PEX8750-AB80BI G

Analog Switches - Special Purpose Overview

The PEX8750-AB80BI G is a 48-lane, 12-port PCI Express Gen3 switch manufactured by Broadcom Limited. It features integrated 8.0 GT/s SerDes and operates within a 27 x 27mm², 676-ball FCBGA package. The device supports PCIe Base Specification r3.0 with backward compatibility to r1.0a/1.1 and r2.0. Typical power consumption is 10.3 Watts. Key performance metrics include a maximum packet latency of 150ns for cut-thru switching and support for a 2KB maximum payload size. The architecture allows flexible port configurations of x4, x8, or x16 lane widths.

Analog Switches - Special Purpose Feature Summary

• Multi-host capability supporting up to three upstream host ports with 1+1 or N+1 failover redundancy
• Non-transparent (NT) port configuration enabling dual-host systems with isolated memory domains
• Integrated visionPAK debug suite featuring per-port performance monitoring and SerDes eye capture
• Hot-plug support across all ports via I2C interface with four native hot-plug controllers

Analog Switches - Special Purpose Applications

• Host-centric fan-out in multi-processor server designs
• Multi-host systems requiring traffic isolation between multiple CPU cores
• High availability applications utilizing host failover mechanisms
• Peer-to-peer traffic patterns in storage and communications platforms

Analog Switches - Special Purpose Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package dimensions and lead-free status. Confirm lifecycle status as discontinued through authorized channels. Ensure compliance with RoHS directives and moisture sensitivity levels prior to assembly. Validate that the component matches the required 676-ball FCBGA footprint for your design.

Analog Switches - Special Purpose Selection Notes

Select this component when designing systems requiring high-bandwidth non-blocking interconnection for servers or storage. Consider its multi-host capabilities if building clustered or redundant architectures. Evaluate the 150ns latency and 2KB payload support for performance-critical workloads. Ensure the design accommodates the 27x27mm package size and thermal requirements associated with 10.3W typical power dissipation.
