LMK00301SQE/NOPB

Clock Buffers, Drivers Overview

The LMK00301SQE/NOPB is a high-performance clock buffer and level translator manufactured by Texas Instruments. It features a single circuit with a 3:11 input-to-output ratio, supporting maximum frequencies of 3.1 GHz for both input and output signals. The device accepts multiple input logic standards including CML, HCSL, HSTL, LVDS, LVPECL, SSTL, and crystal inputs. Outputs are configurable to HCSL, LVCMOS, LVDS, or LVPECL levels. It operates on a supply voltage range of 3.15 V to 3.45 V with a typical operating current of 13.5 mA. The component is housed in a 48-WQFN package with exposed pad and functions within an industrial temperature range of -40°C to +85°C.

Clock Buffers, Drivers Procurement Notes

Verify the specific suffix code against the manufacturer's latest documentation to confirm pinout and electrical characteristics. The 'SQE' designation indicates a specific tape and reel packaging configuration. Confirm moisture sensitivity level (MSL 3) handling requirements prior to assembly. Ensure the ordering part number matches the exact package variant required for the PCB footprint.

Clock Buffers, Drivers Selection Notes

Select this component when a single input source must drive up to eleven outputs with varying logic levels. Verify that the system power supply remains within the 3.15 V to 3.45 V range to ensure optimal performance. Consider the 48-WQFN thermal pad requirements for adequate heat dissipation. Compare input/output voltage swing requirements against the supported HCSL, LVDS, and LVPECL options to determine necessary termination resistors.

Clock Buffers, Drivers Part Context

This device belongs to the LMK00301 family of low-jitter clock buffers. It serves as a versatile interface solution for converting and distributing high-frequency clock signals across mixed-voltage domains. The NOPB suffix indicates lead-free construction compliant with RoHS directives. It is distinct from other LMK series parts by its specific 3:11 ratio and broad input/output flexibility.

Clock Buffers, Drivers Replacement Considerations

Direct replacements within the same family include LMK00301SQX/NOPB, which shares identical electrical specifications but may differ in packaging quantity or reel type. Verify pin-to-pin compatibility before substitution. Other LMK series devices offer different input/output ratios and should be evaluated based on specific channel count requirements.
