Notes:
1.
To reference the DSP48A block diagram, see UG431: XtremeDSP DSP48A for Spartan-3A DSP FPGA User Guide.
2.
"Yes" means that the component is in the path. "No" means that the component is being bypassed. “–“ means that no path exists, so it is not
applicable.
3.
The numbers in this table are based on the operating conditions set forth in Table 7.
