Five, chip introduction:

ADF5355 combines the external loop filter and the external reference frequency when it can be implemented with fractional N frequency division or integer N frequency division phase-locked loop (PLL) frequency synthesizers. The microwave broadband VCO design allows the implementation of an RF (RF) output at 6.8 GHz to 13.6 GHz operating frequency. A series of frequency dividers with other frequency outputs can achieve operating frequencies of 54 MHz to 6800 MHz.

The ADF5355 has an integrated VCO with a fundamental output frequency range of 3400 MHz to 6800 MHz. In addition, the VCO frequency can be divided into 1, 2, 4, 8, 16, 32 or 64 frequency division, so that the user can produce an output frequency of RF as low as 54 MHz. For applications requiring isolation, the RF output stage can mute. The mute function can be controlled either by pin or by software.

All on-chip registers are controlled by a simple three wire interface. The ADF5355 employs 3.15 V to 3.45 V analog and digital power supplies, and operates from 4.75 V to 5.25 V charge pump and VCO power supplies. In addition, ADF5355 has built-in hardware and software power saving mode.
