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

Upgrade Developments n Use existing Muon Port Card main board - TMB interface remains unchanged (2 LCTs per TMB @ 80MHz) - 3 “old” optical links are still available n Original design (2004) was based on Xilinx Virtex-E XCV600E FPGA

n New prototype (2012) is based on Xilinx Spartan-6 FPGA - Inexpensive FPGA ($280 for the fastest speed grade XC6SLX150T-3FG900C device) - 8 embedded GTP serializers - 3.2Gbps/channel data rate - Modest power consumption

(~1A Vccint; <1A GTPs)

- Pluggable 12-channel

optical transmitter

n Three MPC main boards are equipped with new mezzanines (Rice, UF, bld.904 – test stand for ME2/1)

Optical Transmitter

n SNAP12 and Avago AFBR-810 are pluggable 12-channel devicesn Both use the same 10x10 low profile circuit, but pin assignment is different (Avago is intended for higher data rate, needs 3.3V and

2.5V power)■ uTCA MTF6 uses Avago AFBR-820 receiver, so the Avago AFBR-810

transmitter is our primary choice

Optical Tests at Rice, 2012-2013n Three MPC boards with the new mezzanines

n SP10 prototype

n Test software is available, various PRBS and random

patterns

n Random patterns from MPC FIFO to SP10 FIFO under

slow VME control: 10K iterations (510 frames each);

no errors, all boards

n PRBS tests OK, BER<10-13

Measurements

■ Power consumption: - Spartan-6 FPGA ~1A Vccint (1.2V) ~0.15A Vccaux+Vcco (3.3V) ~ 0.8A GTPs (1.2V) - MPC (main board + Spartan-6 mezzanine) <4A @ 3.3V

■ Latency:

Optical Fibers for P.5

● Trunk cable with 4 connectorized cords (similar to one proposed for the DT upgrade). Each cord has 12 fibers. Need 36 cables for 60 peripheral crates, one spare cord per crate.

● Cable sample was successfully tested at UF in April 2013 ● Purchase order ($81.3K CHF) has been placed through CERN in April 2013, expected delivery in October 2013. Will be checked by CERN experts. Installation by a CERN team.

Irradiation Tests, April 2013

■ EPROM was tested at TAMU cyclotron - Irradiated with 1 MeV equivalent fluence at ~10.5*1012 equivalent to ~30kRad, or 30 years of LHC exposure in ME1/1 area - Device was read back; not a single bit change, as expected■ Spartan-6 was irradiated at the UC Davis cyclotron - Cross section of SEU = 2.5x10-9 cm2 , or 1 SEU in ~ 55 hours per device - Irradiated with ~100 kRad at a rate of 360 Rad/sec; the device survived and was functional

New MPC-to-SP Data Format

■ Proposal from Lev Uvarov, June 2013: - Preserve existing LCT format for all CSCs- Put CSCs 2-9 into fibers 1-8- Split CSC 1 between fibers 1-8; 7 bits per each fiber

■ This idea has been recently implemented in the MPC firmware and tested internally (FIFO-to-FIFO transmission)

How to squeeze 18 LCTs from 9 CSCs into 8 fibers at 3.2Gbps?

Preparations for Mass Production

■ Purchased 3 samples of optical pigtail from CERN. Ordered 80 more. ■ Purchased 80 optical couplers to be installed on the front panels■ Fabricated 80 new front panels ■ Minor layout change in the optical transmitter board has been done. PCBs are being fabricated.■ Need 2...3 minor changes in the mezzanine design■ Ordered critical parts for 80 boards (optical transmitters, FPGA). Estimated delivery is mid November.

MPC Near Future Plans

■ Need to set up a test stand at Rice: Track Finder VME crate (exists) - MPC, SP05, CCB, TTCvi/vx (all exist) New uTCA crate (exists) - controller, AMC13 card, MTF6 Software to run uTCA■ Will need similar test stand in bld.904 at CERN by summer 2014

Muon Sorter Upgrade

■ Upgraded mezzanine board with Virtex-5 XC5VLX110T-2FF1136C FPGA - Fully compatible with the existing main board (3.3V logic levels, 640 I/O) - 16 embedded GTP links, up to 3.75Gbps data rate - One muon fits one GTP link at 3.2Gbps■ Optical transmitter to the interim calorimeter trigger (4 muons) - Optical standard (SNAP12, QSFP, Avago AFBR-820/810…)? - Data rate and format? - Any other optical links (uTCA GMT…)?■ Schedule and tests (when and where?)
