• DAC development kit input data adaptor
• For DK86064-2 or DK86065-2
• Provides direct connection to HiTech
Global FPGA platform
• When combined with HiTech Global FPGA
development platform:
• LVDS data interface for one (‘065) or
two (‘064) DAC cores
• Loop Clock system for optimum timing

Description
The DKXC5VADAPT-
1 DAC DK adaptor
provides a quick and effective
way to
demonstrate
a high speed data interface to the
Fujitsu DK86064 and DK86065 high perform
ance
DAC development kits. The adaptor directly
connects the DKs to the HiTech Global V5-
PCIE2 FPGA platform.
The HiTech Global FPGA
board uses the Xilinx Virtex™-5 device.
Additional headers support data input and output
to the FPGA, as well as power an
for the DAC.

System Overview
The most popular device for interfacing to
high-speed data converters is an FPGA.
FPGAs provide a relatively low-cost platform
for high-speed logic, data processing, digital
data interfaces and clock management. The
DKXC5VADAPT-1 adaptor demonstrates how
simple it is to implement a high-performance
interface between an FPGA and the Fujitsu
DK8606x DAC DKs.
The adaptor is designed to interface directly to
the HiTech Global V5-PCIE2 FPGA prototype
board to combine the power of the Xilinx
Virtex-5 with the high-speed Fujitsu DAC.
System Setup
The DKXC5VADAPT-1 provides a physical
link between the data headers on the
DK86064/65-2 and the HiTech Global V5-
PCIE2. The underside of the adaptor features
6 Samtec sockets that plug directly into the
headers on the two boards.
Adaptor underside view
The board connects 28 LVDS data pairs, the
DAC loop clock pairs and two divided clock
signals between the two boards. All clock
signals are routed to dedicated global clock
inputs on the FPGA.
The complete system forms a compact
solution ideal for testing and developing an
FPGA-DAC interface.

DAC Interface
All data and clock lines between the DAC and
FPGA are matched LVDS pairs. The adaptor
can be used with both the DK86064-2 and
DK86065-2.
Maintaining valid clock-to-data timing can
prove to be a difficult task when using high-
speed data converters. The MB86064/65
DACs avoid potential problems through the
provision of a Loop Clock system.
The Loop Clock is generated in sync with the
DAC data at the FPGA output. This clock is
passed through a user programmable delay in
the DAC and then routed back to the FPGA’s
PLL feedback input. Altering the delays in the
divided clock or Loop Clock signals allows the
user to advance or retard data timings in order
to find the optimum data eye. Once calibrated,
the system automatically compensates for the
effects of device-to-device variations, voltage
and temperature (PVT).

V5-PCIE2 Features
In addition to providing a high-speed interface
to the DAC, the V5-PCIE2 development
platform has a number of other features.
These include:
• Tri-mode Ethernet (10/100/1000)
• 4-lane PCI Express End-Point
connector (upstream)
• DDR2 SO-DIMM socket (up to 4GB)
• 512Mb DDR3 component
• 128Mb Platform Flash XL for
configuration and user flash
• On board clocking
The board is available directly from HiTech
Global with a number of different Virtex 5
parts, including the XC5VLX50T and the
XC5VFX100T.
The FPGA can either be programmed directly
over JTAG or via the on-board 128Mb flash.
The configuration can be saved into flash,
thereby removing the need to reprogram the
device at power on. Programming is
performed via a Xilinx USB programming
cable.
Adaptor Additional Features
The adaptor has a number of other features.
• Voltage regulators to provide the DAC
supply voltages (1.8V and 3.3V) using
the 5V supply for the V5-PCIE2 board.
This allows the entire system to be
powered from just one power supply
• GPIO header to FPGA
• Socket to allow connection to DK
serial programming header, thereby
removing requirement for external
serial programmer to program DAC
DK programming and power from adaptor
Sample Software
To help get started with the system Fujitsu are
pleased to offer a sample implementation for
the FPGA interface. Please contact Fujitsu
