853S202AYILFT

Overview

The 853S202AYILFT is a high-performance 12:2 differential-to-LVPECL clock multiplexer designed for demanding signal integrity applications. It operates with a maximum output frequency of 3GHz and supports fully differential architecture. The device accepts twelve selectable differential clock or data inputs, including LVPECL and LVDS levels, routing any input to either of the two LVDS outputs. It features low propagation delay and an additive phase jitter of 0.114ps typical at 155.52MHz under 3.3V operation. The component supports full 3.3V or 2.5V operating supply modes and functions within an ambient temperature range of -40°C to 85°C.

Feature Summary

• Supports twelve selectable differential clock or data inputs capable of accepting LVPECL or LVDS signal levels.
• Routes selected inputs independently to two LVDS outputs with fully differential architecture.
• Delivers low propagation delay and minimal additive phase jitter for precise timing applications.
• Operates in both full 3.3V and 2.5V supply modes for flexible system integration.

Applications

• Clock distribution circuits requiring high-speed signal routing
• High-frequency data acquisition systems
• Telecommunications infrastructure equipment

Procurement Notes

Verify the specific suffix 'YILFT' against official Renesas documentation to confirm package type, tape-and-reel quantity, and lead-free status. Ensure the ordering code matches the exact electrical specifications and temperature range required for your design. Cross-reference the part number with current availability and lifecycle status before finalizing procurement plans.

Selection Notes

Select this component when a design requires multiplexing multiple differential sources into LVPECL/LVDS formats with minimal skew. Consider its 3GHz capability and low jitter profile for high-speed serial links. Evaluate power supply requirements for 2.5V or 3.3V operation and ensure thermal management aligns with the specified industrial temperature range.

Part Context

This part belongs to Renesas' family of high-performance clock buffers and drivers. It complements other fanout buffers and translators by providing complex multiplexing functionality rather than simple signal splitting or translation. It addresses needs for dynamic clock source selection in high-speed digital systems.

Replacement Considerations

Consult official Renesas substitution guides for verified alternatives. Generic cross-references may not match the specific 12:2 topology, 3GHz speed, or differential input/output configurations. Verify pin compatibility and electrical parameters before considering any substitute parts.
