The ADF4372 is a microwave wideband synthesizer that operates from 62.5 MHz to 16 GHz. It 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. The wideband microwave voltage controlled oscillator (VCO) design allows frequencies from 62.5 MHz to 16 GHz to be generated. 

The ADF4372 has an integrated VCO with a fundamental output frequency ranging from 4000 to 8000 MHz.The VCO frequency is also connected to a divide by 1, 2, 4, 8, 16, 32, or 64 circuit that allows the user to generate output frequencies as low as 62.5 MHz at RF8x. A frequency multiplier at RF16x can be used to generate a signal from 8 GHz to 16 GHz. RFAUX8x duplicates the frequency range of RF8x or permits direct access to the VCO output.

The ADF4372 operates with analog and digital power supplies ranging from 3.15 V to 3.45 V, and 5 V for the VCO power supply. It is available in a 7 x 7 mm, 48-terminal LGA package and is ideal for aerospace, clock generation, wireless infra and test equipment applications.
