Version 2.2
14-bit 1+GSa/s DAC Development Kit
FME/MS/DAC80S/FL_2/5488
The DK86065-2 development kit provides a simple and
DK86065-2
effective means of evaluating the MB86065 14-bit 1+GSa/s
Digital to Analog Converter (DAC).
Evaluation Platform
A user manual provides a step-by-step guide from configuring
the board and connecting test equipment, through to
evaluating performance of the MB86065. Schematics, PCB
overlays and connector pin-outs are included. The evaluation
platform requires two DC power supplies, 1.8V & 3.3V, each
capable of providing 1 amp. The PC USB programming cable
included combined with the control software available for free
download supports configuration and control of the device, as
well as downloading test vectors to the waveform memory
module.

the MB86065 is a high quality RF clock and
spectrum analyser. The phase & spurious
performance of the clock should be such as to
not limit the DAC performance (e.g. HP8664A).
However, performance of even the best
spectrum analysers available is inferior to that of
the converter. To overcome this, filtering
techniques and careful attention to analyser
settings, e.g. RF Attenuation, is essential during
the course of the evaluation.
Figure 2. Optional SMA Adaptor
Pattern generators can be connected to the
evaluation board using either the onboard 2-row
0.1" data headers, or via ribbon cables to the
optional SMA adaptors. When using the 0.1"
data headers it is assumed that a custom wiring
harness will be required. This would be made
according to the connector type and pinout of
the generators output. The optional SMA
adaptors provide a convenient conversion from
SMA to the evaluation boards 0.1" headers.
This alleviates the simultaneous removal of 28
SMAs (14-bit differential LVDS) when required
to be disconnected. One advantage of this is the
ability to easily swap the data generator
between DAC data ports if insufficient channels
are available to drive both ports simultaneously.
