36. ETD : news since Perugia
Some progress was done on different elements of the architecture:
Clock and control links : a commercial chipset from National Semiconductor has been found which seems to fullfil the requirements concerning the fixed latency and the clock jitter ( DS92LV18)
Its technology (CMOS8 => 0.25µ) has been validated in radiation up to 50krads in ATLAS.
It also has to be validated by us, especially looking at SEUs and SELs
=> see talk from Alberto Aloisio in the Wednesday afternoon ETD session.
The LOC2 chip, which is a 16-bit/160MHz serializer designed by our colleagues from Dallas for the upgrade of the LARG electronics of ATLAS seems to be a potential candidate for SVT data readout at 2.5Gbits/s
Work however continues on the commercial TLK2711A chip which was originally selected for data readout => validation in radiation
Work has started at LAL on thinking of the implementation of the FCTS system in a crate => see talk from Daniel Charlet
Discussions started around a new design of the ROM in Padova, Legnaro and Bologna
The investigated idea is to drive a 10Gbit-Ethernet link directly from the readout electronics without the assistance of microprocessors and software.

37. ETD : expectations from this workshop
In Perugia, subdetectors started presenting the way they will deal with the overall architecture for their own design:
This should appear more clearly this time since the last months allowed people to understand the architecture more precisely
For instance, we had a very fruitful discussion with our calorimeter colleagues a few weeks ago.
Now we hope to get close to be able to describe functional subsystems coherent with each other at the experiment level
Level 1 Trigger still remains an uncovered feature.
Steffen Luitz was given the charge of steering the DAQ/online of SuperB.
We have to define the boundaries of this new item and define its connections with other subsystems.
A working meeting will take place at CERN beginning of November, including discussions about the Level 1 Trigger
