DEARS.

I am reviewing ADC32RF80 design.
REAL is input
See Table 19 of the datasheet.
DECIMATION Column 1, line 2 is different.
What should REAL be set to?

It Is COMPLEX UNCHECK in the GUI a REAL setting?

Thank you

Henry,

To use real data, you would uncheck the Complex box either in the DDC block of the quick start tab or DDC Configuration tab under the ADC32RFxx tab. For line 2, in real mode, the device will use a divide by 4 decimation filter. If complex mode was select, the bandwidth would be double so the divider would be 8 for this mode.

Regards,

Jim
