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

Testing With FEC 5

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 Gbps transceivers 6

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 7

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 8

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) 9

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 10

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

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

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

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

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

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

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 17
