LMK00301ARHSR

Clock Buffers, Drivers Overview

The LMK00301ARHSR is a 3-GHz differential fanout buffer and level translator manufactured by Texas Instruments. It provides ten output channels capable of supporting LVPECL, LVDS, HCSL, and LVCMOS logic levels. The device operates within a supply voltage range of 3.15 V to 3.45 V and maintains a maximum propagation delay of 2.3 ns. Designed for high-frequency applications, it supports input frequencies up to 3.1 GHz with a duty cycle capability of up to 55%. The component is housed in a WQFN-48 package and functions within an operating temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Ten-output differential fanout buffer architecture
• Supports LVPECL, LVDS, HCSL, and LVCMOS output levels
• Maximum operating frequency of 3.1 GHz
• WQFN-48 surface-mount package

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• Differential signal buffering and translation
• Telecommunications infrastructure timing systems

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'ARHSR' against official Texas Instruments documentation to confirm tape-and-reel packaging and commercial grade specifications. Ensure compatibility with standard SMD/SMT assembly processes and check moisture sensitivity ratings prior to soldering.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential input requires expansion into ten distinct output paths with mixed logic level support. Confirm that the required output voltage levels (LVPECL, LVDS, etc.) align with the system's power rails and that the 3.15 V to 3.45 V supply constraint fits the design budget.

Clock Buffers, Drivers Part Context

This part belongs to the LMK00301 family of ultra-low additive jitter differential clock buffers. It shares functional similarities with variants such as the LMK00301SQ/NOPB and LMK00301ARHST, differing primarily in packaging style and manufacturing lot specifications rather than core electrical performance.

Clock Buffers, Drivers Replacement Considerations

Direct substitutes include LMK00301ARHST and LMK00301SQX/NOPB. Verify pin-to-pin compatibility and ensure that any alternative variant maintains the same 10-output configuration and 3.1 GHz frequency limit.
