Problems about DAC 5674 EVM

EbuBad

Hey,

about DAC 5674 EVM, when i send data bits with 1 MHz clk speed ,16 samples, and installed just X4, not installed HP1 and HP2.

I cant see the sine wave clear, just like discrete sine wave

what is the problem ?

1 MHz clk is less ? are there any more info about DAC 5674 EVM ? its user guide is inefficient

Kind Regards.

That is the expected output of the DAC at 1 MHz clock, which corresponds to 1 us step size of sample-and-hold. You might want to provide a faster clock to reduce this step size.
