ADF4383 Fractional-N Phased-Locked Loops (PLLs)

Analog Devices ADF4383 Fractional-N Phased-Locked Loops (PLLs) are a high-performance, ultra-low jitter, fractional-N phased-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO). These are ideally suited for local oscillator (LO) generation for 5G applications 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 ADF4383 can generate frequencies in a fundamental octave range of 10GHz to 20GHz, eliminating the need for subharmonic filters. The output dividers on the ADF4383 allow a complete output frequency range to be generated from 625MHz to 20GHz.
