8430S10BYI-03LFT

Specialized ICS Overview

The Renesas 8430S10BYI-03LFT is a specialized clock generator integrated circuit designed for Cavium processors. It features two inputs and ten outputs, supporting input frequencies from 25 MHz to 167 MHz via crystal, CML, LVCMOS, LVDS, or LVPECL interfaces. The device generates multiple output frequencies ranging from 25 MHz to 133.333 MHz with LVCMOS, LVDS, and LVPECL output types. Operating on a single 3.3V core voltage, it complies with PCI/PCI-X jitter standards. The component is housed in a 48-TQFP exposed pad package (7x7 mm) with a 0.5 mm pitch, suitable for surface mount applications.

Specialized ICS Feature Summary

• Dual input configuration supporting Crystal, CML, LVCMOS, LVDS, and LVPECL signals
• Ten output channels providing LVCMOS, LVDS, and LVPECL logic levels
• PCI/PCI-X compliant jitter performance for reliable data transmission
• Single 3.3V power supply operation

Specialized ICS Applications

• Cavium processor clock generation systems
• PCI/PCI-X bus interface timing
• High-speed digital communication equipment

Specialized ICS Procurement Notes

Verify the specific suffix -03LFT against official Renesas documentation to confirm lead-free status and tape & reel packaging specifications. Ensure the 48-TQFP footprint matches the target PCB design, noting the exposed pad requirement for thermal management and grounding. Cross-reference the exact frequency programming options required for the Cavium application before finalizing procurement.

Specialized ICS Selection Notes

Select this component when designing for Cavium processor architectures requiring precise clock distribution. The choice depends on the need for mixed-signal outputs (LVCMOS/LVDS/LVPECL) and strict jitter compliance. Verify that the 25-167 MHz input range aligns with the available reference clocks and that the 3.3V supply voltage matches the system power rails.

Specialized ICS Part Context

This part belongs to the Renesas 8430 series of clock generators, which are optimized for networking and telecommunications applications. These devices typically integrate PLLs to generate stable clock signals from a single reference, reducing component count compared to discrete solutions. The 8430 series is widely used in high-performance switching and routing platforms.

Specialized ICS Replacement Considerations

Check for direct pin-to-pin replacements within the 8430 family, such as the 8430S10B variants. Verify that any substitute maintains the same 48-TQFP package dimensions and electrical characteristics, particularly the output drive strength and jitter performance metrics.
