Anode Front End Card (1)

Adapted to the CSC plane type 5P We have had some problem with the first design New PCB Design almost completed.

Major modifications: Shielding – cross talk – lines length equalization

Ready to produce the prototype next week. Components procurement completed. Pcb production need 2 weeks Components loading 1 week Ready to mount on the CSC-5P, end of October

Mezzanines firmware

VFAT verilog code have been synthesized, routed and placed in the FPGA designed for the mezzanines (Xilinx Spartan 3.)

Need to link the physical pin out of the device with the code.

Need to write the USB driver: Probably we can adopt the driver written for the FED

mezzanine? We can “play” with the firmware, soon. Need to get the new VFAT datasheet, in particular I2C

registers mapping.
