IC7 is a
to the FPGA’s VCCINT supply input, 2.5V to the FPGA’s VCCAUX supply input, and 3.3V
to other components on the board and to the FPGA’s VCCO supply inputs on I/O Banks 0,
1, and 2.
Jumpers JP6 and JP7 provide a means to measure current across the FPGA’s VCCAUX and
VCCINT supplies respectively.
IC8 is a Linear Technology LT3412 regulator, providing 2.5V to the on-board DDR SDRAM.
Resistors R65 and R67 create a voltage divider to create the termination voltage required
for the DDR SDRAM interface.
IC9 is a 1.8V supply to the Embedded USB download/debug circuit and to the CPLD’s
VCCINT supply input.
