PEX8747-CA80FBC G is listed in the Analog Switches - Special Purpose range at ChipApex. The manufacturer field lists Broadcom Limited. Its product description is PEX8747-CA80FBC G. Review the specifications below when checking this part for your BOM.
The PEX8747-CA80FBC G is a Multi-Root PCIe Gen 3 switch manufactured by Broadcom Limited. It provides 48 lanes of connectivity across five ports, supporting data transfer rates up to 8.0 GT/s. The component operates within a temperature range of 0°C to +70°C and utilizes an SMD/SMT mounting style in an FCBGA-676 package. It complies with RoHS3 standards and carries an MSL rating of 3 (168 hours).
Verify the exact ordering suffix against the manufacturer's current documentation to ensure compatibility with specific board designs. Confirm that the FCBGA-676 package dimensions align with your PCB footprint requirements. Check for any recent Product Change Notices regarding adhesive materials or assembly processes before finalizing procurement plans.
Select this component when a five-port PCIe Gen 3 solution with 48 total lanes is required. Ensure the design supports the necessary power delivery for the FCBGA-676 package. Verify that the host system can accommodate the thermal output associated with high-speed switching operations at the maximum operating temperature.
This part belongs to the PEX 8747 series of ExpressLane switches. It serves as a core connectivity element for expanding PCIe topology in complex server environments. The device integrates multiple lanes into a manageable port structure for efficient data routing.
The PEX8732-CA80BC G offers 32 lanes and 8 ports but lacks the 48-lane capacity of the PEX8747. Substitution requires re-evaluating bandwidth needs and port count requirements. Pinout and package differences must be addressed during integration.
