8305AGLF-TEJ

Overview

The 8305AGLF-TEJ 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, LVCMOS, and LVTTL. The device provides four LVCMOS/LVTTL outputs with an 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 (RoHS 6) TSSOP-16 package.

Feature Summary

• Selectable differential or single-ended clock inputs supporting multiple voltage standards
• Low skew performance with guaranteed output and part-to-part repeatability
• Internally synchronized clock enable to eliminate runt pulses during asynchronous assertion/deassertion
• Separate output enable pin for controlling active or high impedance states

Applications

• High-performance clock distribution networks requiring precise timing
• Systems demanding well-defined performance and repeatability
• Multiplexing differential or single-ended clock signals to LVCMOS/LVTTL loads

Procurement Notes

Verify the specific suffix TEJ against official documentation, as standard listings typically reference AGLF or AGLFT variants. Confirm current availability status, as related models may be obsolete. Ensure compliance with RoHS 6 requirements and check for any product discontinuance notifications prior to procurement.

Selection Notes

Select this component when a low skew fanout buffer is required for 1-to-4 signal distribution. It is suitable for applications needing flexible input compatibility with various differential and single-ended standards. Consider the 350MHz maximum frequency and specific power supply configurations when designing the circuit.

Part Context

This component belongs to the IDT family of High Performance Clock Solutions, now under Renesas Electronics. It is categorized under Clock & Timer ICs, specifically as a Fanout Buffer. The device is designed to provide reliable clock distribution with minimal skew, making it a key element in timing-critical digital systems.

Replacement Considerations

Check for direct substitutes within the 8305 series, such as the 8305AGLF or 8305AGLFT. Verify pinout and electrical specifications match before substitution. Note that some variants may have different packaging or status.
