The HI5703EVAL evaluation board can be used to evaluate
the performance of the HI5746 10-bit 40 MSPS analog-todigital
converter (ADC). The HI5703EVAL evaluation board
is made electrically compliant with the HI5746 by making a
simple resistor change in the reference voltage generation
circuits allowing the former +3.25V reference generator circuit
to be adjustable to +2.5V.
As shown in the HI5703EVAL Evaluation Board (Modified)
Block Diagram, the evaluation board includes clock driver
circuitry, reference voltage generators (modified), and a
choice of analog input drive circuits. Buffered digital data
outputs are conveniently provided for easy interfacing to a
ribbon connector or logic probes. The evaluation board is
provided with some prototyping area for the addition of user
designed custom interfaces or circuits. Additionally, the
evaluation board is provided with eight removable jumpers
to allow for various operational configurations. Refer to
AN9534, “Using the HI5703 Evaluation Board”, for a complete
technical discussion on the evaluation board.
