The Mixer IP Core performs a complex multiplication of the input sample data/timestamp AXI4−Stream (see Data Source Select) and the sine and cosine output of the NCO (see NCO). This results in a down−converted AXI4−Stream output, which is sent to the first FIR filter stage (see Stage 1 FIR Filter).
Click on AXI4-Stream Mixer IP Core - DDC Mixer for Channels 0, 1, 2, and 3 to access register information.
Refer to the Pentek Navigator AXI4−Stream Mixer IP Core Manual for a description of this IP module.
