The ADF435x synthesizers include an integrated VCO with a 2200MHz to 6800MHz fundamental output frequency. The VCO frequency can be divided by 1, 2, 4, 8, 16, 32, or 64 circuits. This design enables the designer to generate RF output frequencies as low as 35MHz. The ADF435x synthesizers operate using 3V to 3.6V analog and digital power supplies. The synthesizers also use 4.75V to 5.25V charge pumps and VCO supplies.
If an application requires isolation, designers can mute the RF output stage. Designers can also control the on-chip registers using a simple 3-wire interface.
The ADF435x synthesizers are ideal for wireless infrastructure, point-to-point/point-to-multipoint microwave links, satellites/VSATs, test equipment/instrumentation, and clock generation.
