8531AY-01LF

Overview

The 8531AY-01LF is a clock driver and distribution component manufactured by Renesas Electronics Corporation. It functions as a buffer with five differential LVPECL outputs. The device operates on a single 3.3V supply voltage, with an operating range of 3.135V to 3.465V. It supports output frequencies up to 267MHz. The component is housed in a 32-pin TQFP package and is designed for surface mount installation. It is classified under Clock Drivers & Distribution within the Clock & Timer ICs subcategory.

Feature Summary

• Five differential 3.3V LVPECL output pairs
• Selectable differential clock inputs (LVPECL, LVDS, LVHSTL, HCSL, SSTL)
• Output frequency range: 15.625MHz to 350MHz
• Cycle-to-cycle jitter: 60ps maximum

Applications

• High-speed data communication systems
• Server and storage clock distribution
• Telecommunications equipment timing

Part Context

This part belongs to the 8531A series of clock buffers. It is distinct from other variants like the 8531BMI-01LF which uses an SOIC-20 package. The 8531AY-01LF specifically utilizes a TQFP-32 package. It is often grouped with similar fanout buffers such as the 8535I-31 or 8538-31 depending on the required input/output configuration.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Users should verify pin compatibility and electrical specifications when considering alternative components from the same family or different manufacturers.
