LMX2572EVM: 6.4-GHz Low Power Wideband RF Synthesizer with Phase Synchronization and JESD204B Support


Features, Applications

TI's broad portfolio of PLLatinum® microwave phase locked loop (PLL) and synthesizer (PLL with integrated VCO) family offers the best choice for a variety of applications ranging from performance demanding industrial RADAR, make and test equipment, MC-GSM/FDD/TDD wireless base stations and repeaters to low power applications like Land Mobile Radio, USB powered test equipment and wireless microphones. New high performance, high frequency synthesizers are designed targeting applications in the microwave and millimeter-wave (mm-wave) region including 5G base stations and wireless testers.

Synchronize multiple PLLs Remove integer boundary spurs with easy programming Generate SYSREF with fine delay adjustment for clocking JESD204B compliant data converters Generate frequency ramps Support for FSK modulation Integrated LDOs for easy power supply design

Normalized Phase Noise (dBc/Hz) Current Consumption (mA)
Feature rich, high performance products for the most performance demanding applications

Texas Instruments PLL plus integrated VCO have Industry leading performance with a PLL figure of merit (1 Hz carrier, 1 Hz phase detector frequency) down to -236 dBc/Hz, flicker noise down to -129 dBc/Hz (1 GHz carrier, 10 kHz offset) and outstanding VCO phase noise. They are the best choice for applications that demand the highest performance. By integrating multiple VCOs going to 15 GHz LMX2594, TI sets a new benchmark for SiGe PLLs with integrated VCOs. LMX2594 make it easy to synchronize the output phase of multiple devices in a system even when the PLL is used in fractional mode. Once the output phases of the fractional PLLs are aligned, it is possible to adjust the phase of each device individually. This makes Multiple Input, Multiple Output (MIMO) and beam-forming applications easier to implement.
