APPLICATIONS
The ADF4372 has an integrated VCO with a fundamental output frequency ranging from 4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to a divide by 1, 2, 4, 8, 16, 32, or 64 circuit that allows the user to generate radio frequency (RF) output frequencies as low as 62.5 MHz at RF8x.
