Description
Sampling high bandwidth signals above 1 GHz in MTCA.4 on an AMC
digitizer with an analog front end located on the RTM side, requires a
new type of Zone3 connection.
The analog classes based on differential pairs connectors suffer from
intense cross talk if the signal frequency rises above 300 MHz.
DESY is planning to introduce a new analog class based on single ended
coaxial connectors between AMC and RTM. The first board using this new
coaxial
connectors will be the direct sampling digitizer DAMC-DS800. For
evaluating and testing the concept of direct sampling in MTCA.4, DESY
has built a cost efficient
direct sampling FMC digitizer board. A new concept for an analog Zone3
class for MTCA.4 and the AMC/FMC digitizers will be presented.
