidance, pre-testing, and official certification support to help you meet all relevant compliance requirements.
