8305AGILF-09

Overview

The 8305AGILF-09 is a low skew, 1-to-4 multiplexed differential/LVCMOS-to-LVCMOS/LVTTL fanout buffer manufactured by Renesas Electronics. It features selectable clock inputs that accept either differential or single-ended input levels, including LVPECL, LVDS, LVHSTL, HCSL, SSTL, LVCMOS, and LVTTL. The device provides four LVCMOS/LVTTL outputs with a 7Ω output impedance. Key electrical specifications include a maximum output frequency of 350MHz, a maximum output skew of 35ps, and a maximum part-to-part skew of 700ps. Typical additive phase jitter is 0.04ps RMS.

Feature Summary

• Low skew 1-to-4 fanout buffer with selectable differential or single-ended inputs
• Supports multiple input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL, LVCMOS, LVTTL
• Maximum output frequency of 350MHz with 35ps max output skew
• Internally synchronized clock enable to eliminate runt pulses

Applications

• High-performance clock distribution in computing systems
• Networking and communications equipment requiring precise timing
• Applications demanding well-defined performance and repeatability

Procurement Notes

Verify the specific suffix -09 against official Renesas documentation to confirm any unique ordering or packaging distinctions. Confirm RoHS compliance status and moisture sensitivity level (MSL) requirements for handling and storage prior to procurement.

Selection Notes

Select this component when a low skew solution is required for distributing a single clock source to four loads. Ensure the input signal matches one of the supported differential or single-ended voltage levels. Verify that the 350MHz maximum frequency meets the system timing requirements.

Part Context

This part belongs to the IDT/Renesas family of high-performance clock solutions. It is designed as a fanout buffer to drive multiple loads while maintaining signal integrity. The device is available in a TSSOP package and supports various power supply modes for core and output voltages.

Replacement Considerations

Check for direct pin-compatible replacements within the Renesas portfolio if availability is an issue. Ensure any substitute maintains the same input/output voltage levels and skew specifications.

FAQ

What input signal types are supported?

The 8305AGILF-09 supports selectable differential inputs (LVPECL, LVDS, LVHSTL, HCSL, SSTL) and single-ended inputs (LVCMOS, LVTTL).

What is the maximum output skew?

The maximum output skew is guaranteed at 35ps.

How does the clock enable function work?

The clock enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion or deassertion. Outputs are forced LOW when the clock is disabled.
