89HT0808PYDAB8

Specialized Overview

The 89HT0808PYDAB8 is a specialized interface integrated circuit manufactured by Renesas Electronics Corporation, functioning as an eight-channel signal retimer. It supports PCIe Gen3 data rates with a maximum speed of 8 Gbps per channel. The device is housed in a 100-lead Fine-Pitch Ball Grid Array (FPBGA) package measuring 9x9 mm. Designed for high-performance computing environments, it ensures signal integrity across complex interconnects.

Specialized Feature Summary

• Provides eight independent channels for simultaneous signal reconditioning
• Supports high-speed serial data transmission up to 8 Gbps
• Integrates I2C interface for configuration and status monitoring

Specialized Applications

• PCI Express Gen3 server backplanes
• High-density storage expansion cards
• Enterprise networking equipment requiring signal extension

Specialized Procurement Notes

This component is officially classified as obsolete and is no longer manufactured by Renesas Electronics. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors. Buyers must confirm the specific suffix variant matches their design requirements, as functional differences may exist between package types. Due to discontinuation, long-term supply availability is not guaranteed.

Specialized Selection Notes

Engineers selecting this part must account for its obsolete status when designing new systems. Alternative solutions should be evaluated for compatibility with PCIe Gen3 standards and similar pin configurations. Designers should verify that the 100-FPBGA footprint aligns with existing PCB layouts and thermal management strategies before finalizing component choices.

Specialized Part Context

The 89HT0808PYDAB8 belongs to Renesas's specialized interface IC family focused on signal integrity solutions. It complements other retimer products like the 89KTT0808P series, which offer evaluation boards for testing four-lane variants. This specific model provides higher channel density for demanding multi-lane applications.

Specialized Replacement Considerations

Renesas has designated the 89HT0808PYBABG8 as an alternative package type within the same product line. Users should consult official cross-reference documentation to ensure electrical and mechanical compatibility before substituting components.
