89HT0808PYDABG8

Specialized Overview

The 89HT0808PYDABG8 is a PCIe Retimer IC manufactured by Renesas Electronics Corporation. It supports four lanes with a data rate of 8 Gbps, compliant with the PCI Express 3.0 specification. The device is housed in a 144-ball Ball Grid Array (BGA) package. It is designed to regenerate and retiming high-speed serial signals to extend transmission distances and maintain signal integrity in demanding computing, storage, and communications applications.

Specialized Feature Summary

• Provides signal regeneration for four independent PCIe 3.0 lanes operating at 8 Gbps per lane.
• Integrates advanced digital processing capabilities to correct total jitter components.
• Features automatic link equalization procedures to optimize operating parameters dynamically.

Specialized Applications

• High-performance server systems requiring extended PCIe trace lengths
• Storage area network infrastructure equipment
• Enterprise networking hardware utilizing PCIe interconnects

Specialized Procurement Notes

Verify the specific suffix 'PYDABG8' against official Renesas documentation to confirm exact package dimensions and thermal characteristics. Ensure compatibility with existing system designs before procurement, as this component may be subject to discontinuation notices or lifecycle changes.

Specialized Selection Notes

Select this component when designing systems that require retiming for four-lane PCIe 3.0 interfaces at 8 Gbps. Consider the BGA package constraints and thermal management requirements associated with high-density signal conditioning circuits in server or storage environments.

Specialized Part Context

This part belongs to the 89HT08xxP series of PCIe Retimers from Renesas. Similar models include the 89HT0832P, which offers sixteen lanes, and the 89KTT0808P, an earlier variant. These devices are engineered to address signal degradation issues in high-speed serial communication links within modern electronic systems.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers for the 89HT0808PYDABG8 were not identified in available sources. Verify functional equivalence with other 4-lane 8Gbps PCIe retimers if direct replacement is required.
