SEE characterization for a Quad 12-bit 1.6 GSps ADC, Digitizing up to 6.4 GSps (April 2021)

The EV12AQ600 is a quad channel 12-bit 1.6GSps ADC, with a Cross-Point-Switch which allows multi-mode operation with the capability to interleave the four independent cores in order to reach higher sampling rates, up to 6.4GSps. This device is intended for space applications, particularly the Earth observation SAR, the telecommunication MIMO and the ultra wideband satellite digital receivers. After a successfully Total Ionizing Dose test done with previous devices (with a low dose rate of 36Rad/h, and up to a total dose of 150krad), it was submitted to an heavy ions test, in order to evaluate its sensibility to Single Event Effect up to a LET of 67 MeV.cm²/mg. This test was performed at RADEF (University of Jyväskylä) in November 2020. The result is a total immunity to SEL, no latch-up has been detected, and a very low number of even exists for the synchronization signals. This device is our first data convertor with a serial link, using the EsiStream standard, and some SEFI were localized on this functionality, however, the device has proved its suitability to the more severe space environment.
