  4. MM TPC Card (BNL) using 2x LEGS TPC ASIC’s

  5. Testing With FEC

  6. Features • Connections to two BNL front-end cards via 2x80 pin ribbon cables • 8 LVDS inputs to C-Card • 16 LVDS I/O ports • Connection to FEC card via card edge connectors • 4 LVDS inputs to C-Card • 21 LVDS outputs • 3 LVDS clocks to C-Card • 2 3.125 Gbps transceivers

  7. Features • 10/100 Ethernet and USB connections • 4 12 bit ADC’s • 4 16 bit DAC’s • 2 calibration pulse generators • 2 ramp generators • 2 FPGA clock regions from on-board oscillators or FEC

  8. C-Card Status • A C-Card has been developed for use with the LEGS TPC and VMM1 versions of the BNL peak-finding ASIC • Readout of the C-Card through the FEC Card and MAMMA DAQ program has been successfully tested • Communication with BNL MM TPC card (carrying 2 x LEGS TPC ASIC’s) has been established along with calibration signal and ramp

  9. C-Card Work List • Still longer than desired • Commission ADC section • Verify (by local readout) calibration is working • Compare C-Card ramp and MM TPC ramp • Add monitoring and data storage to MAMMA DAQ (with help from Marcin)

  10. MMFE Card • Initially, design front-end card for full size MM using BNL VMM1 ASIC • Now, re-trench and design for fastest to market product • Need to specify by yesterday • Connector type (which MM?) • Motherboard/daughter card (Mini) versus integrated card (Melded) • Input protection (NUP4114?) • Still lacking some specification of VMM1

  11. Full-size MMFE • 4 x 2 x 64 channels –on hold

  12. AIC (Analog Interface Card) • Schematic started – on hold

  13. AIC (Analog Interface Card) • Schematic started – on hold

  14. AIC (Analog Interface Card) • Layout started – on hold

  15. Going Forward • MMFE – mini • Pro - take advantage of AIC work • Con - two cards slows pace

  16. Going Forward • MMFE – melded • Pro - one card • Con - other groups could use AIC if desired

  17. Conclusions • Good progress on commissioning C-Card but additional work remains before go-to-market • Desire to converge on reduced scope MMFE card so design and layout can proceed
