ADF4007BCPZ

The ADF4007BCPZ is Analog Devices’ high-performance PLL-based frequency synthesizer. It supports both fractional-N and integer-N operation to generate RF frequencies with fine resolution and low phase noise, programmable via a serial (SPI) interface. The device uses a reference clock and a feedback/digital divider (modulus) to synthesize the desired output; it includes a programmable prescaler (for broad output ranges) and an internal phase detector and charge pump. External components required: a reference oscillator, a VCO (or VCO-based loop) and a loop filter. The ADF4007BCPZ is typically used in wireless transceivers, RF front-ends, radar, and test equipment where precise, tunable RF synthesis is needed. It comes in the BCPZ package from Analog Devices.
