89HT0808PZAAB

Specialized Overview

The Renesas 89HT0808PZAAB is a PCIe retimer IC belonging to the 89HT0808P series. It provides signal regeneration for high-speed serial data links, specifically supporting PCIe 3.0 specifications at data rates up to 8 Gbps per lane. The device features four independent lanes and utilizes a CABGA-100 package. It incorporates advanced equalization techniques to mitigate channel loss and jitter accumulation in demanding computing, storage, and communications applications.

Specialized Feature Summary

• Supports 4-lane PCIe 3.0 operation with 8 Gbps per channel capability
• Corrects total jitter including random (Rj) and deterministic (Dj) components via Link Equalization Procedure
• Integrates CTLE and DFE receiver equalization alongside large swing transmitter with boost, pre-shoot, and de-emphasis

Specialized Applications

• High-performance computing systems requiring signal integrity extension
• Enterprise storage subsystems utilizing SAS or SATA over PCIe bridges
• Communication infrastructure equipment needing reliable high-speed interconnects

Specialized Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure ESD protection protocols are followed during handling due to the CABGA-100 package type and sensitivity to static discharge.

Specialized Selection Notes

Select this component when designing systems requiring active signal regeneration for four PCIe 3.0 lanes. Evaluate board stack-up and trace length requirements against the retimer's equalization capabilities. Consider power consumption and thermal dissipation characteristics inherent to the CABGA-100 form factor in dense layouts.

Specialized Part Context

This part is part of the IDT/Renesas 89HT0808P family of PCIe retimers. It serves as a signal conditioning solution for extending reach beyond passive copper limitations. Related evaluation tools include the 89KTT0808P board for system-level testing and configuration via USB-to-I2C interfaces.

Specialized Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing firmware and hardware designs if considering alternative retimer solutions from other manufacturers.
