eRTM15 LLRF White Rabbit
Project description
The eRTM15-LLRF-WR project is composed by two MTCA eRTM modules: a WR
Node module and a RF module.
The WR node is a eRTM module, designed to be inserted into eRTM Slot 14,
with a redundant fiber connection to a White Rabbit network. It controls
the RF module through a board-to-board connector.
The RF module is designed to be inserted into eRTM Slot 15. It provides
clocks and LO/REF signals through the specific LLRF backplane to µRTM
and AMC
slots.
