853S111BKILF

Overview

The 853S111BKILF is a low skew, high-performance differential-to-LVPECL/ECL fanout buffer manufactured by Renesas Electronics. It features a 1-to-10 input-to-output ratio and supports maximum frequencies up to 2.5 GHz. The device operates within a supply voltage range of 2.375V to 3.8V for LVPECL mode and -2.375V to -3.8V for ECL mode. It is housed in a 32-pin VFQFN package (5.0 x 5.0 mm) and functions across an ambient temperature range of -40°C to 85°C.

Feature Summary

• 1:10 Differential-to-LVPECL/ECL Fanout Buffer configuration
• Maximum operating frequency of 2.5 GHz
• Low additive phase jitter with typical RMS value of 0.03ps
• Guaranteed output skew characteristics for repeatability

Applications

• High-speed clock distribution networks
• Data communication systems requiring precise timing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix BKILF against official Renesas documentation to confirm the exact package type and lead-free status. Ensure compatibility with the required 32-pin VFQFN footprint during procurement planning.

Selection Notes

Select this component when a single differential clock source must drive ten parallel LVPECL or ECL loads. Verify that the system power supply aligns with the specified 2.375V to 3.8V range and that the thermal environment remains within the -40°C to 85°C operational limits.

Part Context

This part belongs to the 853S111BI series of clock buffers. It shares functional similarities with other variants like the 853S111BYILFT but differs in packaging. The BKILF designation specifically identifies the VFQFN package option within this product family.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided data. Cross-reference with the 853S111BI series for pin-compatible alternatives if necessary.
