The 2.5 GHz maximum operating frequency sets the upper bound for the VCO input. In practice, this part handles L-band and lower S-band synthesizers — common in satellite downconverters, microwave links, and wireless infrastructure local oscillators. The divider/multiplier block (Yes/No) lets you scale the feedback path, but the VCO tuning range must stay within the 2.5 GHz ceiling.

Frequently asked questions
Does LMX2310USLDX replace LMX2310?
The LMX2310USLDX is an active PLLatinum™ frequency synthesizer. The evidence does not list an LMX2310 variant, so a direct replacement claim cannot be confirmed from this record.
