8533AGI-31LF

Overview

The Renesas ICS8533AGI-31LF is a low skew, high-performance 1-to-4 Crystal Oscillator/Differential-to-3.3V LVPECL fanout buffer from the HiPerClockS family. It features selectable differential CLK/nCLK or crystal oscillator inputs and provides four differential LVPECL output pairs. The device operates on a full 3.3V supply with an ambient temperature range of -40°C to 85°C. Key electrical parameters include a maximum output frequency of 650MHz, typical output skew of 25ps, part-to-part skew of 150ps, and propagation delay of 1.5ns.

Feature Summary

• Four differential 3.3V LVPECL output pairs
• Selectable differential CLK/nCLK or crystal oscillator interface
• Maximum output frequency: 650MHz
• Output skew: 25ps (typical); Part-to-part skew: 150ps (typical)
• Propagation delay: 1.5ns (typical)

Applications

• High performance clock distribution systems
• Applications requiring well-defined performance and repeatability
• Crystal oscillator to LVPECL translation

Procurement Notes

Verify RoHS compliance status by checking for the 'LF' suffix in the ordering information. Confirm package type availability, as the component is offered in both tube and tape & reel configurations. Ensure the specific variant matches the required lead-free specifications for the target assembly process.

Selection Notes

Select this component when a 1-to-4 fanout buffer with low skew characteristics is required for 3.3V LVPECL applications. Consider the 650MHz maximum frequency limit and the specific input options (differential vs. crystal) during design. Verify that the thermal resistance and power dissipation requirements align with the system's cooling capabilities.

Part Context

The ICS8533AGI-31LF belongs to the HiPerClockS family of high-performance clock solutions originally developed by Integrated Device Technology (IDT), which was acquired by Renesas Electronics Corporation. This lineage ensures compatibility with established clocking architectures and design practices associated with the HiPerClockS brand.
