The base product number is LMK00306, and the /NOPB suffix indicates a lead-free (RoHS-compliant) finish — no special handling or exemption paperwork required.
If you are filling a prototype run or a production build, send the RFQ with your target quantity and required delivery window.
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.
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.
