Description

The LMX2581 is a low noise wideband frequency synthesizer which integrates a delta-sigma fractional N PLL, multiple core VCO, programmable output divider, and two differential output buffers.

The VCO frequency range is from 1880 to 3760 MHz and can be sent directly to the output buffers or divided down by even values from 2 to 38. Each buffer is capable of output power from -3 to +12 dBm at 2700 MHz.

Integrated low noise LDOs are used for superior noise immunity and consistent performance.
