8545AG-01LF

Overview

The 8545AG-01LF is a low skew, high-performance clock fanout buffer manufactured by Renesas Electronics Corporation. It functions as a 1-to-4 distribution IC with a maximum operating frequency of 650 MHz. The device accepts LVCMOS or LVTTL inputs and provides four differential LVDS output pairs. It operates within a supply voltage range of 3.135V to 3.465V and supports an industrial temperature range of 0°C to 70°C. The component is housed in a 20-TSSOP package with a width of 4.40mm.

Feature Summary

• Converts single-ended LVCMOS/LVTTL clock signals into four differential LVDS outputs for noise immunity.
• Provides low skew performance suitable for high-speed digital systems requiring precise timing.
• Supports redundant or selectable frequency fanout applications through dedicated input configurations.

Applications

• High-performance computing systems requiring precise clock distribution.
• Telecommunications infrastructure equipment.
• Data acquisition systems needing low jitter signal integrity.
• Industrial control systems utilizing LVDS interfaces.

Procurement Notes

Verify the specific suffix 'AG' against official Renesas documentation to confirm the exact temperature grade and package variant. Ensure the application circuit matches the required 3.135V to 3.465V supply voltage range. Confirm that the 20-TSSOP footprint aligns with the PCB design specifications before finalizing procurement orders.

Selection Notes

Select this component when a single-ended clock source must be distributed to multiple LVDS receivers with minimal skew. It is appropriate for designs requiring 1:4 fanout ratios at frequencies up to 650 MHz. Consider alternative models if dual-input redundancy or different packaging options are required for the specific system architecture.

Part Context

This part belongs to the 8545 series of clock buffers from Renesas. The series includes variants such as the 8545BG and 8545AG, which differ in input/output configurations and temperature ranges. The 8545AG-01LF specifically denotes the 1:4 LVCMOS-to-LVDS configuration within the commercial temperature grade subset of the family.

Replacement Considerations

The 8545AG-02LF is a related variant offering 2:4 functionality. Verify pin compatibility and electrical parameters before substitution. No other direct public substitutes are confirmed in the provided data.
