Five, the introduction of the chip:
ADF4350/ADF4351 combined with external loop filter and external reference frequency, the fractional N frequency synthesizer or integer N frequency synthesizer with phase locked loop (PLL) frequency synthesizer can be realized.
ADF4350/ADF4351 has an integrated voltage controlled oscillator (VCO), whose fundamental output frequency range is from 2200 MHz to 4400 MHz. In addition, by using the 1/2/4/8/16 frequency divider circuit, the user can generate the RF output frequency as low as MHz 35Mhz/137.5. For applications that require isolation, the RF output level can be muted. Mute function can be controlled by pin, and can also be controlled by software. At the same time to provide auxiliary RF output, and can turn off when not used.
