83056AGI-01LF

Overview

The 83056AGI-01LF is a low skew, 4:1 multiplexed differential/LVCMOS-to-LVCMOS 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 outputs with an output impedance of 7 ohms. It supports maximum output frequencies up to 350MHz with a maximum output skew of 35ps and part-to-part skew of 700ps. Additive phase jitter is typically 0.04ps RMS. Power supply modes include Core/Output configurations such as 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.

Feature Summary

• Supports selectable differential or single-ended clock inputs for versatile signal compatibility
• Provides four LVCMOS outputs with guaranteed low skew characteristics for high repeatability
• Internally synchronized clock enable eliminates runt pulses during asynchronous assertion

Applications

• High-performance clock distribution systems requiring low skew
• Applications demanding well-defined performance and repeatability
• Systems utilizing mixed differential and single-ended clock sources

Procurement Notes

Verify the specific suffix and voltage configuration against current datasheets, as product status may vary. Confirm package dimensions and moisture sensitivity levels prior to integration. Ensure thermal management aligns with the specified operating temperature range. Cross-reference pinouts with official documentation to prevent design errors during PCB layout.

Selection Notes

Select this component when low skew and high-frequency operation are critical for system timing integrity. Consider the available power supply modes to match core and output voltage requirements. Evaluate the input signal types to ensure compatibility with existing clock sources. Verify package availability and lead counts for manufacturing constraints.

Part Context

This component belongs to Renesas' family of High Performance Clock Solutions, specifically designed for precise timing applications. It serves as a fanout buffer and multiplexer, bridging various clock standards to LVCMOS outputs. The device is engineered for reliability in environments requiring strict timing control and signal integrity across multiple channels.

Replacement Considerations

Check for direct footprint-compatible alternatives within the same product family. Verify electrical parameter equivalence, particularly skew and jitter specifications. Ensure pin-to-pin compatibility if board re-spin is not feasible. Consult official substitution guides for recommended upgrades or legacy replacements.
