859S0424BGILF

Overview

The 859S0424BGILF is a clock driver and distribution component manufactured by Renesas Electronics. It functions as a 4:2 differential LVPECL to LVDS clock multiplier, designed for high-speed signal conversion and distribution in electronic systems. The device is housed in a TSSOP-20 package and belongs to the 859S0412 series. This specific part number indicates the presence of an RoHS-compliant lead-free finish (suffix 'R') and tube packaging (suffix 'T'). The component operates within standard commercial temperature ranges typical for this class of clock multiplexers.

Feature Summary

• Converts four differential LVPECL inputs to two LVDS outputs
• Functions as a clock multiplier with 4:2 ratio
• Available in a compact TSSOP-20 surface-mount package

Applications

• High-speed data communication systems requiring clock domain conversion
• Server and storage infrastructure clock distribution networks
• Telecommunications equipment utilizing mixed voltage logic levels

Procurement Notes

Verify the exact suffix configuration against the manufacturer's current datasheet, as alphanumeric codes define packaging and environmental compliance. Confirm availability status, as clock drivers in this series may be subject to end-of-life notices or production changes. Ensure the selected variant matches the required input/output voltage levels and pinout compatibility for the target design.

Selection Notes

Select this component when a design requires translating LVPECL signals to LVDS with a 4-to-2 reduction ratio. Verify that the system power supplies support the specific VDD and VDDO requirements for LVPECL and LVDS interfaces respectively. Check thermal performance constraints associated with the TSSOP-20 package for the intended operating environment.

Part Context

This part belongs to the Renesas 859S family of high-performance clock solutions. The 859S0412 series generally encompasses devices handling differential clock distribution and format conversion. The 859S0424 variant specifically addresses the need for reducing channel count while changing signaling standards from LVPECL to LVDS.

Replacement Considerations

Consult the official Renesas replacement guide for obsolete components. Potential functional equivalents may include other IDT or Renesas clock multipliers with matching 4:2 LVPECL-to-LVDS specifications. Verify pin-to-pin compatibility before substitution.
