as physically possible. Similarly, DVDD, the digital supply, should
be decoupled to DCOM as close to the chip as physically possible.
For those applications that require a single 3.3 V supply for both
the analog and digital supplies, a clean analog supply may be
generated using the circuit shown in Figure 18. The circuit
consists of a differential LC filter with separate power supply
and return lines. Lower noise can be attained by using low ESR
type electrolytic and tantalum capacitors.

EVALUATION BOARD
General Description
The TxDAC family evaluation boards allow for easy setup and
testing of any TxDAC product in the SOIC and LFCSP
packages. Careful attention to layout and circuit design, com-
bined with a prototyping area, allows the user to evaluate the
AD9744 easily and effectively in any application where high
resolution, high speed conversion is required.
This board allows the user the flexibility to operate the AD9744
in various configurations. Possible output configurations include
transformer coupled, resistor terminated, and single and differ-
ential outputs. The digital inputs are designed to be driven from
various word generators, with the on-board option to add a
resistor network for proper load termination. Provisions are also
made to operate the AD9744 with either the internal or external
reference or to exercise the power-down feature.
