Configuration Options
The PFC can be mounted with the following options
-
FPGA-configured-through-SPI-Flash-or-through-the-GN4124-SPRI-interface
-
Oscillators-can-be-chosen-between-Rakon-VT3205CR-or-Mercury-VM53S3
-
Power-supplies-switching-frequency-spread-spectrum-modulated-or-fixed
-
FMC-I2C-Bus-can-be-controlled-either-by-FPGA,-GN4124-I2C-bus-or-GN4124-GPIOs
Aditionally there is a switch that allows the user to access the JTAG chain through a connector or through GPIOs on the GN4124
PFC executions
The PFC will be presented with different configurations:
Standard-PFC
Negative power supplies not mounted and variable VADJ
Standard-Negative-PFC
Negative power supplies and variable VADJ.
Reduced-PFC
This configuration will not be executed. It is pointed here just as a reference. It would not mount the negative power supplies and VADJ will be fixed to 2V5.
