853S057AGILFT

Overview

The Renesas 853S057AGILFT is a high-speed 4:1 differential-to-3.3V or 2.5V LVPECL/ECL clock data multiplexer from the Hiperclocks family. It operates at maximum input/output frequencies up to 3GHz with a typical additive phase jitter of 0.073ps RMS at 622.08MHz. The device features four differential CLKx/NCLKx input pairs capable of accepting LVPECL, LVDS, CML, or SSTL levels. It offers a maximum propagation delay of 615ps and part-to-part skew of 250ps. Operating temperatures range from -40°C to 85°C, and it is available in lead-free packages compliant with RoHS standards.

Feature Summary

• High-speed 4:1 differential multiplexer supporting up to 3GHz operation
• Accepts multiple input interface levels including LVPECL, LVDS, CML, and SSTL
• Low additive phase jitter (0.073ps typ @ 622.08MHz) and low propagation delay (615ps max)
• Dual voltage supply options for LVPECL (2.375V–3.465V VCC) and ECL (-3.465V to -2.375V VEE)

Applications

• Clock distribution circuits requiring high-speed signal selection
• Networking and communications equipment
• Computing systems utilizing differential clock signals

Procurement Notes

Verify the specific package type and lead-free status against the manufacturer's current datasheet before ordering. Confirm that the selected operating voltage aligns with either the LVPECL or ECL mode requirements. Ensure compatibility with the system's control logic levels for the multiplexer select inputs.

Selection Notes

Select this component when a 4:1 multiplexing function is required for differential clock signals up to 3GHz. Consider the input signal format (LVPECL, LVDS, CML, SSTL) to ensure compatibility with the source clocks. Evaluate the power supply constraints to determine if the LVPECL or ECL operating mode is more suitable for the design.

Part Context

The 853S057AGILFT belongs to the Renesas Hiperclocks family of high-performance clock solutions. This series focuses on providing low-jitter, high-speed timing components for demanding applications. The 'GILFT' suffix typically indicates a lead-free TSSOP package variant within the product line.

Replacement Considerations

Consult official Renesas documentation for direct pin-compatible replacements. Verify electrical parameters such as jitter and frequency limits when considering alternative multiplexers.
