The LMX2594 from Texas Instruments is a high-performance, wideband RF synthesizer capable of generating frequencies from 10 MHz to 15 GHz. This device eliminates the need for internal doublers and sub-harmonic filters. It boasts a figure of merit of -236 dBc/Hz and high phase detector frequency, enabling very low in-band noise and integrated jitter.
Key electrical specifications include -110 dBc/Hz phase noise at a 100-kHz offset with a 15-GHz carrier and 45-fs rms jitter at 7.5 GHz. The synthesizer supports a 32-bit fractional-N divider, a 400-MHz integer mode phase detector frequency, and a 300-MHz fractional mode phase detector frequency. It operates from a single 3.3-V power supply and has a typical current consumption of 340 mA.
The LMX2594 supports advanced features such as synchronization of output phase across multiple devices, SYSREF generation with 9-ps resolution programmable delay, and frequency ramp/chirp generation for FMCW applications. Its VCO calibration speed is less than 20 µs.
Packaged in a 6 mm x 6 mm VQFN (RHA) package, the LMX2594 is designed for surface mounting. The operating temperature range is -40°C to 85°C.
