854105AGLF

Overview

The 854105AGLF is a low skew, high-performance 1-to-4 LVCMOS/LVTTL-to-LVDS clock fanout buffer manufactured by Renesas Electronics Corporation. It operates within an ambient temperature range of 0°C to 70°C and utilizes a 16-TSSOP package with a width of 4.40mm. The device supports an output frequency range up to 250MHz with an output skew of 55ps. It features one output bank delivering LVDS signals at 3.3V. The component is lead-free and RoHS compliant, currently classified as obsolete.

Feature Summary

• Converts single-ended LVCMOS or LVTTL inputs to differential LVDS outputs for reliable signal distribution.
• Provides low skew performance to maintain precise timing alignment across multiple clock paths.
• Supports high-frequency operation up to 250MHz for demanding digital system requirements.

Applications

• High-speed data acquisition systems requiring precise clock distribution.
• Telecommunications equipment utilizing LVDS signaling standards.
• Test and measurement instruments needing low jitter clock buffers.

Procurement Notes

Verify the obsolete status before integration into new designs. Confirm availability through secondary market channels if existing inventory is required. Ensure the 16-TSSOP footprint matches the target PCB layout. Validate that the 3.3V LVDS output voltage aligns with downstream receiver specifications. Check for RoHS compliance documentation for regulatory adherence.

Selection Notes

Choose this component when converting single-ended logic levels to differential LVDS is necessary. Consider the 250MHz maximum frequency limit for application suitability. Evaluate the 55ps skew specification against timing budget requirements. Assess the 1-to-4 fanout capability against load distribution needs. Verify thermal performance within the specified operating temperature range.

Part Context

This part belongs to Renesas' family of clock buffer and driver integrated circuits designed for signal integrity optimization. It serves as a distribution element in complex digital architectures where noise immunity and timing precision are critical. The device bridges standard logic interfaces with high-speed differential transmission lines.

Replacement Considerations

No public confirmed substitute part numbers are available for this obsolete component. Designers should evaluate newer Renesas LVDS buffer families or cross-reference compatible devices from other manufacturers based on pinout and electrical specifications.
