85310AYI-01LF

Overview

The Renesas Electronics Corporation 85310AYI-01LF is a low skew, high performance dual 1-to-5 differential-to-2.5V/3.3V ECL/LVPECL fanout buffer. It accepts standard differential input levels on CLKx and nCLKx pairs and operates from either a 2.5V or 3.3V power supply. The device guarantees output skew of 270ps (typical) and part-to-part skew of 270ps (typical), with a propagation delay of 1.7ns (typical). Additive phase jitter RMS is less than 0.13ps (typical). It supports LVPECL mode with VCC = 2.375V to 3.8V and VEE = 0V, or ECL mode with VCC = 0V and VEE = -3.8V to -2.375V.

• Additive phase jitter RMS < 0.13ps typical
• Compatible with 2.5V and 3.3V power supplies

Applications

• Clock distribution systems requiring defined performance and repeatability
• High-speed digital signal processing equipment
• Telecommunications infrastructure

Procurement Notes

Verify the specific suffix '01LF' against official Renesas documentation to confirm pinout and electrical parameters, as variations exist within the 85310 family. Confirm RoHS compliance status and lead-free packaging details directly from the manufacturer's datasheet before procurement.

Selection Notes

Select this component for applications requiring dual 1-to-5 clock buffering with low skew. Ensure the system design accommodates the required 2.5V or 3.3V supply rails. Verify that the input signal levels are compatible with the CLKx/nCLKx differential inputs.

Part Context

The 85310AYI-01LF belongs to the ICS85310 series of fanout buffers designed for high-performance clock distribution. This series is characterized by its ability to translate various differential input signals into LVPECL/ECL outputs while maintaining tight skew specifications across multiple channels.

Replacement Considerations

Consult the official Renesas cross-reference guide for verified substitutes. Generic equivalents may not match the specific 270ps skew or jitter performance metrics.
