iso-SPI #25
Description
We must build several custom front-ends for photonic sensors, like superconducting nanowire detectors for space-to-ground QKD.
The idea is to reuse this board and add 3 ISO-SPI transceivers and DIOT support.
In this way, with a single AUX_PSU module and primitive AFE boards (just SPI ADC/DAC), we can build a complex system with minimal HW RnD.
So, the idea is to add a mezzanine with LTC6820, LVDS transceivers, isolation transformers and SPE connectors.
Is integrating the power supply and isolated digital signals in one M10 connector a good idea?
Alternatively, we could replace M10 with RJ45 connectors and use standard Ethernet cables for power supply and communication.
RJ50(10P10C) could also be a good option to avoid plugging Ethernet or LVDS cable into a 15V supply.
