EVALUATION BOARDS
The AD9858 has three different evaluation board designs. The
first design is the traditional DDS evaluation board. In this
design, the DDS is clocked and the output is taken directly from
the DAC. The analog mixer and PLL blocks are made available
for separate evaluation.

The second design is a fractional-divide loop. This evaluation
board was designed to incorporate the DDS, the phase-detector,
and the charge pump. In this application, the DDS is used in a
PLL loop. Unlike a fixed divider used in traditional PLL loops,
the output signal is divided and fed back to the phase detector
by the DDS. To do this, the output signal of the PLL loop is fed
to the DDS as REFCLK. The DDS is programmed to match the
reference input frequency. Because the DDS output frequency
can take on 2
32
potential values between 0 Hz and one half of
the PLL loop output frequency, this enables frequency
resolution on the order of 470 MHz, assuming a PLL loop
output frequency of 2 GHz.
The third design is a translation loop or offset loop. In this
design, the RF mixer is incorporated into the feedback path of
the loop. This allows direct up-conversion to the transmission
frequency.
