85310AYI-11LF

Overview

The ICS85310AYI-11LF is a low skew, high-performance 1-to-10 differential-to-2.5V/3.3V ECL/LVPECL fanout buffer manufactured by Renesas Electronics Corporation. It translates standard differential input signals to LVPECL levels with resistor bias on the NCLK input. The device supports an operating supply voltage range of VCC = 2.375V to 3.8V for LVPECL mode and VEE = -3.8V to -2.375V for ECL mode. Key electrical parameters include a maximum output frequency of 700MHz, typical output skew of 30ps, part-to-part skew of 140ps, propagation delay of 2ns, and additive phase jitter RMS of less than 0.13ps.

Feature Summary

• Provides ten differential outputs compatible with 2.5V or 3.3V LVPECL/ECL standards
• Accepts multiple differential input interface levels including LVPECL, LVDS, LVHSTL, SSTL, and HCSL
• Guarantees low output skew (30ps typ) and part-to-part skew (140ps typ) for precise clock distribution
• Operates within an ambient temperature range of -40°C to 85°C

Applications

• Clock distribution networks requiring well-defined performance and repeatability
• Systems demanding translation of various differential signal levels to LVPECL
• High-speed digital interfaces utilizing ECL or LVPECL logic families

Procurement Notes

Verify the specific suffix 'AYI-11LF' against official Renesas documentation to confirm package type, lead-free status, and RoHS compliance. Confirm current production status as older variants may be obsolete or subject to last-time-buy notices. Ensure supply chain sources provide valid traceability for industrial temperature grade components.

Selection Notes

Select this component when a single differential clock source must drive up to ten loads with minimal skew. Verify that the system power supply can accommodate the required 2.5V or 3.3V rails. Ensure input signal levels match the supported interfaces (LVPECL, LVDS, etc.) and that the 700MHz maximum frequency meets system requirements.

Part Context

This part belongs to the ICS85310 family of fanout buffers designed for high-speed clock distribution. It serves as a bridge between diverse input clock sources and downstream LVPECL/ECL receivers. The '85310' designation indicates a 1-to-10 configuration, distinguishing it from other fanout ratios in the product line.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided data. Check Renesas documentation for direct pin-compatible replacements or updated series members if this specific variant is discontinued.
