Components
Stratix II device FPGA U18 EP2S180 Stratix II device
MAX Device PLD U10 EPM7256 ETC144 device
A/D converters I/O U1, U2 Two 12-bit 125-MHz A/D converters
D/A converters I/O U14, U15 Two 14-bit 165-MHz D/A converters
1 MByte SRAM Memory U43, U44 1 MByte of 10-ns asynchronous SRAM configured as a
32-bit bus.
16 MBytes of flash
memory Memory U17 16 Mbytes of flash memory configured as an 8-bit bus.
32 MBytes of
SDRAM Memory U39, U40 32 MBytes of SDRAM memory configured as a 64-bit
bus
SMA external clock
input connectors Input J10, J11, J12 SMA connectors for inputs of external clock signals,
terminated in 50
Ω.
Dual 7-segment
display Display U12, U13 Dual 7-segment display.
Push-button
switches I/O SW4, SW5,
SW6, SW7 Four push-button switches, which are user-defined as
logic inputs.
User-defined LEDs Display D1 - D8 Eight user-defined LEDs.
Power-on LED Display LED7 LED that illuminates when power is supplied to the
board.
