Radio Frequency Synthesizer Synchronizes the Output of all Onboard PLLs

 PDF

Mouser Electronics, Inc., is now stocking the LMX2594 wideband PLLatinum radio frequency (RF) synthesizer from Texas Instruments (TI). Part of TI’s PLLatinum series, the LMX2594 enables designers to easily synchronize the output of all onboard PLLs, saving design time for multiple-input/multiple-output (MIMO), beamforming, and other applications.

The TI LMX2594 wideband PLLatinum RF synthesizer, available from Mouser Electronics, is a high-performance wideband phased-locked loop (PLL) RF synthesizer with an integrated voltage-controlled oscillator (VCO) that can generate any frequency from 10 MHz to 15 GHz without using an internal frequency doubler, eliminating the need for complex onboard filters to remove subharmonics. The device features best-in-class noise performance with one of the lowest normalized PLL noise floors (at -236 dBc/Hz and 1/f of -129 dBc/Hz), enabling designers to improve radio sensitivity and spectral resolution. Integrated ramp generation and LDOs further simplify the design process, eliminating up to five devices typically required to perform this function.

The LMX2594 device comes equipped with a 32-bit fractional divider that allows fine frequency selection and supports both fractional-N and integer-N modes. The device also offers 45 fs RMS jitter at 7.5 GHz, support for JESD204B SYSREF, phase synchronization and ramp generation to simplify high-performance microwave and millimeter-wave system design.

Target applications for the LMX2594 include 5G and millimeter-wave wireless infrastructures, test and measurement equipment, radar, MIMO, phased array antennas and beam forming, and high-speed data converter clocking applications. For development, Mouser also stocks the LMX2594EVM RF synthesizer evaluation module.
