Chip introduce:
ADF4351 combined with external loop filter and external reference frequency when using, it can realize the decimal N points frequency or integer N frequency and phase lock loop (PLL) frequency synthesizer.
 ADF4351 have an integrated voltage controlled oscillator (VCO), its fundamental wave output frequency range to 2200 MHz to 4400 MHz.In addition, the use of 1/2/4/8/16 points frequency circuit, the user can generate as low as 35 MHz / 137.5 MHz RF output frequency.For the isolation of application, the RF output stage can be mute.Mute function can be controlled by pin, can also be controlled by software.At the same time provide auxiliary RF output, and can be shut off when not in use.

Specifications:
- This version is ADF4351
- The output frequency range: 35 MHz to 4400 MHz
- Fractional N points frequency synthesizer and integer N frequency synthesizer
