LMX2581SQE/NOPB - TI Function Overview

The LMX2581SQE/NOPB is a low noise wideband Frequency Synthesizer that 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 3760MHz 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 +12dBm at 2700MHz. Integrated low noise LDOs are used for superior noise immunity and consistent performance. This synthesizer is a highly programmable device and it enables the user to optimize its performance. In fractional mode, the denominator and the modulator order are programmable and can be configured with dithering as well. The user also has the ability to directly specify a VCO core or entirely bypass the internal VCO. Finally, many convenient features are included such as power down, Fastlock, auto mute and lock detection.
