There is a Channel Data Source Select Core for each Digital Signal Processing channel (Ch0, Ch1, etc.). This core selects the data stream for this DSP channel from one of the ADC AXI4−Stream Merge Cores (see ADC AXI4−Stream Merge) or a Test Signal (see Test Signal Generate).
The input and output data for this core are combined sample data/timestamp AXI4−Streams.
Click on AXI4-Stream Multiplexer IP Core - Data Source Select Mux for Channels 0, 1, 2, and 3 to access register information.
Refer to the Pentek Navigator AXI4−Stream Multiplexer IP Core Manual for a description of this IP module.
