Upgrade of the CSC Endcap Muon Port Card and Optical Links to CSCTF

1. Upgrade of the CSC Endcap Muon Port Card and Optical Links to CSCTF Mikhail Matveev Rice University 31 October 2012

2. MPC Upgrade Requirements ■ Be able to deliver all 18 trigger primitives from the EMU peripheral crate to the upgraded Sector Processor ■ Preserve sorting capabilities of the Muon Port Card ■ Preserve 3 old 1.6Gbps optical links to the existing CSCTF

3. Upgrade Developments • Use existing Muon Port Card main board - TMB interface remains unchanged (2 LCTs per TMB @ 80MHz) - 3 “old” optical links are still available • Original design was based on Xilinx Virtex-E XCV600E FPGA • New prototype (2012) is based on Xilinx Spartan-6 FPGA - Inexpensive FPGA ($280 for the fastest speed grade chip) - 8 embedded GTP serializers - 3.2Gbps/channel data rate - Modest power consumption - SNAP12 optical transmitter

4. Spartan-6 Mezzanine • First prototype was built and successfully tested with the Sector Processor prototype SP10 in April 2012 • - SP10 receivers are based • on Virtex-6 GTX blocks • - Optical PRBS test: BER<10-13 • - Various other tests and • measurements (next slides) • Second prototype built in October • - Few schematic fixes - More reliable connector to attach the SNAP12 board new old

5. New Mezzanine

6. Old and New Mezzanines Installed

7. SERDES Latency ■ Present MPC-to-SP system at CMS: - TLK2501 Transmitter (1.6Gbps - 80MHz) ~23 ns - TLK2501 Receiver (1.6Gbps - 80MHz) ~57 ns ■ New system (prototypes): - Spartan-6 GTP Transmitter (3.2Gbps – 160MHz) ~20 ns (without Tx buffer) - Virtex-6 GTX receiver (3.2Gbps – 160MHz) ~69 ns (without Rx buffer)

8. Other Measurements ■ Successful test with 9 Trigger Motherboards in the peripheral crate ■ Three old 1.6Gbps links have been verified ■ Power consumption: - Spartan-6 FPGA ~1A Vccint (1.2V) ~0.15A Vccaux+Vcco (3.3V) ~ 0.8A GTPs (1.2V) - Three MIC69501 voltage regulators on a mezzanine board passed irradiation test at TAMU in 2011 - MPC (main board + Spartan-6 mezzanine) <4A @ 3.3V

9. Production Cost Estimate ● Will need 80 mezzanines ($132,800)

10. Optical Fibers: 2 Options (1) Trunk cable with 4 or 8 connectorized cords (similar to one proposed for the DT upgrade). Each cord has 12 fibers. Will need 36 cables for 60 peripheral crates, one spare cord per crate. (2) New single fibers blown inside the spare conduits of the existing installation. 144 patch cords with MPO connectors. discussion with the CERN Electrical Engineering group is underway; expect to converge by the end of 2012

11. MPC Upgrade Plans ■ Proceed with the Spartan-6 pre-production prototype design - equip 3 Muon Port Cards with new mezzanines and test by December 2012 - integration tests with the uTCA SP board: January-May 2013 - irradiation test: spring 2013 - proceed with another prototype if needed: June-August 2013 ■ Production, Installation and Commissioning - buy parts, fabricate PCBs: 1 November 2013 – 31 December 2013 - assemble 80 mezzanine boards: 1-31 January 2014 - tests boards at Rice (1 board/day): 1 February – 30 April 2014 - ship to CERN: May 2014 - install at CMS: 1 June – 31 July 2014 - commissioning with the peripheral electronics and TF: 1 August – 30 October 2014
