Input characteristics reminder
Input characteristics (reminder)

  • VME 32 6U

  • 2 independent input channels (ROS8)

  • Deserializer (Texas Inst. TLK 1501) with input from:

    • Optical receiver (Stratos Lightwave M2R-25-9-1-TL)

    • Copper serial link (can’t be used for Magnet Test)

  • Input FIFO 16 bit x 8k

  • Access to FIFO from deserializer or VME (debug)

Output characteristics reminder
Output characteristics(reminder)

  • Output FIFO 32 (64) bit x 2k

  • FIFO readable via:

    • VME, 32 bit words (25 MB/s)

    • s-link 64 (132 MB/s with 32 bit words)

  • Format of data: carbon copy of data received from ROS8

  • Header and trailer added

Status
Status

  • Standalone tests in Torino:

    • Fully tested and OK with VME

    • Fully tested and OK S-Link output

  • Test in Madrid

    • Tested and OK with 2 channels input from ROS-8 in Madrid and VME output

  • Test in Legnaro

    • Tested with 2 channels input from ROS-8 in VME and S-Link output (work in progress)

Needed for magnet test
Needed for magnet test

  • Total number of boards (4 available now) and optical receivers (to buy now)

  • LVDS external CLK (from TTC)

  • VME CPU for local access (Status and Control registers, configurations, local data readout)

  • S-link readout hardware (transmitter)

  • More tests in Legnaro if ROS-8 will be used OR

  • tests in Madrid if final ROS will be used
