We have developed a second generation UVOIR MKID readout based on the CASPER ROACH2 board and custom ADC/DAC and RF boards designed in collaboration with Fermilab.
These boards feature:
Dual 2 GSPS 12-bit ADCs
Dual 2 GSPS 16-bit DACs
4-8.5 GHz band reads out 1024 pixels in 2 GHz of bandwith
Scalable to >30 kpix
$5-10/pixel exluding FPGAs and HEMTs
A full description of the readout is avaialble on arxiv.
We hope to soon release the designs of these boards with an open source license. Firmware is already avaialble at: https://github.com/MazinLab/MKIDReadout
