8543BGILF

Overview

The Renesas 8543BGILF is a clock fan-out buffer and multiplexer IC housed in a 20-TSSOP package. It features a 2:4 input-to-output ratio with differential LVDS outputs. The device supports multiple input standards including CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL. It operates at a maximum frequency of 650 MHz with a supply voltage range of 3.135V to 3.465V. The component is rated for an industrial operating temperature range of -40°C to +85°C.

Feature Summary

• Supports CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL inputs
• Provides 2:4 fan-out buffering and multiplexing capabilities
• Operates up to 650 MHz with LVDS differential outputs
• Available in a 20-TSSOP surface-mount package

Applications

• Clock distribution networks requiring signal splitting
• Multiplexing multiple clock sources into a single output
• High-speed digital systems utilizing LVDS signaling

Procurement Notes

Verify the specific suffix 'ILFT' against official documentation to confirm tape-and-reel packaging and extended temperature ratings. Confirm current availability status as previous listings indicate potential end-of-life or discontinuation events for related variants in this family.

Selection Notes

Select this component when a 2:4 ratio is required for LVDS clock distribution. Ensure the design accommodates the 3.135V to 3.465V supply requirement. Verify that the input signal levels match one of the supported standards (CML, HCSL, LVDS, etc.) before integration.

Part Context

This part belongs to the ICS8543 series of clock buffers and multiplexers from Renesas. It serves as a specialized timing solution for distributing reference clocks across high-speed data converters and processors. The device integrates multiplexing functionality to allow selection between two input sources.

Replacement Considerations

Check for updated suffixes such as 'ILF' or 'GLF' which may differ in packaging or temperature grade. Consult the manufacturer's PCN documents for any assembly site changes or material substitutions associated with this product line.
