NONBURST MODE DATAPATH

Figure 80 shows the signal processing configuration in the

nonburst mode datapath. The input data can be direct from the

ADC or via the output of the CIC filter. The datapath uses

multiplexers configurable by the DP_CTRL register

(Register 0x116) to appropriately route the data. The

multiplexer control bits are shown in Figure 80.

•

The NO_DDC_MODE bit (Register 0x0116, Bit 1) of the

DP_CTRL register bypasses the NCO/mixer where

frequency translation is not required.

•

The BURST_MODE bit (Register 0x0116, Bit 2]) of the

DP_CTRL register) selects the decimate by J filter block.
