LMK00105SQ/NOPB

Clock Buffers, Drivers Overview

The LMK00105SQ/NOPB is an ultra-low jitter LVCMOS fanout buffer and level translator manufactured by Texas Instruments. It features a universal input capable of accepting various clock signals, including LVDS, HCSL, LVPECL, CML, and single-ended sources. The device provides ten LVCMOS outputs with configurable drive strength. Key electrical parameters include a maximum operating frequency of 200 MHz, a propagation delay of 2.8 ns maximum, and a supply voltage range of 2.375 V to 3.45 V. It operates within a temperature range of -40°C to +85°C and is housed in a WQFN-32 package.

• FPGA and ASIC clock buffering
• Telecommunications infrastructure timing
• Test and measurement equipment

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix (SQE, SQX, or SQ) against the required packaging format, such as tape and reel or cut tape, as these affect logistics but not function. Confirm RoHS compliance status via the manufacturer's official documentation before procurement. Ensure the ordering part number matches the exact package variant needed for the PCB footprint.

Clock Buffers, Drivers Selection Notes

Select this component when a universal input buffer is required to interface between different clock standards and LVCMOS logic. Verify that the 200 MHz maximum frequency meets the system requirements. Check if the ten-output configuration aligns with the design needs; otherwise, consider the LMK00101 for fewer outputs. Ensure the 2.375 V to 3.45 V supply range is compatible with the system power rails.

Clock Buffers, Drivers Part Context

This device belongs to the LMK0010x family of ultra-low jitter fanout buffers from Texas Instruments. It shares functional similarities with the LMK00101 but offers a higher output count. The NOPB suffix indicates lead-free construction and compliance with RoHS directives. It is designed to replace older generation buffers requiring external level translation components.

Clock Buffers, Drivers Replacement Considerations

The LMK00101SQ/NOPB serves as a direct alternative for designs requiring fewer than ten outputs. For applications needing more outputs, the LMK00105 series variants with different suffixes may be considered. Verify pin-to-pin compatibility and electrical specifications before substitution.
