8305AGILFT-09

Overview

The 8305AGILFT-09 is a low skew, 1-to-4 multiplexed differential/LVCMOS-to-LVCMOS/LVTTL fanout buffer manufactured by Renesas Electronics Corporation. 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 nominal output impedance of 7Ω. It supports a maximum output frequency of 350MHz, with a maximum output skew of 35ps and part-to-part skew of 700ps. Typical additive phase jitter (RMS) is 0.04ps. Power supply modes include Core/Output configurations of 3.3V/3.3V, 3.3V/2.5V, 3.3V/1.8V, and 3.3V/1.5V. It operates within an ambient temperature range of 0°C to 70°C and is available in a lead-free TSSOP package.

Procurement Notes

Verify component authenticity through authorized distributors. Confirm RoHS compliance and moisture sensitivity level prior to procurement. Check for obsolescence status as the base model may be discontinued. Ensure packaging type matches production requirements.

Selection Notes

Select based on required input signal compatibility (differential vs single-ended) and output voltage levels. Consider thermal management for 0°C to 70°C operating range. Verify power supply configuration matches system design constraints. Evaluate skew specifications against timing requirements.

Part Context

The 8305AGILFT-09 belongs to the IDT/Renesas high-performance clock solutions family. It is designed for applications requiring reliable clock distribution with minimal skew. The device integrates clock enable synchronization to eliminate runt pulses during asynchronous assertion/deassertion.

Replacement Considerations

Functional replacements may include other low skew fanout buffers from Renesas or IDT product lines. Verify pin compatibility and electrical parameters before substitution. Consult official documentation for recommended alternatives if the part is obsolete.
