Broaddown 4

Broaddown-4 is a high capability FPGA development board. Based on Xilinx Virtex™-4 devices it offers the ultimate platform for development of FPGA based systems in DSP, Microprocessor, ASIC and Logic Intensive designs. Based on Enterpoint’s Moel-Bryn family philosophy of offering maximum flexibility to users Broaddown4 is supported by an expanding wide range of add-on modules.

Availability

Broaddown4 is now fully available in all configurations.

FPGAs

Broaddown4 can take directly on-board 1 or 2 of the following Virtex™-4 FPGAs in any combination LX40, LX60, LX80, LX100, LX160, SX55.

Broaddown4 has 2 Moel-Bryn module positions. Moel-Bryn sockets can support further Virtex™-4 FPGAs or other specialist devices.  Further FPGAs can be fitted in DIL positions and SODIMM sockets if not used for other functions.

A Spartan-3 XC3S1500 is also available for user defined ancillary tasks including file management.

PCI-E INTERFACE

X1 PCI-E interface implemented using NXP Semiconductors PX1011A transceiver and interface logic in FPGA. Supports 2.5Gbit data transmission. (2Gbit real rate).  More details of the PX1011A here. Enterpoint now has a PCIE core available to license with this board.

DDR2 Memory

Broaddown4 supports for each FPGA fitted a DDR2 SODIMM socket with 2 Gbyte capability. These positions also have alternative uses such fitting extra FPGAs, General I/O and high performance microprocessor.

On Board DDR2

Broaddown4 now supports 1 off bank of 256Mbit-1Gbit X16 bank of DDR2 on Device1. Device2 (when fitted) supports 2 off banks of 256Mbit-1Gbit X16 bank of DDR2.

Flash Memory

High density flash memory available for code and data storage.

EEPROM

One 256Kbit serial EEPROM available for each FPGA fitted.

MMC Memory Card

Broaddown4 has 1 MMC Card slot.

DIL Headers

2 sets of DIL Headers supporting DIL components or modules.

Clocks

Broaddown4′s clock system has a sophisticated programmable clock generator structure capable of generating multiple independent frequencies up to 700MHz.

User I/O

Large number of user I/O available.

Power Management

Advanced power management features of Broaddown4 allow the measurement and control of power rails.

Encryption Key Support

Broaddown4 has battery backup to maintain bitstream encryption keys.
