Bucles con bloqueo por fases (PLL) de N fraccional ADF4382x

Analog Devices ADF4382x Fractional-N Phased-Locked Loop (PLL) is a high-performance, ultra-low jitter, fractional-N phased-locked loop (PLL). It has an integrated voltage-controlled oscillator (VCO) ideally suited for the local oscillator (LO) generation for 5G or data converter clock applications. The high-performance PLL has a figure of merit of -239dBc/Hz, low 1/f noise, and a high PFD frequency of 625MHz in integer mode that can achieve ultra-low in-band noise and integrated jitter. The ADF4382x can generate frequencies in a fundamental octave range of 11.5GHz to 21GHz, eliminating the need for subharmonic filters. The divide by two and four output dividers on the ADF4382x allow frequencies to be generated from 5.75GHz to 10.5GHz and 2.875GHz to 5.25GHz, respectively.
