The ADF4252BCP is a dual fractional-N/integer-N frequency synthesizer from Analog Devices, designed for implementing local oscillators in wireless transmitters and receivers. It combines a low noise digital phase frequency detector (PFD), precision charge pump, and programmable reference divider.
The RF synthesizer features a Σ-Δ-based fractional interpolator for programmable fractional-N division, supporting frequencies up to 3.0 GHz. The IF synthesizer uses programmable integer-N counters, operating up to 1.2 GHz. The device operates from a 2.7V to 3.3V power supply, with a separate V_P pin allowing extended tuning voltage up to 5V.
The ADF4252BCP includes a programmable dual modulus prescaler, programmable charge pump currents, digital lock detect, and power-down mode. It communicates via a 3-wire serial interface. The device is available in a 24-lead LFCSP package and is suitable for base stations, wireless handsets, WLANs, communications test equipment, and CATV equipment.
The operating voltage range is 2.7V to 3.3V.
