8543BGILFT

Overview

The ICS8543BGILFT is a clock fan-out buffer and multiplexer manufactured by Renesas Electronics Corporation. It features a 2:4 input-to-output ratio with differential CML, HCSL, LVDS, LVHSTL, LVPECL, or SSTL inputs and LVDS outputs. The device operates at a maximum frequency of 650 MHz with a supply voltage range of 3.135V to 3.465V. Packaged in a 20-TSSOP (0.173", 4.40mm wide) surface-mount enclosure, it supports an industrial operating temperature range of -40°C to 85°C.

Feature Summary

• Supports multiple input standards including CML, HCSL, LVDS, LVHSTL, LVPECL, and SSTL
• Provides four LVDS differential outputs for clock distribution
• Operates within a 3.135V to 3.465V supply voltage range
• Available in a 20-TSSOP package suitable for surface mount applications

Applications

• High-speed data communication systems requiring clock distribution
• Telecommunications infrastructure equipment
• Server and storage system clock networks

Procurement Notes

Verify the specific suffix 'ILFT' against official Renesas documentation to confirm tape-and-reel packaging and lead-free status. Confirm current component availability as previous variants may have different lifecycle statuses. Ensure compatibility with existing board design parameters before procurement.

Selection Notes

Select this component when a 2:4 fan-out buffer with LVDS outputs is required for frequencies up to 650 MHz. Verify that the system power supply falls within the 3.135V to 3.465V range. Ensure the application environment stays within the -40°C to 85°C operating temperature specification.

Part Context

This part belongs to the ICS8543 family of clock buffers. The base model ICS8543 supports similar functionality but may differ in packaging or temperature range. The BGILFT designation specifies the 20-TSSOP package, industrial temperature grade, and reel packaging format distinct from tube-packaged variants like the BGILF.

Replacement Considerations

Direct substitutes include other ICS8543 variants with matching electrical specifications. Verify pinout compatibility and output drive strength when replacing with similar clock buffer devices from Renesas or other manufacturers.
