ADF4153YRUZ - 4 GHz Fractional-N PLL | Analog Devices
部品番号: ADF4153YRUZ ✓ 生産中ADF4153YRUZ 概要
A fractional-N frequency synthesizer belongs to the PLL family of clock-generation and timing integrated circuits. A PLL locks the phase and frequency of an output signal to a reference source, while a fractional-N PLL divides the feedback count through controlled fractional feedback to achieve finer frequency steps. This combination places the ADF4153YRUZ within the hierarchy of phase-locked loop, frequency synthesizer, clock and timing IC, and semiconductor.
The device combines a low-noise digital phase-frequency detector, a precision charge pump, a programmable reference divider, programmable fractional modulus, and programmable charge-pump current. A separate VP connection permits an extended tuning-voltage range. These features support adjustable loop behavior and help engineers balance phase noise, reference-divider frequency, tuning range, and lock performance according to the RF requirements of the receiving or transmitting chain.
The ADF4153 is intended for RF local-oscillator generation where a stable reference must be translated into an accurately programmable output frequency. Its 4 GHz RF bandwidth covers applications from wireless communications and test equipment to instrumentation requiring programmable RF clocks. The digital phase-frequency detector and precision charge pump form the core feedback loop, while the fractional-N mechanism allows fine frequency offsets without relying only on integer feedback ratios.
Typical uses include wireless receiver and transmitter local oscillators, microwave upconversion and downconversion sections, communications test equipment, and frequency-generation subsystems. Its programmable fractional modulus is particularly useful when the required output frequency must be synthesized with fine resolution while maintaining a controlled relationship to an external reference.
When designing the circuit, use the manufacturer pin-description table and recommended decoupling values to assign pins and place components. Account for loop-filter design, reference-divider selection, charge-pump current, and VCO gain when calculating lock time and phase-noise performance. The programming interface and register definitions should be implemented according to the ADF4153 datasheet and its listed digital-control requirements.
This product record combines the manufacturer's device description, distributor identification, package information, RF bandwidth, power-supply requirement, and temperature-grade details into an engineering-oriented reference. It also organizes compatible-part considerations, application guidance, comparison points, and practical design cautions so that the ADF4153YRUZ can be evaluated for RF synthesis designs before schematic capture.

主な用途
ADF4153YRUZ の用途: 6 件s: Wireless Receiver Local Oscillator, Wireless Transmitter Upconversion, Microwave Downconversion, Communications Test Equipment, RF Instrumentation Signal Source, Frequency-Selective Measurement System.
Wireless Receiver Local Oscillator
The ADF4153YRUZ fits a wireless receiver local-oscillator block because it synthesizes programmable RF frequencies up to 4 GHz using a fractional-N PLL architecture. Its low-noise digital phase-frequency detector and precision charge pump support the feedback process, while programmable fractional modulus permits fine frequency steps relative to the reference. The 3.3 V supply and 16-TSSOP package also support compact radio designs. Design the loop filter from the selected prescaler, divider, charge-pump current, and VCO gain, then verify phase noise and lock performance across the required receiver bands.
おすすめ
Wireless Transmitter Upconversion
In a wireless transmitter, the ADF4153YRUZ can generate the programmable local-oscillator reference used by an upconversion chain. Its RF bandwidth to 4 GHz covers a broad range of microwave signal paths, and the fractional-N modulus lets the designer obtain fine tuning increments without integer-only division ratios. The separate VP connection supports an extended tuning-voltage range at the associated VCO. Engineer the loop for the required lock time, phase noise, and reference spurs while confirming that the VCO tuning range and output power match the transmitter architecture.
おすすめ
Microwave Downconversion
The ADF4153YRUZ is appropriate for programmable local-oscillator generation ahead of a microwave downconverter. A 4 GHz fractional-N output allows a receiver to translate selected RF channels into a lower intermediate-frequency band, while programmable charge-pump current and divider controls support loop optimization. The 16-TSSOP format keeps the synthesizer compact beside the mixer and RF chain. Validate phase-noise translation through the complete downconversion system, and account for image rejection, mixer isolation, reference purity, and acquisition time when selecting loop bandwidth.
おすすめ
Communications Test Equipment
Programmable RF test equipment can use the ADF4153YRUZ to generate controllable local-oscillator signals for receiver and transmitter characterization. Fractional-N operation provides selectable frequencies with fine resolution, while the reference divider, charge-pump settings, and fractional modulus permit extensive configuration through the digital control interface. With a 3.3 V supply and 4 GHz bandwidth, the device fits compact instrument subsystems. Design the loop for fast settling when changing channels, and verify long-term phase noise, reference-to-output isolation, and spurious-signal levels with the intended test specifications.
おすすめ
RF Instrumentation Signal Source
The ADF4153YRUZ can serve as the programmable RF synthesis element in an instrumentation signal source. Its 4 GHz upper RF bandwidth and fractional-N architecture permit multiple output frequencies to be derived from one stable reference, while the programmable charge pump and reference divider help tailor the PLL loop for different operating modes. The 16-TSSOP package supports compact board layouts in multi-channel or portable instruments. Account for the associated VCO's tuning sensitivity and ensure that supply noise, reference phase noise, isolation, and output filtering meet the instrument's amplitude-accuracy requirements.
おすすめ
Frequency-Selective Measurement System
A frequency-selective measurement system can use the ADF4153YRUZ to create an adjustable local-oscillator reference for synchronized excitation and demodulation. Fractional-N modulation gives the designer a programmable relationship between the reference and the selected measurement frequency, while the low-noise phase-frequency detector supports coherent generation. The 4 GHz bandwidth makes the part relevant to many RF and microwave test paths. Set the loop bandwidth according to sweep-rate, phase-noise, and settling requirements, then check reference coupling, crosstalk, and spur behavior across neighboring channels.

設計ノート
Do not treat a shared TSSOP outline as proof of interchangeability. Confirm the complete 16-pin assignment, supply requirements, reference-input limits, tuning-voltage behavior, and digital-control implementation for every proposed replacement. In particular, verify that the separate VP connection is implemented identically and that a higher maximum frequency does not alter the register map or recommended application circuit.
Use the manufacturer reference layout as the starting point for the reference, charge-pump, loop-filter, power, and digital-control connections. Keep the reference path short, isolate noisy switching nodes from the phase detector, and place decoupling capacitors at the appropriate supply pins. Route programming signals away from the sensitive reference and feedback nodes to reduce coupling-induced phase-noise and spurious-signal degradation.
The PLL loop must be evaluated with the actual reference noise, VCO gain, divider settings, charge-pump current, and loop filter. Simulate both acquisition time and steady-state phase noise, then measure reference spurs and output stability over temperature and supply variation. A fractional-N architecture can improve frequency resolution, but spur performance remains dependent on loop bandwidth, filtering, and layout.
