Front-end box architecture 217 januari 2013Antonio Pellegrino, Tom Sluijk, Wilco Vink,

Front-end box 3 ◦ 1 GBT master/power board (replaces: GOL board)  Versatile link transceiver, Master GBT  TFC signals  1 SCA for monitoring (power, temperature, etc.)  8 Optical data transmitters  4 dual transmitters versatile link OR  12-way optical transmitter, based on KK Ghan’s vcsel driver (8+4 spare)  Power supplies based on CERN SM01C DC/DC conv. ◦ 4 Actel TDC boards (replaces: OTIS boards)  2 data transmitter GBT’s  Wide bus format data transmitters  One used for clocks, BxClk TpClk, TFC,clk  Spare clocks for TDC  1 SCA  Actel re-programming via JTAG  GBT configuration  4 Threshold DAC  Temperature monitoring  Soft reset Actel  1 Actel Pro-asic A3PE1500  32 channel, 5-bits TDC  Zero suppression ◦ 8 ASDBLR boards (unchanged) 17 januari 2013Antonio Pellegrino, Tom Sluijk, Wilco Vink,

Actel TDC 4 Pro-Asic A3PE1500 (4 FPGA’s/FE-box) 32 channel 5 bits TDC ◦ Based on MHz clocks(2 edges and 90phase shifted) ◦ fixed placement (3 variants: top right bottom) Zero suppression 17 januari 2013Antonio Pellegrino, Tom Sluijk, Wilco Vink,

Two options uses identical PCB, different Actel firmware ◦ 8 Data GBT’s per FE-box  One ZS output bus per 16 channels  No bandwidth limitations  NZS full bandwidth readout possible ◦ 4 data GBT’s per FE-box  One ZS output bus per 32 channels  Bandwidth limit, lower cost Wide-bus GBT format Data GBT interface 517 januari 2013Antonio Pellegrino, Tom Sluijk, Wilco Vink,
