LMK00304SQ/NOPB

Clock Buffers, Drivers Overview

The LMK00304SQ/NOPB is a differential clock buffer and level translator manufactured by Texas Instruments. It operates with a supply voltage range of 3.15 V to 3.45 V and supports maximum input and output frequencies up to 3.1 GHz. The device features five LVPECL outputs and accepts an LVPECL input signal. It exhibits a maximum propagation delay of 2.3 ns and draws a typical operating supply current of 13.5 mA. The component is housed in a 32-pin WQFN package and is rated for operation between -40°C and +85°C.

Clock Buffers, Drivers Feature Summary

• Supports differential clock frequencies up to 3.1 GHz
• Provides five LVPECL outputs from an LVPECL input
• Low power consumption with 13.5 mA typical supply current
• Available in a compact 32-WQFN package

Clock Buffers, Drivers Applications

• High-speed data converter clock distribution
• Telecommunications infrastructure timing
• Test and measurement equipment synchronization

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix 'SQ' against the manufacturer's datasheet to confirm the exact temperature grade and packaging variant. Confirm RoHS compliance status through official documentation, as indicated by the 'NOPB' designation. Ensure handling procedures account for moisture sensitivity classification during storage and assembly.

Clock Buffers, Drivers Selection Notes

Select this component when a single differential input must drive multiple LVPECL loads at frequencies approaching 3.1 GHz. Compare the 13.5 mA current draw against system power budgets. Verify that the 32-WQFN footprint aligns with the PCB layout constraints and thermal requirements of the design.

Clock Buffers, Drivers Part Context

This part belongs to the LMK00304 series of clock buffers. Related variants include the LMK00304SQX/NOPB, which shares identical electrical specifications but utilizes tape-and-reel packaging instead of cut tape or other reel formats. The series focuses on high-frequency signal integrity for precision timing applications.

Clock Buffers, Drivers Replacement Considerations

The LMK00304SQX/NOPB serves as a direct functional equivalent with identical pinout and electrical parameters, differing primarily in shipping packaging configuration.
