9.3.4.1 Operating Mode: Receiver

In receiver mode (and as shown in Figure 47), the DDC block can be configured to single- or dual-band

operation. Both DDC chains use the same decimation filter setting and the available options are discussed in the

Decimation Filters section. The decimation filter setting also directly affects the interface rate and number of

lanes of the JESD204B interface.

NOTE: Red traces show SYSREF going to the NCO blocks.
