Power Supply Tot ~5620 W- Wiener proposal -

• 5V: AUX expected need ~80 W→ 16 A/AUX →16 A*16 = 256 A + some spare current for VME → requested 260-270 A- ~ 1350 W;

+ 300 W for 4 SSBs = 1650 W; → 330 A needed on 5 V Wiener proposal: 3 modules 115 A each for a total of 345 A

• 14 V: AMchip core; goal~128 W→9.2 A/AMB→9.2 A *16 = 147 A-2048W Wiener proposal: 4 modules @15 V 550 W each for a total of 2200 W

@14 V 184 A 2200 W

• 48 V: for SerDes and fanouts: ~120 W→2,5 A/AMB →2,5 A *16 = 40 A 1920 W-300W

• Wiener proposal: 3 modules 13.5 A each for a total of 40.5 A

1st HipothesisEarly 2013

In summary: 10 module maximum in a Wiener box• 5V: 3 modules 115 A each for a total of 345 A; Needed ~240 A

proposal: go down to 2 modules 230 A and integrate with 14 V

• 14 V: 4 modules for a total of 184 A; Needed ~147 A for Amchip core only; use ex 3.3 V pins in J1proposal: go up to 5 modules 230 A and use it also in J0 for SSB and AUX

• 48 V: 3 modules for a total of 40,5 A; Needed ~40 A for AMB only – use V1,V2 pins in J1

Why the proposal: more balanced currents between 5 V and 14 V; more redundancy on 14 V –

possible to balance AMB-SSB-AUX needs

1st Hipothesis early 2013

Update -Option A Power needed/crate~5870 W Wiener: not standard

• 5V: VME + SSB → SSB 90 W/board tot 360 W (70 A); Wiener proposal: 1 module 115 A for a total of 575 W

• 12 V: Amchip core + AUX board• AMchip core; goal~128 W→10.7 A/AMB→10.7 A *16 = 170, 7 A-2048W • AUX card; 90 W →7,5 A/AUX→7.5 A *16 = 120 A- 1440 W Wiener proposal: 6 modules @12 V 600 W each for a total of 3500 W

@12 V 50 A each for a total of 300 A (3600 W) ???

• 48 V: for SerDes and fanouts: ~120 W→2,5 A/AMB →2,5 A *16 = 40 A 1920 W

• Wiener proposal: 3 modules 13.5 A each for a total of 40.5 A

2nd Hipothesis AUX-SSB 90 W

Update -Option B Power needed/crate ~5870 W Wiener not standard

• 5V: VME + SSB? → SSB 90 W/board tot 360 W (70 A); Wiener proposal: 1 module 115 A for a total of 575 W

• 12 V: Amchip core• AMchip core; goal~128 W→10.7 A/AMB→10.7 A *16 = 170, 7 A-2048W Wiener proposal: 4 modules @12 V 600 W each for a total of 2400 W

@12 V 50 A each for a total of 200 A (2400 W) ???

• 48 V: for SerDes and fanouts: ~120 W→2,5 A/AMB →2,5 A *16 = 40 A 1920 W-300W

• AUX card; 90 W →1,875 A/AUX→1,875 A *16 = 30 A- 1440 W • Wiener proposal: 6 modules 13.5 A each for a total of 81 A

2nd Hipothesis AUX-SSB 90 W

VME BACKPLANE NEW Proposal – end 2013

J1 J2

J0 - Vipa

2 pins on J1 (3 A max)→ 48 V : Max 3 A/board, available to AMB only; 2,5 A/Amboard needed

5V in J1, J2 and J0 → 4+3+6 pins (19,5 A max): for SSB only (97 W max); VPC pins → 3 (4,5 A max) for VME + extra support to SSB (22.5 W max);

12V in J1 → 10 pins ex 3.3 V, eventually also 1 extra pin at 12 V; They are connected together nowfor Amchip core only, 10 A * 16 =160 A in J1; For AUX allocated the J0→ 8 pins; Option A 12V: tot available current ~12 A → ~ 144 W/boardOption B 48 V: tot available current ~12 A → ~ 576 W/board max power

IF the hypothesis are NOT respected

(2 W/ 128 kpattern & 90 W/FPGA board, SSB or AUX)

We need 4 more crates and less boards/crate

UNCERTAINTIES on made IPOTHESIS1. Will AMCHIP core consumption be < 1 W /64 kpatterns ??

2. Will AUX board consumption be ~ 90 W ??

Proposal: let’s use what we have for 2015 as much as possible, let’s buy new stuff when uncertainties above are clarified.RACK will be defined at that moment.
