  1. Work Review Angel Monera Martinez

  2. Index • Objectives • Time Frame • Analog Link • Analog Requirements • Miteq Characterization and tests • Digital Link • Requirements • Laser and photodiode Tests and results • The prototypes (test and results) • Software Developed • Test Beam & Link Validation • Pricing • Review and Conclusions • Bibliography • Acknowledgments • Request and questions

  3. Objectives • Develop an Analog Optical Link for the AB/RF Group • Develop a Digital Optical Link • Develop the links and leave them ready for the test beam • Help to install the links and crates in the PCR and experiments

  4. Timeframe Forecast Definitive Version Definitive Version Timeframe Followed Timeframe Blue: Analog Link Green: Digital Link Yellow: AB/RF Validation or test

  5. Analog Link (Requirements) • Use the AB/RF Miteq Lasers/Photodiodes • Capability of Monitoring Photodiode and Laser • Pluggable in standard crates/racks  VME interface • Heat Sink required • Firmware development in Visual Elite… • … Using the VME code provided by AB/RF

  6. Analog Link (Miteq Characterization) • Tests done in collaboration with AB/RF Group… • …Over two test board with temperature sensors • Tests: • Temperature Vs Gain tests were developed in a climatic chamber • Bandwidth • Phase noise @400, 40 and 10 (MHz)

  7. Analog Link (Test's Results) • From Temperature test were known: • Heat sink + air flow •  Ideal conditions @ 25-30Deg (~8dB gain) • Air flow or heat sink •  extreme work conditions@40-50Deg (~1dB lost@) • No heat sink / No airflow •  Laser and photodiode break down >60Deg • From bandwidth test were known: • Bandwidth from 30KHz to 3GHz • There is an Internal AGC • The output signal is inverted.

  8. Analog Link (Test's Results) • From Phase Noise tests were obtained: • (Table) • Low noise but higher than the old Miteq used • Noise contain high 50Hz Component. (eliminating this component the noise values are reduced around 50%)

  9. Analog Link (The Prototype Boards)

  10. Digital Link (Requirements) • Same architecture as Analog • Same or close to analog performance • Increase monitoring capability • Frequency Detection • Power Monitoring & Signal detection • Laser Enable / Disable • No Heat Sink • Firmware development in Visual Elite… • … Using the VME code provided by AB/RF

  11. Digital Link (Lasers) • 3 Digital Lasers were tested (and compared with the analog) • OCP STX 03 (155MHz) • OCP STX 24 (1.2GHz) • PHOTON MT5 343 ( obsolete 155MHz ) • As Results: • OCP 24 Better skew and s2s from low freq. to 40MHz • OCP 03 Better for skew@400MHz (out of range)

  12. Digital Link (Photodiodes) • Digital photodiode were tested • OCP SRX 03 (155MHz) • OCP SRX 24 (1.2GHz) • TRUELIGHT TRR (155MHz) • OKI OF363B-C3 • LDI LPA 1000PT-D & LDI LPA 1000PT-D v2 • JDSU EDR515D • As Results: • OCP 24: Better for 400 and 10 MHz • Truelight: Better for 40MHz and pulse reception

  13. Digital Link (Prototype Boards)

  14. Software • A few interface were written to control The boards: • VME Monitor for Windows and Linux in C/C++ • Read Monitor (Tcl/Tk): Generic Reader • Write Monitor (Tcl/Tk): Generic Writer • ReadRXD: Control Rx_D board • ReadTXD: Control Tx_D board • ReadRFA: Control RF_RX/TX_A boards • Scan: Detect the RF boards in a crate

  15. Software (Screenshots)

  16. Test Beam and Link Validation • Link tested in lab: Digital and analog links works in similar way and better than the old TTC system • In the Test Beam (Sep 2006), in a real scenario, the Analog works more stably than the digital and the old TTC system (TTCRD12 & TTCmi)

  17. Pricing • The Digital Link is 4 times cheaper than the Analog link

  18. Review - Conclusions • All the prototype boards and software developed are working and have been validated by the ESS/TTC and by the AB/RF group • The digital boards need some changes that will improve their performance (changes that will be done for production)

  19. Acknowledgments • Too many people to say thanks.. Specially to: • Sophie Baron to help me in the project and choose me between the “thousands” of applications… • Christopher Parkman and Mike Clayton: to let me work in their group and “tolerate” my network problems • AB/RF group in specially to Philippe Baudrenghien to show me the Analog side of the things • And to all the ESS Group to accept me like one more in the group

  20. Bibliography (Docs Writen) • Boards user manuals • 3 User manuals were written • RF_A (RF_RX/TX_A boards) • RF_RX_D Board • RF_TX_D Board • Programming user manual • 5 Software manual were written • Generic Readers • Specific TCL/TK applications for each board • Lasers and photodiode evaluation report • Publication with Sophie Baron in the book of the workshop’s conference
