8305AGLFT-TEJ

Overview

The Renesas 8305AGLFT-TEJ is a low skew, 1-to-4 multiplexed differential/LVCMOS-to-LVCMOS/LVTTL fanout buffer. It features selectable clock inputs accepting either differential or single-ended input levels. The CLK and nCLK pair supports LVPECL, LVDS, LVHSTL, HCSL, and SSTL levels, while the LVCMOS_CLK input accepts LVCMOS and LVTTL signals. The device provides four LVCMOS or LVTTL outputs with an output impedance of 7Ω. It operates at a maximum frequency of 350 MHz with a typical additive phase jitter of 0.04ps RMS. The part is available in a lead-free package.

Feature Summary

• Supports selectable differential or single-ended clock inputs for flexible signal integration
• Provides four LVCMOS or LVTTL outputs with guaranteed low skew characteristics
• Internally synchronized clock enable eliminates runt pulses during asynchronous assertion

Applications

• Clock distribution systems requiring reliable signal management
• Systems demanding well-defined performance and repeatability
• High-performance clock solutions for digital circuits

Procurement Notes

Verify component status as this specific part number may be obsolete or discontinued. Confirm availability through authorized distributors or alternative suppliers. Check for valid replacement part numbers if direct procurement is not possible. Ensure compliance with RoHS standards and moisture sensitivity levels before ordering.

Selection Notes

Select this component for applications requiring a 1-to-4 fanout buffer with low skew. Consider its support for multiple input voltage levels including differential and single-ended types. Evaluate the 350 MHz maximum frequency against system requirements. Ensure the 16-TSSOP package fits the design constraints.

Part Context

The 8305AGLFT-TEJ belongs to the IDT/Renesas family of high-performance clock solutions. It is designed as a fanout buffer to distribute clock signals from two inputs to four outputs. This series emphasizes low skew and precise timing characteristics suitable for demanding digital applications.

Replacement Considerations

Check for official substitute part numbers from Renesas or IDT if this model is unavailable. Verify compatibility regarding pin configuration, electrical specifications, and package type. Consult manufacturer documentation for recommended replacements.
