89HT0808PYBAB8

Specialized Overview

The 89HT0808PYBAB8 is a PCIe retimer manufactured by Renesas Electronics, designed for signal integrity enhancement in high-speed serial links. It supports four lanes with data rates up to 8 Gbps, compliant with PCI Express 3.0 specifications. The device utilizes a 100-lead Fine-Pitch Ball Grid Array (FPBGA) package measuring 9x9 mm. Operating parameters include a supply voltage range of 2.4V to 3.6V and an industrial temperature range from -40°C to +85°C. Key electrical characteristics feature low jitter performance and integrated equalization capabilities to compensate for channel loss.

Specialized Feature Summary

• Provides active signal regeneration for four independent PCIe lanes to extend trace length limits
• Integrates adaptive equalization algorithms to mitigate high-frequency signal attenuation
• Supports configuration and status monitoring via I2C interface for system integration

Specialized Applications

• Server backplane interconnects requiring signal reconditioning
• High-performance storage subsystems utilizing SAS or SATA protocols over PCIe
• Network infrastructure equipment demanding reliable 8Gbps data transmission

Specialized Procurement Notes

Verify the exact suffix against official Renesas documentation, as variations may indicate different thermal grades or packaging options. Confirm current production status through authorized distributors, as this component family has faced discontinuation notices. Ensure compliance with RoHS directives and check for moisture sensitivity levels prior to surface mount assembly processes.

Specialized Selection Notes

Select this retimer when passive copper cables or traces exceed recommended length limitations for PCIe 3.0 signals. Evaluate power consumption requirements against available board thermal dissipation capacity. Compare pin compatibility with existing PCB layouts to ensure the 100-FPBGA footprint matches design constraints without requiring redesign.
