8430S07AKILF

Overview

The IDT 8430S07AKILF is a programmable clock generator featuring an integrated Phase-Locked Loop (PLL). Designed for Cavium processors, DDR memory, and PCI interfaces, it accepts diverse input signals including HCSL, LVCMOS, LVDS, LVHSTL, LVPECL, LVTTL, SSTL, and crystal sources. The device provides differential outputs in LVCMOS, LVPECL, or LVTTL formats with a fixed frequency ratio of 2:07. It operates within a supply voltage range of 3.135V to 3.465V and supports maximum frequencies up to 133.33MHz. The component is housed in a 32-VFQFPN package with exposed pads, suitable for surface mount applications across temperatures from -40°C to 85°C.

Feature Summary

• Integrated PLL for precise clock generation
• Multi-standard input compatibility (HCSL, LVCMOS, LVDS, Crystal)
• Differential output options (LVCMOS, LVPECL, LVTTL)
• Fixed 2:07 input-to-output frequency ratio

Applications

• Cavium processor systems
• DDR memory interface timing
• PCI bus synchronization

Procurement Notes

Verify the specific suffix AKILF against official Renesas/IDT documentation to confirm package dimensions and tape-and-reel specifications. Ensure the 32-VFQFPN exposed pad footprint matches the target PCB design. Confirm that the fixed 2:07 ratio meets system requirements, as this variant does not offer programmable ratios unlike other models in the series.

Selection Notes

Select this part when a fixed 2:07 division ratio is required for Cavium or PCI applications. It is suitable for designs needing multi-standard input flexibility without external dividers. Compare against the 8430S07I variant if industrial temperature ranges or different packaging options are needed. Ensure the 3.3V nominal supply aligns with the 3.135V–3.465V operating window.

Part Context

This component belongs to the 8430S series of clock generators optimized for high-performance computing and networking applications. Unlike programmable variants in the same family, the 8430S07AKILF features a fixed internal configuration, simplifying board layout by removing the need for SMBus control lines while maintaining low jitter performance for sensitive digital interfaces.

Replacement Considerations

Direct substitutes include other 8430S series devices with identical pinouts and electrical characteristics. Verify that replacement parts support the same 2:07 ratio and input/output signaling standards. Cross-reference with Renesas datasheets for updated package markings and RoHS compliance status.
