SPAC System Status

Spac Slaves :

• 5 SPAC3 ASICs received and tested : OK !•~100 SPAC3 ASICs will arrive in Paris this week

should be available for FE boards quite quickly

•Irradiation Test in preparation (test by early june ):

•4 ASICs (3 receivers, 1 repeater) will be fully tested•1 monitoring VME board has been developed for the test•6 ASICs will be put on another card•Test Bench developed in C, C++ is fully functional

implementation of a GUI is ongoing

SPAC System StatusImplementation of Spac Bus under study :

Simulation using SpecctraQuest underway…

Spac Bus Optical LinkMockup built in Paris : radhard solution found and

tested.- Emitter : FEB optical link ok ! - Receiver : Rad-hard Cern RX40 + Fermionics Pin diode ok ! Packaging RX40 + pin diode to be studied for assembly on

controller

e.g. Barrel FEC bus :

Question : Can we drive 22 SPACs as needed on the EMEC Special ½ crate ? Can it be tested at BNL ?

Controller Board Design Status

• TTC connectors : – USB mini-B/mini-B : ok !– Halogen free cables will have to be produced

(Molex)

• Rad-tol TTC fan-out : – Fan out based on a tree of 10H116 chips had been

tested : ok !• 10H116 qualified and ordered (thanks to Nevis)

• Optical reception of TTC signal :– Studies still underway :

• receiver used for SPAC does not work at 160 MHz.• Other solutions under investigation

Details on TTC connectors and

cablesOn Board : USB mini-B receptacle (SMT) version

Molex 54819b (www.molex.com)

Cables : Halogen free, L=40 cm mini-B/mini-B custom cable based on ref. Molex 59204

On the Controller, mini-B receptable installed by pair using either :

• PCB with 3.2 mm local thickness with standard mini-B connector • Standard 2.4 mm standard PCB + thread whirled cable connectors

Prospects• A lot of work has been done :

– Test of SPAC3 ASICs : ok !

– Test Bench set up for Irradiation test of SPAC ASICs : ok !– Rad Hard Optical solution tested and qualified for the SPAC :

ok !– TTC connectors (USB mini-B) and TTC Fan out on the controller :

ok !

• Every SPAC system aspects is under control except :– Irradiation tests for SPAC3 Asic to be performed– Bus loading for EMEC Special crate is critical

• Controller Board design is achieved except :– Optical reception of the TTC signal still under study– Final design of the board (placement and routing) :

easy !
