What re the main differences between LMX2581 and LMX2581E?

Is it ONLY the output frequency of 3800M Vs 3760M?

These devices are very similar and the only difference is the output frequency.

For the LMX2581E, we shifted VCO4 core slightly upwards to be able to achieve 3800 MHz.

Eli,

Also for new designs, consider the LMX2572. It is not pinout or program compatible, but it is lower current, lower spurs, and better PLL noise.
Also it has some added features.
