ADF4116/ADF4117/ADF4118 are RF PLL frequency synthesizers with a frequency range of 550 MHz to 3.0 GHz, a power supply range of 2.7 V to 5.5 V, and extended tuning voltage capability in 3 V systems. They can be used to implement local oscillators (LO) in the upconversion and downconversion sections of wireless receivers and transmitters. These frequency synthesizers feature a low noise digital phase frequency detector (PFD), a precision charge pump, a programmable prescaler, digital lock detect, power-down mode, and fastlock mode.
The ADF4116/ADF4117/ADF4118 family are RF PLL frequency synthesizers designed for use as local oscillators in wireless transmitters and receivers. They integrate a low‑noise digital phase‑frequency detector, charge pump, programmable reference divider, A and B counters and a dual‑modulus prescaler, all controlled via a 3‑wire serial interface.
