High Speed and High Performance Analog to Digital Converters (ADC) are a key component for scientific payloads, especially for multi-channel instruments with challenging requirements regarding thermal stability, power consumption, electronic noise, volume and mass such as the LISA mission. In particular the LISA phasemeter requires a large amount of channels and respective ADC (80). Currently on the market available ADC with adequate performance requirements (required: 300 Mhz analogue bandwidth, > 80 Mhz sampling rate) such as for example the AD9246S or the RHF1401 do however not comply with the stringent power dissipation (thermal) requirements (e.g. 20/100 mW target/goal) of the LISA phasemeter. The usage of this 4channel ADC would lead to an estimated reduction of power and mass of the LISA payload by 40 W respectively 12 kg compared to the existing single channel options and greatly simplify the already complex phasemeter design. Additionally this 4channel ADC is a very generic component that will be available and useful for many other payloads. This activity continues a successful previous development 20263/06/NL/LvH) of a proof-of concept Single-ADC which reached prototype level at TRL3 and aims to expand the design to quad-channel layout and further expanding interface options matching generic instrument requirements. The resulting Quad-ADC EM’s performance shall be tested and verified. The activity shall also include a definition of a potential follow-on characterization campaign, which is however not part of this activity.
