1.3 Configuration FPGA:
The configuration FPGA (Xilinx Virtex 4 LX 40)
For special configuration requirements, an expansion header is connected to the configuration
FPGA. Connectivity to this header requires upgrading the configuration FPGA to an LX80.
2 Multi-Gigabit Serial Options
2.1 Serial Clock Crystals
The DN8000K10 is equipped with frequency synthesizers (ICS84321) for its high-speed serial
(MGT) interfaces. These synthesizers are appropriate for serial transmission speeds of up to
10Gbs. By default, the crystals supplied are 25.0000Mhz (MGT left or right columns) and
25.50000Mhz (MGT left column only)
These selections are suitable to meet most common serial protocols that are supported by Xilinx
MGTs and the DN8000K10. If you have specific MGT requirements, be sure to contact Dini
Group about your needs before placing your order.
Dini Group keeps the following crystals in stock for MGTs:
9.8304Mhz, 12.890Mhz, 14.318Mhz, 16.00Mhz, 21.477Mhz, 24.576Mhz, 25.00Mhz
The default option is 25.000 MHz.
3 Optional Equipment
3.1 Rack mount Chassis
The DN8000K10 is shipped on a steel base plate “carrier” to provide protection, stability and an
easy way to transport the board. Optionally, the DN8000K10 can ship inside a 4U rack mount
chassis. This carrier can be used externally to the chassis, as well as mounted inside the chassis.
The carrier allows the assembly to rest either FPGA-side up or FPGA-side down. The steel
base plate provides strain relief for daughter card insertion and removal, and provides a heatsinking path for the motherboard.
The chassis front panel provides an LCD display, a remote power switch, a configuration reset
switch, a logic reset switch, a remote Compact Flash drive, and cooling fans. Apertures with
cover plates are used to provide access for daughter card cables.
