89H48H12G3YCHLI

Overview

The 89H48H12G3 is a 48-lane, 12-port PCI Express Gen3 system interconnect switch designed for high-performance applications. It delivers up to 96 GBps (768 Gbps) of switching capacity through integrated SerDes supporting 8.0 GT/s operation. The device features a non-blocking architecture with low latency cut-through and supports PCIe Base Specification 3.0 standards including Advanced Error Reporting and Atomic operations. Packaged in a 27mm x 27mm 676-ball FCBGA, it enables multi-root support with up to 12 independent partitions and includes SECDED ECC protection on internal RAMs.

Feature Summary

• High-performance non-blocking switch architecture optimized for multiple simultaneous peer-to-peer traffic flows
• Multi-root support allowing up to 12 fully independent switch partitions with dynamic reconfiguration capabilities
• Comprehensive reliability features including ECRC support, end-to-end data path parity, and SECDED ECC protection
• Flexible initialization options supporting Root complex, Serial EEPROM, pin strapping, or SMBus configuration

Applications

• Enterprise servers requiring high throughput and low latency interconnects
• Storage arrays and intelligent I/O systems with inter-domain communication needs
• Communications infrastructure utilizing multiple host architectures

Procurement Notes

Verify the specific ordering suffix against official Renesas or IDT documentation to confirm package type, temperature grade, and lead-free status. Confirm current product lifecycle status as this component may be obsolete or subject to last-time buy restrictions. Ensure compatibility with existing board layouts regarding the 676-ball FCBGA footprint and power requirements before procurement.

Selection Notes

Select this component when designing systems requiring extensive PCIe Gen3 bandwidth aggregation across multiple ports. Consider the 676-ball FCBGA package constraints and thermal management requirements for dense server environments. Evaluate the need for multi-root partitioning features versus simpler single-root configurations to optimize design complexity and resource utilization.

Part Context

This part belongs to the IDT 89H48H series of high-performance PCIe switches. It represents the Gen3 iteration of the 48-lane 12-port architecture, succeeding earlier Gen2 variants like the 89H48H12G2. The device is manufactured by Integrated Device Technology, which was acquired by Renesas Electronics Corporation.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify if the 89H48H12G2 serves as a backward-compatible alternative for Gen2-only designs, though performance characteristics will differ significantly.
