870S208BKLFT

Overview

The Renesas 870S208BKLFT is a clock buffer and driver integrated circuit manufactured by Renesas Electronics Corporation. It features a 1-to-4 distribution ratio with differential input and output capabilities. The device operates at a maximum frequency of 250MHz and supports an HCSL input signal format, converting it to LP-HCSL outputs. It functions within a supply voltage range of 3V to 3.6V and is designed for commercial temperature applications between 0°C and 70°C. The component is housed in a 32-pin VFQFN package with an exposed pad.

Feature Summary

• 1:4 Clock Distribution Ratio
• Maximum Frequency of 250MHz
• HCSL Input to LP-HCSL Output Conversion
• Differential Input and Output Signals

Applications

• General-purpose clock distribution in digital systems
• Buffering high-speed clock signals
• Fan-out buffering for peripheral devices

Procurement Notes

Verify the specific suffix 'BKLFT' against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 32-VFQFN package dimensions match the target PCB footprint. Confirm RoHS compliance status through current regulatory documentation before integration into final assemblies.

Selection Notes

Select this component when a single differential clock source requires fan-out to four distinct loads. Verify that the system power supply remains stable within the 3V to 3.6V operating range. Ensure the design accommodates the thermal requirements of the exposed pad on the 32-VFQFN package for reliable operation at 250MHz.

Part Context

This part belongs to the 870S series of clock buffers and drivers from Renesas. It serves as a signal conditioning component for distributing reference clocks across multiple subsystems. The device provides signal integrity maintenance while expanding the clock drive capability for downstream logic components.

Replacement Considerations

Consult the manufacturer's obsolescence notices and substitution guide for verified alternative part numbers. Cross-reference pin configurations and electrical parameters with any potential replacement components to ensure functional equivalence.
