LMK00105SQE/NOPB

Clock Buffers, Drivers Overview

The LMK00105SQE/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 logic levels, including LVCMOS, LVDS, LVPECL, HCSL, and CML. The device provides ten LVCMOS outputs with a maximum operating frequency of 200 MHz. It operates within a supply voltage range of 2.375 V to 3.45 V and draws approximately 20 mA of quiescent current. Packaged in a 32-pin WQFN (WQFN-32) format, it supports surface-mount installation and functions reliably across a temperature range of -40°C to +85°C.

Clock Buffers, Drivers Feature Summary

• Universal input supporting LVCMOS, LVDS, LVPECL, HCSL, and CML signals
• Ten LVCMOS outputs for high-fanout clock distribution
• Ultra-low jitter performance optimized for precision timing applications
• Single 3.3V nominal supply operation with wide input voltage tolerance

Clock Buffers, Drivers Applications

• Clock distribution networks requiring low skew and jitter
• Level translation between different logic families in mixed-signal systems
• High-speed data acquisition and processing systems
• Telecommunications infrastructure timing circuits

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'SQE' against the manufacturer's latest documentation to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint for the WQFN-32 package. Confirm RoHS compliance status through official datasheets or component certificates prior to integration into regulated assemblies.

Clock Buffers, Drivers Selection Notes

Select this component when a single universal input must drive multiple LVCMOS loads with minimal jitter degradation. Compare output count and input flexibility against alternatives like the LMK00101 if fewer outputs are sufficient. Verify that the 200 MHz maximum frequency meets the system clock requirements and that the WQFN-32 thermal characteristics suit the enclosure design.

Clock Buffers, Drivers Part Context

This part belongs to the LMK0010x family of ultra-low jitter buffers from Texas Instruments. It serves as a specialized interface solution for converting diverse input clock sources into clean LVCMOS signals. Related variants include the LMK00101 and LMK00105 without the 'E' suffix, which may differ in packaging or testing criteria.

Clock Buffers, Drivers Replacement Considerations

The LMK00105SQ/NOPB is listed as a parameter-equivalent alternative. Verify pinout compatibility and electrical specifications before substitution. Other family members like the LMK00101 offer similar functionality but with different output counts.
