Science Controller MTCA / µTCA


Metlino is an extension for MicroTCA carrier hub (MCH) optimized for use with Sinara hardware.

Metlino together with the MCH module serves as the crate master, controlling µTCA peripherals (such as Sayma) in real-time by sending ARTIQ DRTIO commands over the crate backplane (MCH Fabric D-G). It can also control additional ARTIQ peripherals via the SFP and VHDCI connectors on the front panel.

Metlino can be used either as the ARTIQ master or as an ARTIQ DRTIO slave connected to the master via DRTIO. In the master mode, it receives commands from the host PC via Ethernet, while in the slave mode, it receives commands from the ARTIQ master via DRTIO link.

Metlino provides 64 LVDS IOs, accessible through 2 VHDCI connectors, as well as 1 FMC LPC. The VHDCIs are compatible with the VHDCI carrier and Eurocard Extension Modules and can be used to drive such EEMs like Sampler, Urukul or DIO BNC.
