At end-2010, two-in-one modules with Triggering capabilities were proposed

2S-Pt module:From two-in-one to all-in-one
07 Sep 2011 / FV
Can be envisaged because Tk is fiber-rich
• Module becomes standalone building block– Front-end chip– LP-GBT– SF-VL– Ancillary electonics (control,
monitoring, aggregation, timing distribution)
– DC/DC converter

Conclusion
7 Nov 2011
• Phase II TK electronics R&D is under way• 3 chips in Si (CBC, FEAFS, VICTR), at least 5 more being
discussed (MPA, 3DDataFlow, LP-GBT, CBClight, Concentrator&Controller)
• Agressive packaging/interconnect technologies under investigation (C4, HDSubstrate, 3D, TSV, opto, …)
• Fallback paths are available (PS -> 2S, LP-GBT ->GBT, etc…)• Advanced CMOS processes (65nm for MPA and LP-GBT)• Very challenging program
– Avoid maintaining parallel developments for much longer– Concentrate effort– Be prepared for long development time– New collaborators welcome NOW
• Backend development options to be considered soon
