Low-Pass/Low-Pass 4
y Interpolation Filter Operation
Figure 16 shows the low-pass/low-pass interpolation operation where the 4
× FIR filter is implemented as a
cascade of two 2
× interpolation filters with the input signal coming from a digital signal source such as an FPGA
or digital upconverter (DUC). Users can place their IF signal at a maximum of 0.4 times the FIR filter input (i.e.,
DAC5674 input) data rate. For a 100-MSPS data rate, this would translate into a pass band extending to 40
MHz.
