詳細說明
The LMX2594RHAR is a versatile and high-performance wideband synthesizer, offering a wide frequency range from 10 MHz to 15 GHz without the need for internal doubling. This eliminates the requirement for sub-harmonic filters, simplifying the design process. With an impressive PLL figure of merit of –236 dBc/Hz and a high-phase detector frequency, the LMX2594 achieves low in-band noise and integrated jitter, ensuring excellent signal quality. Its high-speed N-divider minimizes spurs by omitting a pre-divider, further enhancing performance. Additionally, the programmable input multiplier helps to reduce integer boundary spurs, providing a cleaner output signal
