854S057BGILF

Overview

The Renesas 854S057BGILF is a 4:1 or 2:1 LVDS clock multiplexer with an internal oscillator, manufactured by Renesas Electronics. It operates within a supply voltage range up to 2.5 V and features a propagation delay of 800 ps. The device supports four input lines and provides one output line, housed in a TSSOP-20 package suitable for SMD/SMT installation. It functions reliably across an ambient temperature range from -40°C to +85°C. This component belongs to the 854S057BI series and is classified under encoders, decoders, multiplexers, and demultiplexers.

Feature Summary

• Configurable 4:1 or 2:1 LVDS clock multiplexer functionality
• Integrated internal oscillator for clock generation
• Low propagation delay of 800 ps maximum
• Operates on a single 2.5 V power supply

Applications

• Clock distribution networks requiring low skew
• High-speed data communication systems
• Networking equipment timing circuits
• Computing infrastructure clock management

Procurement Notes

The 854S057BGILF is listed as an End-of-Life (EOL) product by Renesas Electronics. Availability is restricted, and Mouser indicates that the product is not currently sold in certain regions. Verification of current stock status and alternative sourcing channels is required before procurement planning due to its discontinued status.

Selection Notes

Designers should consider the EOL status when selecting this component for new designs. The TSSOP-20 package limits pin count compared to larger footprints. Verify that the 800 ps propagation delay meets system timing requirements. Ensure the 2.5 V supply voltage aligns with the target board's power rails. Check RoHS compliance details if environmental regulations are critical.

Part Context

This part belongs to the Renesas 854S057BI series of clock multiplexers. It shares characteristics with other variants like the 854S057AGILFT, though packaging differs (Tube vs. Reel/Cut Tape). The device serves as a timing solution for differential signal routing, distinct from buffer drivers like the 8545B series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the EOL status, engineers must evaluate functional equivalents from the same family or consult manufacturer resources for recommended upgrades.
