Digital Inputs
The digital inputs are expecting 3V CMOS levels. The board
is shipped without termination resistors so that most systems
can drive the load. The board is configured so that the user
can populate 50 ? termination resistors if required (R1-15).
Consult the datasheet for the DAC for min/max amplitude
requirements for the clock and data.
Analog Outputs
The transformer configuration is such that it expects to see a
50 ? load at the end of an RF cable. If the user wishes to
evaluate the single-ended performance of the DAC, J6
and/or J7 will need to be populated, and R31/32 should be
populated with 50 ? resistors (or a resistor of choice that
does not cause the analog output to violate the output
voltage compliance range specified in the datasheet.)
Board Schematics/Layout/BOM
The schematics, board plots, and bill of materials can be
downloaded from the Intersil web site. Search on the DAC
part number.
Other
The labels on the board for IOUTB (J8) and IOUTA (J9) are
backwards. J8 should be IOUTA and J9 should be IOUTB.
ISL5x61 + ISL5217 Combo
The ISL5x61 evaluation board is designed to interface
directly to an ISL5217 evaluation board. The ISL5217 is a
104MSPS Digital Up Converter. The ISL5217 can be used to
