Texas Instruments LMX2581 Wideband Frequency Synthesizer 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. They 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 the fractional mode, the denominator and the modulator order are programmable and can be configured with dithering as well.
