Using a coaxial cable with the proper SMA connector, attach
the output of the converter, either IOUTA or IOUTB, to the
measurement equipment that will be evaluating the
converter’s performance. Make sure that the jumpers are in
their proper placement. Consult the ‘Voltage Reference’
section and the ‘Sleep’ section of this document for a
definition of the jumpers’ functionality. Optimum single-
ended performance is usually achieved by either grounding
or equally terminating the unused output so that its loading
matches that of the output being measured.
Learning Your Way Around
Direct Digital Synthesis
To ensure that everything on the board is configured
properly and functional, it is suggested that the following test
be performed. The board test requires:
1. HI5760 Evaluation Board.
2. Spectrum analyzer.

Connections
Note: If the HSP-EVAL Board is to be used, it is highly
recommended that the user obtain the User’s Manual, the
datasheet for the HSP45116 NCOM, and the User’s Manual for
the HSP45116-DB. This platform is capable of testing the
converter up to 25 MSPS, which is the speed of the
HSP-EVAL’s on-board clock. The user can choose to substitute
this clock with a slower one, but the DSP chip and DSP Eval
Board are only designed to work at a maximum of 25MHz (a
52MHz version of this DSP chip does exist but not in this
evaluation platform; see the HSP45116A). For testing of the
HI5760 at higher speeds, it is recommended that the user
obtain a high speed data generator capable of generating 10-bit
patterns at clock speeds up to at least 125MHz.
