Specialty Logic Procurement Notes

Verify the specific ordering suffix BFG8 to ensure correct package type and tape/reel configuration. Confirm that the 1.7V to 1.9V operating voltage aligns with your system's power delivery network. Check for RoHS compliance status if required by your manufacturing standards. Ensure compatibility with SSTL_18 signaling levels in your design environment.

Specialty Logic Selection Notes

Select this component when a configurable registered buffer is required for DDR memory interfaces. The choice between 25-bit 1:1 and 14-bit 1:2 modes depends on the specific bus width and topology requirements. Ensure the PCB layout accommodates the 96-lead CABGA package dimensions. Verify that the target application supports the specified 1.8V nominal supply voltage range.
