LVDS Application Workshop
29 June 2011, ESCAPE Dance Room, ESTEC
The use of LVDS on board of satellites has become more and more popular. For example SpaceWire links are based on LVDS but it is also used for the distribution of many other signal types within a PCB, units and between boxes.
Recently some problems have been observed regarding the reliable operation of LVDS based links on ESA missions. Questions have been raise during ESA project reviews regarding the reliable implementation and verification of LVDS interfaces and connections as well as on their robustness in case of possible failure cases in the system.
The LVDS Application Workshop aims to bring together experts from component vendors, equipment suppliers, system integrators and agencies to discuss experiences, lessons learned and to exchange best practices and ideas for the implementation and testing of LVDS links. The second part of the day will focus on capturing the user needs and requirements for the next generation of LVDS driver/receiver/repeater components and ASIC / FPGA interfaces. This shall cover the LVDS functional and electrical characteristics and the type of components needed in the future. The requirements identified in this part of the workshop may be used as input for future developments in ESA programs.
