8545BGILFT

Overview

The Renesas 8545BGILFT is a clock buffer integrated circuit designed for high-speed signal distribution. It features a 2:4 input-to-output ratio and supports maximum frequencies up to 650 MHz. The device operates on a single supply voltage and is housed in a 20-lead TSSOP package with an exposed pad. This component is engineered to provide low skew and precise timing characteristics for demanding digital applications requiring reliable clock fan-out.

Feature Summary

• Clock Buffer type with 2:4 Input:Output ratio
• Maximum operating frequency of 650 MHz
• Available in 20-TSSOP (Exposed Pad) package

Applications

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

Procurement Notes

Verify the specific suffix 'ILFT' against the manufacturer's current datasheet to confirm lead-free status, tape-and-reel packaging quantity, and industrial temperature range specifications. Ensure compatibility with existing board layouts for the 20-TSSOP footprint before procurement.

Selection Notes

Select this component when a 2-input to 4-output clock fan-out solution is required at frequencies approaching 650 MHz. Compare propagation delay and output skew parameters against system timing budgets. Confirm that the 20-TSSOP package size fits within the available PCB area constraints.

Part Context

This part belongs to the 8545B series of clock buffers from Renesas Electronics. Variants within this series may differ by package type, temperature rating, or output configuration. The 'I' typically denotes industrial temperature range, while 'LF' indicates lead-free composition, and 'T' specifies reel packaging.

Replacement Considerations

Direct replacements must match the 2:4 ratio, 650 MHz frequency limit, and 20-TSSOP package. Verify pinout compatibility and electrical parameters such as supply voltage and output drive strength before substituting with other manufacturers' clock buffer ICs.
