LMX2820 Description
The LMX2820 is a high-performance, wideband synthesizer that can generate any frequency in the range of 45 MHz to 22.6 GHz. The high performance PLL with figure of merit of 236 dBc/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.
