  1. CMS LHC strip readout system APVMUX CMS FED (9U VME) APV analog opto-hybrid ~100m lasers inner barrel sensor 96 12 laser driver PA • readout hardware shopping list – for 8 sensors (4 XY planes) • 8 CMS hybrids (6 chips version) • 8 analogue opto-hybrids • optical stuff (need to discuss details with expert) • laser fibres -> 12 way ribbons -> long dist. cables -> FED • need 24 fibres altogether – 2 x 12 way ribbons • 1 FED • 1 TTCvi – provides electrical TTC signals • 1 TTCex – provides electro-optical conversion • 1 crate controller • control hardware • assume providing electrically • i.e. without CCU, etc.. • SeqSi (40 MHz/L1) • 2 x VI2C (4 chans / board) • trigger logic + power supplies, crates (1 or 2), cables, connectors, ….

  2. XY plane box (light tight) 250 mm 250 mm ~50 mm baseplate (dimensions not critical) adjustable feet for levelling

  3. XY plane box (light tight) RS diecast box (sides not at right angles to base) 250 mm ~100 mm 250 mm ~100 mm vertical piece to mount box on baseplate (dimensions not critical) method of fixing vertical piece to baseplate not shown adjustable feet for levelling

  4. XY plane XY plane XY plane XY plane few 10’s m ~ m ~ m • I2C: 1 bus per plane • actively split inside plane module • also opto-isolated • Ck/T1: 1 shielded pair per plane • CK/T1 combination at VME end • (separate module) • 1 fibre ribbon (50% utilised) per plane VI2C SeqSi TTCex TTCvi crate controller 9U/6U VME FED

  6. power I2C, RST Ck/T1 HT 1 I2C bus comes in split into 3 (2 modules + Peltier) and also generate reset Ck/T1 comes in as combined signal but needs to be recovered and buffered as LVDS will need Peltier control circuitry AOH

  8. Optical rail system up to 2 m 50 mm 80 mm X48 system from www.newport.com assume this will sit on stable table (provided by someone else) feet allow some adjustment for levelling will still need some other mechanism for overall height
