Product details

Active lifecycle — no end-of-life watch needed

That means it can be specified into a new BOM without planning for a last-time-buy window, and it will be available through the independent distribution channel for production replenishment. The base product number is LMK00306, and the /NOPB suffix indicates a lead-free (RoHS-compliant) finish — no special handling or exemption paperwork required.

Sourcing this part for a BOM line

If you are filling a prototype run or a production build, send the RFQ with your target quantity and required delivery window.

Frequently asked questions

What is the closest functional equivalent to LMK00306SQE/NOPB?

The CDCLVP1204RGTR is a functional peer — it is a fanout buffer and multiplexer with LVPECL outputs, but its maximum frequency is 2.0 GHz versus the LMK00306's 3.1 GHz, and its input-to-output ratio is 2:4 versus 3:7. The LMK00306 covers a wider set of input standards and offers higher frequency headroom for PCIe Gen4/5 or 100G reference clocks.

What voltage supply does LMK00306SQE/NOPB require?

The supply range is 3.15 V to 3.45 V. A standard 3.3 V rail is within tolerance, but the narrow window means the rail must be well-regulated — check ripple from any switching converter feeding this buffer.
