The LMX2594 RF PLL with VCO offers the following features and benefits to make it easier for engineers to design a high-frequency RF signal chain:
- Best noise performance: The LMX2594 features the industry’s lowest normalized PLL noise floor of -236 dBc/Hz and 1/f of -129 dBc/Hz, enabling designers to improve radio sensitivity and spectral resolution.
- Design simplicity: The integrated VCO operates at up to 15 GHz, eliminating the need for expensive, complex on-board filters to remove subharmonics. The LMX2594 also automatically generates a frequency ramp, eliminating up to five devices typically required to perform this function for radar applications and enabling compact solutions.
- Phase synchronization: System designers can easily synchronize the output of all on-board PLLs, saving design time for implementing multiple-input/multiple-output (MIMO), beamforming in their applications.
- JESD204B support: The LMX2594 enables simultaneous generation of gigahertz frequency sampling and JESD204B SYSREF timing signals.
The new ADC and PLL with VCO expand TI’s portfolios of RF sampling data converters and wideband clock and timing devices. Complete a JESD204B-compliant design with the ADC12DJ3200 and LMX2594 to simplify clocking architecture, synchronization and data capture.
Availability and pricing
Both the new ADC and PLL are available today from the TI store and authorized distributors. The ADC12DJ3200 comes in a flip-chip ball-grid array (FCBGA) package and is priced in 100-unit quantities at US$1,920.00. The LMX2594 comes in a very thin quad flat no-lead (VQFN) package and is priced at US$41.00 in 1,000-unit quantities.
