Data Sheet: GORE® Space Cables and Assemblies, Low Voltage Differential Signaling (LVDS) Interconnects
Data Sheets, 699.01 KB
On any space mission, data integrity is paramount to maintaining communication across spacecraft systems, and the cables connecting these systems directly impact quality and speed. To help increase data integrity among spacecraft systems, W. L. Gore & Associates offers GORE® Space Cables and Assemblies, Low Voltage Differential Signaling (LVDS) Interconnects for traditional space applications. They are proven to offer the best signal integrity thanks to their robust design and outstanding electrical performance.
Increase Data Integrity Among Electrical Systems
Data integrity is key to maintaining communication among spacecraft systems during a mission. The cables that connect the systems have a direct impact on the quality of the data and the speed of transmission. GORE® Low Voltage Differential Signaling (LVDS) Interconnects offer excellent signal integrity due to the combination of their robust design and their outstanding electrical performance, and are listed on the ESA QPL (Qualified Parts List).
GORE LVDS Interconnects reduce time delay and skew of signal transmission, while consuming less power and minimizing electromagnetic interference. Their small size and minimum bending radius allow for easy installation in tight spaces. Their light weight decreases mass, thereby reducing the amount of energy needed to launch the vehicle into space. The high number of individual lines available in each bundle increases the cable’s flexibility and makes it easier to route the cable.
The Science Behind the Cables
The key to the outstanding performance of GORE LVDS Interconnects is the proprietary material used in the cable insulation — expanded polytetrafluoroethylene (ePTFE). This high-performance insulation provides excellent signal control for applications where tight impedance control is necessary. Expanded PTFE is both chemically inert and thermally stable, which allows GORE LVDS Interconnects to be used in tight spaces without compromising the strength and quality of signal transmission.
Features & Benefits
GORE LVDS Interconnects dependably feature:
- tightest-available 100 ohm impedance of individual signal pairs
- low signal attenuation and crosstalk
- good EMC performance
- Twinax design based on ESA 3902/002
- multiple connector options
- frequencies up to 3 Gbit/s range
- vibration and shock resistance through QTP performance
By pairing these features with the material benefits of PTFE, our cables deliver:
- excellent signal integrity, minimum noise, tight impedance control and outstanding EMC performance
- high transmission speed from synchronously matched interfaces
- outstanding clock synchronization between individual lines that distribute time-sensitive signals
- easier installation resulting from small size and tighter bending radius
- valued reliability delivered from an ESA-qualified and a DIN EN ISO 9001:2008-certified manufacturing facility
Additionally, Gore’s worldwide engineering team provides sales and technical support. If you have any questions about GORE LVDS Interconnects, please contact us.
