LMK00301SQ/NOPB

Clock Buffers, Drivers Overview

The LMK00301SQ/NOPB is a 3.1-GHz differential clock buffer and level translator manufactured by Texas Instruments. It features 11 outputs supporting HCSL, LVDS, and LVPECL signaling levels. The device operates on a single 3.15-V to 3.45-V supply with a typical operating current of 13.5 mA. It is housed in a 48-WQFN package with exposed pad, rated for operation between -40°C and +85°C. The component accepts HCSL, LVDS, or LVPECL inputs and provides low additive RMS jitter performance suitable for high-speed data converter clocking.

Clock Buffers, Drivers Feature Summary

• Supports up to 3.1 GHz maximum input and output frequency
• Provides 11 differential outputs with configurable HCSL, LVDS, or LVPECL levels
• Accepts multiple input formats including HCSL, LVDS, and LVPECL
• Operates within a 3.15 V to 3.45 V voltage range

Clock Buffers, Drivers Applications

• Clock distribution for high-speed analog-to-digital converters (ADCs)
• Jitter attenuation in precision measurement systems
• Fan-out buffering for multi-channel synchronization architectures

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix code against the manufacturer datasheet to confirm temperature grade and packaging configuration. Ensure compatibility with the 48-WQFN footprint and thermal requirements during PCB layout. Confirm moisture sensitivity level handling procedures are followed prior to assembly.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential source requires expansion into multiple differential clocks with varying voltage levels. Compare additive jitter specifications against system phase noise budgets. Verify that the 3.3 V nominal supply aligns with the specified 3.15 V to 3.45 V operational window.

Clock Buffers, Drivers Part Context

This part belongs to the LMK00301 family of ultra-low noise clock buffers. Variants such as LMK00301SQX/NOPB and LMK00301SQE/NOPB share identical electrical characteristics but differ in reel quantities and tape-and-reel specifications. All variants maintain the same 48-WQFN pinout and functional behavior.

Clock Buffers, Drivers Replacement Considerations

LMK00301SQX/NOPB and LMK00301SQE/NOPB are electrically equivalent alternatives within the same series. Cross-reference package dimensions and thermal pad connections to ensure mechanical compatibility during substitution.
