The TX formatter block includes a per-channel TX gain adjust via a 16-bit complex digital word which can be set
to have gain between ââ and 9 dB.
Digital Down- and Upconverters (DDUCs)
The GC533x has four identical and independent DDUC blocks that can be configured as either DDC or DUC.
Each DDUC can support up to 12 channels with scalable bandwidth.
The only difference between the DUC and DDC configurations is the interpolate (DUC) versus decimate (DDC)
functions and the data path direction as shown in Figure 12. Both DDC and DUC are described in this section.
Note that each DDUC block must be configured statically as a DUC or DDC and cannot switch modes
dynamically in TDD applications.
