ADF4356 Overview
The ADF4356 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6800 MHz. The ADF4356 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz.
