Zefant-XS3 Users Manual

Settings on Zefant module

• SB1301 MUST be set if no external voltage is provided for banks 2/3
• SB1301 MUST NOT be set if an external voltage is provided for banks 2/3
• JTAG DIP-Switches C/D of SW1201 must be set according to chapter 4.7.2
• SB1401 MUST be set if you want to use JTAG port on TopDown baseboard. See 4.7.3 for more informations. In case of a module stack, this applies only to the bottom-most module.
• SB1401 MUST NOT be set on any other module than the bottom-most of stack, a short circuit between the 3.3V rails of neighbour modules would be caused.

Settings on TopDown baseboard

• SB201/SB202 MUST be set to enable the power supply of the Zefant module

"TopDown" Mounting

To mount a Zefant module with the FPGA side pointing to the baseboard, 2 FX8C-80P and 2 FX8C-100P connectors are placed on the baseboard as shown here:

"TopUp" Mounting

To mount a Zefant module with the SODIMM side pointing to the baseboard, 2 FX8C-80S and 2 FX8C-100S connectors are placed on the baseboard as shown here:
