ADC32RF42: Is each channel a quad or dual ADC?

Art Mecina
Genius 16585 points
Part Number: ADC32RF42
Other Parts Discussed in Thread: ADC32RF44, ADC32RF45

Hello Guys,

Good day.

Kindly help to clarify. The datasheet indicates each channel has 4 cores (or is interleaved across 4 ADCs), but then in other places discusses 2 cores (ie interleaved across 2 ADCs per channel). What does each channel actually have? 2 or 4 ADC interleaving?

Thanks in advance!

    Hi Art,

    Each ADC channel of ADC32RF42 is interleaved across 2 cores. Each ADC core can run at a maximum rate of 0.75 GSPS. So interleaving-by-2 makes each channel run at 1.5 GSPS in ADC32RF42. 

    Other parts from the same ADC family like ADC32RF45 and ADC32RF44 use interleaving-by-4 to achieve sampling rate up to 3 GSPS on each channel. Some parts of datasheet are copied from ADC32RF45 datasheet and not updated for ADC32RF42. 

    Regards,

    Vijay
