... TM Application Note Description The HI5728EVAL1 evaluation board provides a quick and easy method for evaluating the HI5728, 125MSPS Dual High Speed DAC. Each converter outputs a current into a load resistor to form a voltage which can be measured by using the included SMA connectors. The amount of current out of the DAC is determined by an external resistor and either an internal or external reference voltage ...

Functional Description Overview The evaluation board is configured to be interfaced using a VME connector. The data input lines are tied together using small, zero ohm resistors on the back side of the board (QD0 is tied to ID0, continued ...

Differential Output The board is also configured with the following transformer output which will result in an output voltage amplitude that is twice that Req, where Req is the equivalent OUT resistive loading seen by the current ...

... The HSP45116 NCOM generates two, 16-bit channels of data. HI5728EVAL1 is designed so that both of its input channels mate with both of the DSP’s output channels. The zero ohm resistors that connect the I and Q channels together on the DAC eval board must be removed before using the HSP45116 evaluation board ...
