The ADF4153 is a fractional-N frequency synthesizer that implements local oscillators in the upconversion and downconversion. The product features an RF bandwidth of up to 4 GHz, a power supply of 2.7 V to 3.3 V, extended tuning voltage, programmable fractional modulus, programmable charge pump currents, a 3-wire serial interface, analog and digital lock detect, power-down mode, and pin-compatibility with ADF4110/ADF4111/ADF4112/ADF4113 and ADF4106. It is suitable for applications such as CATV equipment, base stations for mobile radio, wireless handsets, wireless LANs, and PMR communications test equipment.
The ADF4153 fractional‑N frequency synthesizer implements a low‑noise digital phase‑frequency detector, programmable charge pump, and reference divider to generate local oscillators for wireless receivers and transmitters. It can be used with an external loop filter and VCO to form a complete PLL.
Key features include a 0.5‑4 GHz RF input range, 2.7‑3.3 V power supply, programmable fractional modulus, 3‑wire serial interface, lock‑detect outputs, and automotive‑qualified versions (Y version). The device is pin‑compatible with several Analog Devices synthesizers and supports low‑power sleep mode.

The device accepts RF input frequencies from 0.5 GHz up to 4.0 GHz (min/max).
It operates from a 2.7 V to 3.3 V supply for both AVop and DVpp pins.
The Y version is rated for –40 °C to +125 °C operation.
The TSSOP version uses a 16‑lead thin‑shrink package.
