8305AGILF

Overview

The 8305AGILF 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, LVCMOS, and LVTTL. The device provides four LVCMOS/LVTTL outputs with a maximum output frequency of 350MHz. Key electrical parameters include a maximum output skew of 35ps and a maximum part-to-part skew of 700ps. Typical additive phase jitter is 0.04ps RMS. It operates within an ambient temperature range of 0°C to 70°C.

Feature Summary

• Low skew performance with 35ps maximum output skew and 700ps maximum part-to-part skew
• Selectable differential or single-ended (LVCMOS/LVTTL) clock inputs supporting multiple voltage standards
• Four LVCMOS/LVTTL outputs with 7Ω output impedance
• Internally synchronized clock enable to eliminate runt pulses during asynchronous assertion/deassertion

Applications

• High-performance clock distribution networks requiring precise timing alignment
• Systems demanding well-defined performance and repeatability in clock routing
• Multiplexing differential or single-ended clock sources to multiple downstream components

Part Context

The 8305AGILF belongs to the IDT/Renesas family of high-performance clock solutions. It is designed as a fanout buffer and multiplexer, bridging the gap between various input clock standards and standard logic outputs. This component is distinct from simple buffers due to its multiplexing capability and low-skew characteristics optimized for complex digital systems.

Replacement Considerations

The 8305AGILF is listed as obsolete. Potential replacements within the same functional category include other low-skew fanout buffers or multiplexers from Renesas or IDT, such as the 83058 series for higher channel counts or different input/output configurations. Verification of pin compatibility and electrical specifications against the original datasheet is required before substitution.
