Hello,
We are currently evaluating GC5330 as digital down converter , for our application we need to down sample 40 Narrow band channels (decimation rate : 108).
datasheet says GC5330 supports 48 Narrow band channels if we use all 4 DDUC blocks in either DUC or DDC mode and with each DDUC block having 3 ( Mixer / NCO's).
With the total no of mixers being 12 (in 4 DDUC blocks), is it only support 12 independent channels to configure with 12 different NCO's ?
In our case IF (intermediate frequency) of 40 narrow band channels are different but with common decimation rate of 108.
IS it possible to use GC5330/GC6016 for our application ..kindly suggest
