83058AGILFT

Overview

The 83058AGILFT is an obsolete 8:1 single-ended multiplexer from IDT, now part of Renesas Electronics. It features eight selectable single-ended clock inputs and one single-ended output with a nominal impedance of 7Ω at VDDO = 3.3V. The device supports a maximum output frequency of 250MHz and operates with supply voltages including 3.3V/3.3V, 3.3V/2.5V, and 3.3V/1.8V. Key electrical parameters include a maximum propagation delay of 3ns, input skew of 225ps, and part-to-part skew of 475ps at 3.3V supplies. It exhibits typical additive phase jitter of 0.19ps RMS.

Feature Summary

• 8:1 single-ended multiplexer with voltage translation capability via adjustable VDDO (3.3V, 2.5V, or 1.8V)
• Maximum operating frequency of 250MHz with low skew characteristics
• Output enable pin for high-impedance state control during testing or debug
• Available in lead-free RoHS 6 compliant 16-pin TSSOP package

Applications

• Voltage translation between different clock domains
• Clock distribution systems requiring low skew performance
• Board-level testing and debug scenarios utilizing output enable functionality

Procurement Notes

The 83058AGILFT is listed as obsolete. Verification of current availability requires checking distributor stock status directly. As an end-of-life component, alternative sourcing may be limited to existing inventory or qualified replacement parts. Ensure compatibility with the functional replacement 854S058I if transitioning designs.

Selection Notes

Select this component for applications requiring an 8:1 single-ended multiplexer with specific voltage translation needs between 3.3V, 2.5V, and 1.8V domains. Verify that the 250MHz maximum frequency and 3ns propagation delay meet system timing requirements. Consider the 16 TSSOP package constraints and -40°C to 85°C operating temperature range for environmental suitability.

Part Context

The 83058I belongs to the IDT family of High Performance Clock Solutions. Following IDT's acquisition by Renesas Electronics Corporation, this product line is managed under Renesas. The device is designed for low skew clock distribution and serves as a precursor to newer multiplexer solutions within the portfolio.

Replacement Considerations

The 854S058I is documented as a functional replacement for the 83058I series. Designers should verify pinout compatibility and electrical parameter alignment when substituting the obsolete 83058AGILFT with the 854S058I.
