85310AYI-11LFT

Overview

The 85310AYI-11LFT is a low skew, high-performance 1-to-10 differential-to-LVPECL/ECL fanout buffer manufactured by Renesas Electronics. It operates with selectable differential input pairs (CLKX, NCLKX) that accept LVPECL, LVDS, LVHSTL, SSTL, or HCSL interface levels. The device translates single-ended input signals to 3.3V LVPECL levels using resistor bias on the NCLK input. It supports a maximum output frequency of 700MHz and functions within a supply voltage range of 2.375V to 3.8V for LVPECL mode, or -3.8V to -2.375V for ECL mode. The component is characterized for operation between -40°C and 85°C ambient temperature.

Feature Summary

• 1-to-10 differential fanout buffer with selectable input pairs
• Supports multiple input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL
• Maximum output frequency of 700MHz
• Typical output skew of 30ps and part-to-part skew of 140ps

Applications

• Clock distribution systems requiring well-defined performance
• Applications demanding repeatability in clock signal routing
• Systems utilizing LVPECL or ECL output standards

Procurement Notes

Verify RoHS compliance and lead-free status through official manufacturer documentation. Confirm package type and pin configuration against the specific datasheet revision. Ensure supply voltage requirements match the target LVPECL or ECL operating mode before integration.

Selection Notes

Select this component when a 1-to-10 fanout ratio is required with low skew characteristics. Verify compatibility with input signal types such as LVDS or HCSL if translation to LVPECL is needed. Check thermal requirements for the -40°C to 85°C operating range and ensure appropriate power supply rails are available for the selected mode.

Part Context

This part belongs to the 85310I series of clock buffers. It is distinct from other variants like the 853S111 which offers different I/O counts and frequencies. The suffix 'AYI' typically denotes specific package and temperature grade variations within the Renesas portfolio.

Replacement Considerations
