Teledyne e2v Develops Space Computing Reference Design featuring Microchip’s Radiation-Tolerant Gigabit Ethernet PHYs

18/10/2023

Teledyne e2v, in collaboration with Microchip Technology, is developing a space computing reference design to enable high-speed data routing in space applications. This innovative design will be showcased at the European Data Handling & Data Processing Conference (EDHPC) in October 2023.
 
The reference design combines Teledyne e2v's Radiation Tolerant Qormino QLS1046-Space processing platform with Microchip's data communication technology. It is fully radiation-tolerant and offers robust, high-performance processing capabilities along with enhanced subsystem connectivity.
 
The QLS1046-Space platform features quad Arm Cortex-A72 cores with 30,000 DMIPS computing capability and 4 to 8 GB of high-speed DDR4 memory. It can process and route large volumes of incoming data from various sources, such as RF front ends, high-resolution image sensors, and radars in spacecraft.
 
 
  
The high-speed connectivity is ensured by Microchip's radiation-tolerant Ethernet PHYs. The reference design utilizes the VSC8541RT PHY for two RGMII links and the VSC8574RT for two SGMII interfaces, providing a total of four Gigabit Ethernet connections. In the future, the design can support up to seven Ethernet interfaces using all available high-speed interfaces on the QLS1046-Space, and up to 18 with the upcoming LX2160-Space.
 
This design enables high-speed data transfers between the QSL1046-Space and other devices within the satellite or spacecraft. It has various applications, including Earth observation, SATCOM, defense in space, and space debris monitoring.
 
According to Thomas Porchez, an Application Engineer at Teledyne e2v, the decentralized architecture of modern space hardware demands increased performance for advanced telecommunication, real-time image processing, AI-driven analysis, and navigation. The collaboration with Microchip has enhanced the interfacing capabilities of the QLS1046-Space, resulting in accelerated speeds and extended propagation range, meeting the demands of space customers for edge computing applications.
 
Microchip's radiation-tolerant Gigabit Ethernet PHYs integrated into Teledyne e2v's space computing reference design provide high reliability and high-speed connectivity for various space applications.
