LMX2595 Wideband RF Synthesizer

Texas Instruments LMX2595 Wideband RF Synthesizer can generate any frequency from 10MHz to 19GHz. An integrated doubler is used for frequencies above 15GHz. The high-performance PLL with the figure of merit of –236dBc/Hz and high-phase detector frequency can attain very low in-band noise and integrated jitter. The high-speed N-divider has no pre-divider, thus significantly reducing the amplitude and number of spurs. There is also a programmable input multiplier to mitigate integer boundary spurs. The LMX2595 allows users to synchronize the output of multiple devices and also enables applications that need a deterministic delay between input and output. A frequency ramp generator can synthesize up to 2 segments of a ramp in an automatic ramp generation option or a manual option for maximum flexibility. The fast calibration algorithm allows changing frequencies faster than 20 µs. The LMX2595 adds support for generating or repeating SYSREF (compliant to JESD204B standard) making it an ideal low-noise clock source for high-speed data converters.
