853S111AYILF

Overview

The Renesas Electronics Corporation 853S111AYILF is a low skew, high-performance 1-to-10 differential-to-LVPECL/ECL fanout buffer. It operates from a single 2.5V or 3.3V power supply with an operating voltage range of 2.375V to 3.465V. The device features a typical additive phase jitter of 0.07ps RMS and supports frequencies up to 2.5GHz. It is housed in a 32-TQFP package with dimensions of 7.0 x 7.0mm and operates within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Provides one-to-ten differential-to-LVPECL/ECL fanout buffering capability
• Characterized for operation from either 2.5V or 3.3V power supplies
• Delivers low skew performance suitable for demanding clock distribution applications

Applications

• Clock distribution networks requiring well-defined performance
• High-speed digital systems utilizing LVPECL or ECL signaling
• Applications demanding repeatability and part-to-part skew characteristics

Procurement Notes

Verify the specific suffix 'AYILF' against current Renesas documentation to confirm package type and lead-free status. Ensure compatibility with 2.5V or 3.3V supply rails as specified. Confirm availability through authorized channels as stock levels fluctuate. Check for any recent product change notices affecting pinout or electrical parameters before finalizing procurement.

Selection Notes
