Yes, the AD9684 is equipped with four wideband digital processors. A crossbar
mux takes care of the data routing between the ADC and the DDC (Digital Down
Converters). Each of these DDCs has a 12-bit NCO (Numerically Controlled
Oscillator) that enables the customer to tune to the desired frequency. Each
DDC also has four half band filters. Please refer to the datasheet DDC section
for more information.
