Product details

The 2.79 GHz upper frequency covers L-band, S-band, and the lower portion of C-band allocations. The integrated VCO eliminates an external resonator. The 2:2 input-to-output ratio means two clock inputs can be routed to two synthesizer paths within the same die.

The ROHS3 compliance covers the latest EU exemption updates.

Frequently asked questions

What is the frequency range of LMX2531LQ2570E?

The maximum output frequency is 2.79 GHz. The lower bound depends on the VCO tuning range and divider settings; the datasheet covers the full lock range.

Is LMX2531LQ2570E compatible with 2.8V supply?

Yes, the supply voltage range is 2.8V to 3.2V, so a 2.8V rail is within spec.
