Part Number: ADC32RF52
Other Parts Discussed in Thread: ADC34RF52, ADC32RF55EVM

Hi team,

Regarding the rounding process after DDC, does ADC34RF52 use convergent rounding?

Also, could you please provide BOM of ADC32RF55EVM?

As I don't have the Altium licence, I was not able to find the BOM from the design file from the thread below.

Kazuki,

This weekend was longer due to us holiday. The NCO frequency word is an integer. There is no rounding at all. It is fully up to the customer to decide how they would like to implement the NCO word programming, whether it is traditional rounding method or ceiling or floor operations.
