870S208BKLF

Overview

The Renesas 870S208BKLF is a clock buffer and driver integrated circuit designed for high-speed signal distribution. It features a 1-to-4 fan-out configuration, accepting a single input to drive four differential outputs. The device supports maximum operating frequencies up to 250 MHz, making it suitable for demanding digital applications requiring precise timing alignment. It operates within a supply voltage range of 3.135V to 3.465V and is housed in a 32-pin VFQFN package with an exposed pad for thermal management.

Feature Summary

• 1:4 Fan-Out Clock Buffer Configuration
• Maximum Operating Frequency of 250 MHz
• Differential Output Capability
• 32-Pin VFQFN Package with Exposed Pad

Applications

• High-speed data communication systems
• Server and storage infrastructure clock distribution
• Networking equipment timing circuits

Procurement Notes

Verify the specific suffix 'BKLF' against the official Renesas datasheet to confirm pinout compatibility and electrical specifications. Ensure that the 32-VFQFN footprint matches the target PCB design. Confirm RoHS compliance status through current manufacturer documentation before integration.

Selection Notes

Select this component when a single reference clock requires distribution to four separate loads with minimal skew. Verify that the input signal amplitude and format are compatible with the buffer's input stage. Ensure the system power supply remains stable within the 3.135V to 3.465V range to maintain signal integrity.

Part Context

This part belongs to the Renesas clock buffer family, which provides low-jitter signal conditioning for digital systems. The 870S series typically addresses requirements for high-frequency clock distribution in complex electronic architectures where timing precision is critical for system performance.

Replacement Considerations

Consult the official Renesas replacement matrix for verified cross-references. Ensure any substitute part maintains the 1:4 ratio, 250 MHz frequency capability, and 32-VFQFN package dimensions for direct board compatibility.
