The objective of the project has been to design, develop and validate a prototype of a mixed signal ASIC (EOCD) to be used as output command driver in on board computers.
The key issues of the project were implementation of the output command driver in a high voltage ASIC technology, I3T80 from OnSemi. The design has also addressed key requirements related to ESD, radiation and SEE.
The use of output commands in on board computers and data handling systems is a common task. Up to now this functionality has been performed by an ASIC that is now longer available. The EOCD provides means to increase level of integration, reduces needed PCB area and reduces power consumption compared to other solutions based on discrete implementation.
The development was divided in the following work packages:
The project started in September 2011 and the tape-out for MPW occurred during the last quarter of 2012. The manufactured EOCD Demo ASICs were received in April 2013 and the validation was completed in December 2013.
The EOCD DEMO ASIC validation has been completed. The next steps are related to optimising the design based on findings from the so far completed work in order to have version that can be used in flight applications. This includes formal industrialisation of the EOCD ASIC
