Presentation Transcript

  1. GBT AUX board • GBT AUX board replaces Gol board • Identical mech. dimensions • 8 GBT -> data transmission Snap 12 MPO opt. Tx • Option use of 4 Dual SFP Tx • 1 GBT / GBT-SCA for TFC/ECS • Bidir SFP • Interfaces four TDC cards • 128 TDC channels @ 40MHz Tom Sluijk, Albert Zwart, Antonio Pellegrino, Wilco Vink

  2. GBT AUX proto board Tom Sluijk, Albert Zwart, Antonio Pellegrino, Wilco Vink

  3. GBT AUX proto board • First proto based on AlteraStratix IV dev kit • 4SGX230N expanded with High Speed Mezzanine Card(HSMC) • Interfaces single Actel with 16 TDC channels • GBT like data bus 20b @ 160 Mb/s • Functionality: • Real time data Analysis: histogram TDC output (long runs) • Prove Actel TDC / ZS concept • Test GBT data transmission • Histogram of TDC Zero Suppressed data • Buffer burst of consecutive TDC output in RAM • Offline analysis ZS data • Short runs, length to be defined depending on ZS and memory • Data interface to host for offline analysis (proto only) • Ethernet • Altera development board expected July  Tom Sluijk, Albert Zwart, Antonio Pellegrino, Wilco Vink

  4. GBT AUX proto board • TDC Data analysis, without GBT data TxRx • Analyze 16 channel TDC output • 20 bits @ 160 Mb/s LVDS data interface with Actel 16ch TDC • HSMC pio to interface TDC data bus Tom Sluijk, Albert Zwart, Antonio Pellegrino, Wilco Vink

  5. Actel TDC 16 readout with GBT • Expanded with GBT Tx Rx loopback in data path • HSMC with SFP • Avago SFP tranceiver(s) • Use “GBT-FPGA Firmware Starter Kit“ • Data analysis includes check of GBT data path Tom Sluijk, Albert Zwart, Antonio Pellegrino, Wilco Vink
