Project Example – Single Pair Ethernet Board


Single Pair Ethernet (SPE) provides a low-cost infrastructure for automotive, industrial, and IoT applications. Instead of the traditional 8-wire twisted pair connection, SPE uses a thin 2-wire cable and small connector, reducing weight and costs while retaining support for both data and power transfer. 
Because it is based on Ethernet it directly works with the ubiquitously available equipment and installed network infrastructure. It eliminates any expensive protocol conversions that were needed previously to connect legacy industry equipment.

Our customer, a leading provider of factory and lab test equipment, was looking to add SPE test capability to their system. They asked AimValley to do the design of the SPE hardware module.

Customer Objectives

Using AimValley as a partner, experienced in complex system design, and an expert on Ethernet, synchronization, and SPE board designs, the new test module was delivered in a shorter interval. This significantly decreased risks and allowed the customer to focus on the development of new test applications and the user interfaces for the SPE test module.

Results and Added Value


Using our expertise on SPE technology and FPGA based solutions, the design was completed on time and without any risk of re-do or non-compliance. Our first-time-right execution resulted in a quick time-to-market.


The highly configurable design was quickly integrated into the existing test solutions, supporting many different synchronization test scenarios. The new module is 100% compatible with the system backplane, and stays well within allocated power budget. The customer enters the automotive and industry 4.0 markets with SPE test solutions.


The SPE module design team worked closely with the customer’s product architecture and software teams to ensure full compatibility with the system backplane and electrical interfaces.


During the definition phase AimValley created a flexible clock and PLL architecture taking advantage of our extensive knowledge of synchronization technologies and solutions.
