ADF4116BRU - 550 MHz Integer-N RF PLL | Analog Devices
MPN： ADF4116BRU ✗ 停產ADF4116BRU 概覽
A frequency synthesizer is a clock-and-timing device that locks an output frequency to a stable reference. The ADF4116 family belongs to the broader RF PLL hierarchy: a phase-frequency detector and precision charge pump compare the divided output with a reference signal, while programmable counters determine the multiplication ratio. This architecture provides programmable frequency generation for RF upconversion, downconversion, modulation, and test equipment.
Key features identified in the verified manufacturer data include a 550 MHz maximum operating frequency, a 32/33 dual-modulus prescaler, a 5-bit A counter, a programmable B counter, selectable charge-pump currents, and digital lock detect. The device supports a 5.5 V power supply and a separate VP connection that can extend the tuning-voltage range in suitable 3 V systems. Its serial programming interface simplifies frequency, counter, prescaler, and power-state configuration.
Technically, the integer-N architecture uses a dual-modulus prescaler to synthesize many output frequencies from one reference source. The programmable A and B counters divide the prescaled RF signal, while the phase-frequency detector controls the charge-pump current applied to an external loop filter. Correct loop-filter design, reference stability, and RF layout determine practical phase noise and lock performance; the supplied search results do not provide complete phase-noise curves or timing values.
Typical uses include wireless receiver and transmitter local oscillators, upconversion and downconversion chains, industrial RF systems, instrumentation, and communication equipment. The 16-TSSOP package is compact and surface-mountable, but exposed-pad thermal details and exact pin names were not provided in the verified data.
When replacing this part, verify the complete ADF4116 datasheet pinout, counter limits, reference frequency, prescaler range, supply sequencing, and loop-filter requirements. The verified distributor result also identifies ADF4116BRUZ as the current production variant with identical electrical specifications and pin compatibility, but that claim is not treated as a manufacturer-confirmed drop-in substitute here.
This page combines the verified manufacturer and distributor records with engineering guidance, application context, and replacement caveats for engineers evaluating RF PLL layouts.

典型應用
ADF4116BRU 適用於 6 應用s: Wireless Receiver Local Oscillator, Wireless Transmitter Upconversion, Industrial RF Instrumentation, RF Downconversion Mixer, Frequency Reference Test Equipment, RF Communication Module.
Wireless Receiver Local Oscillator
The ADF4116BRU fits wireless receiver local-oscillator designs because the ADF4116 family is explicitly intended for local oscillators in the upconversion and downconversion sections of wireless receivers and transmitters. Its 550 MHz maximum operating frequency, programmable reference divider, programmable A and B counters, and 32/33 dual-modulus prescaler provide the frequency-generation core for converting a stable reference into the required LO frequency. The three-wire serial interface allows the system controller to program the operating ratio and monitor digital lock detect. In implementation, keep the reference and RF feedback paths short and controlled, because loop-filter selection and PCB parasitics strongly affect phase noise and lock performance.
推薦
Wireless Transmitter Upconversion
For wireless transmitter upconversion, the ADF4116BRU can synthesize the programmable local oscillator required by an RF signal chain. Analog Devices identifies the ADF4116 family for both transmitter and receiver upconversion sections, while the supplied device data confirms a 550 MHz maximum operating frequency and programmable RF prescaler. The integer-N architecture uses the low-noise digital phase-frequency detector, precision charge pump, programmable reference divider, and counters to close the loop around the RF feedback path. Designers should choose the prescaler, counter values, charge-pump current, and external loop filter as one system rather than treating the PLL as a fixed-frequency oscillator.
推薦
Industrial RF Instrumentation
The ADF4116BRU is suitable for industrial RF instrumentation that requires a programmable, reference-synchronized local oscillator. The 16-TSSOP surface-mount package supports compact instrument designs, while the three-wire serial interface allows a microcontroller or test controller to configure the frequency. The verified records do not provide complete phase-noise, reference-input, or output-power limits, so those parameters must be checked in the official data sheet before setting an instrumentation noise floor. Use a clean reference supply, a carefully designed loop filter, and short RF routing to avoid adding avoidable phase noise and modulation products.
推薦
RF Downconversion Mixer
The ADF4116BRU can support RF downconversion by generating the local-oscillator signal applied to a mixer or receiver front end. The ADF4116 family’s stated use in receiver downconversion, combined with its programmable counters and dual-modulus prescaler, allows the LO frequency to be derived from a common reference instead of using a fixed source. The 550 MHz maximum figure is a device ceiling, not a guarantee that every prescaler and counter combination is valid. Validate the frequency plan, reference ratio, lock range, loop bandwidth, and mixer interface against the official datasheet and the receiver’s phase-noise requirement.
推薦
Frequency Reference Test Equipment
The programmable ADF4116BRU architecture can be used in test equipment that derives multiple RF frequencies from one stable reference. Programmable reference division, A-counter and B-counter settings, selectable charge-pump currents, and digital lock detect make the device useful where a controller must configure a coherent LO and verify lock state. The supplied verified data does not specify settling time, phase-noise floors, or output power, so these characteristics must be measured or retrieved from the complete manufacturer data sheet. A controlled reference source and calibrated loop-filter implementation are essential for repeatable measurements.
推薦
RF Communication Module
The ADF4116BRU can serve as the programmable RF frequency-synthesis element in a communication module requiring a coherent local-oscillator reference. Its 32/33 dual-modulus prescaler and programmable counters support flexible frequency planning, while the three-wire serial interface permits digital control from a baseband processor. The verified manufacturer description specifically links the ADF4116 family to wireless receiver and transmitter local oscillators. Because exact reference-frequency limits, output-buffer characteristics, and phase-noise curves are absent from the supplied data, engineers should not finalize RF budgets without consulting the official data sheet and evaluating the actual reference and loop-filter implementation.

設計說明
Keep the reference input, phase-frequency detector path, charge-pump output, loop-filter components, and RF feedback route compact and tightly controlled. The supplied data confirms a precision charge pump and programmable counters but does not provide a complete layout or phase-noise specification, so follow the official ADF4116 reference layout and use a continuous ground reference. Avoid routing the sensitive RF feedback path beside noisy digital or switching nodes.
Design the 5.5 V supply and separate VP connection according to the official ADF4116 data sheet rather than assuming that both rails can be driven identically. The verified family description identifies a separate VP supply for extended tuning voltage in suitable systems. Confirm bypass-capacitor values, voltage tolerances, startup behavior, and the allowed relationship between the supply rails before layout release.
Do not select the prescaler, A counter, B counter, reference divider, and charge-pump current independently. Each value affects the synthesized frequency, lock range, loop dynamics, and phase noise. Build a frequency-plan spreadsheet and validate every programmed value against the official data-sheet limits. Also verify the target output frequency is below the applicable prescaler and device limits rather than relying only on the 550 MHz headline figure.
Treat the reference and RF feedback networks as controlled-impedance RF paths, and keep the loop-filter ground return short and symmetric. Poor soldering, long vias, unstable reference amplitude, or an incorrectly sized filter capacitor can dominate phase noise and lock behavior. Measure lock state and spectral performance in the final enclosure and with the intended reference source; the verified web results do not provide numerical phase-noise targets.
