LMK00301ARHST

Clock Buffers, Drivers Overview

The LMK00301ARHST is a differential fanout buffer and level translator manufactured by Texas Instruments. It features ten outputs capable of supporting frequencies up to 3.1 GHz. The device operates within a supply voltage range of 3.15 V to 3.45 V and consumes approximately 20 mA of operating current. It accepts multiple input levels, including LVPECL, LVDS, CML, SSTL, HSTL, and HCSL, while providing flexible output configurations such as LVPECL, LVDS, HCSL, and LVCMOS. Packaged in a 48-pin WQFN, it functions reliably across an industrial temperature range from -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Supports maximum input and output frequencies of 3.1 GHz
• Provides 10 differential outputs with configurable logic levels
• Accepts diverse input standards including CML, SSTL, HSTL, LVDS, and LVPECL
• Operates on a single 3.3 V supply with low power consumption

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Level translation between different logic families
• Fanout buffering for high-frequency signal integrity

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'ARHST' corresponds to the tape-and-reel packaging format intended for surface-mount assembly. Confirm that the component meets RoHS compliance requirements for the target market. Ensure handling procedures account for moisture sensitivity classification during storage and reflow soldering processes.

Clock Buffers, Drivers Selection Notes

Select this component when a single input requires distribution to ten distinct loads at frequencies exceeding 3 GHz. It is suitable for designs requiring conversion between various differential and single-ended signaling standards without external discrete components. Consider the 48-WQFN package constraints for thermal management and PCB layout density.

Clock Buffers, Drivers Part Context

This part belongs to the LMK00301 series of clock buffers. It serves as a specialized solution for maintaining signal integrity in high-speed digital systems. The device integrates level translation capabilities directly into the fanout buffer architecture, reducing bill-of-materials complexity compared to using separate translators.

Clock Buffers, Drivers Replacement Considerations

LMK00301ARHSR shares identical electrical specifications but differs in packaging configuration. LMK00301SQX/NOPB offers similar functionality but specifies 11 outputs and slightly different input/output level options. Verify pin compatibility and parameter alignment before substitution.
