ADF4110BRU 概述
An RF PLL is a frequency synthesizer that locks a voltage-controlled oscillator to a stable reference frequency. It belongs to the clock and timing hierarchy: RF frequency synthesizer, PLL frequency synthesizer, clock and timing IC, and semiconductor. The ADF4110 family is intended for wireless receiver and transmitter local oscillators, where a programmable divider, phase-frequency detector, charge pump, A counter, and B counter establish the required output frequency.
The key verified features include a 5.5 V power supply, a separate charge-pump supply that allows an extended tuning-voltage range, programmable dual-modulus prescaler, programmable charge-pump currents, and support for 3 V systems. The 550 MHz upper PLL frequency is relevant to RF communications designs, while the 16-TSSOP package supports compact surface-mount implementation. Analog Devices markets the ADF4110 as a production part.
The architecture allows the reference input to be divided and compared with the divided feedback signal. The phase-frequency detector and charge pump then drive the tuning interface of a voltage-controlled oscillator. Exact counter widths, divider values, reference-frequency limits, output characteristics, pin names, and electrical limits should be confirmed in the manufacturer datasheet before layout or firmware release.
Typical uses include wireless receiver and transmitter local oscillators, RF upconversion and downconversion chains, and other frequency-generation systems requiring programmable RF channel selection. The device is most useful when the system already provides a stable reference and a suitable external VCO or oscillator arrangement.
Designers should preserve the required loop-filter components, keep RF and reference routing short, and verify phase-noise and lock-time behavior with the actual VCO and reference source. The PLL is not a standalone fixed-frequency oscillator; its external loop and reference design determine much of the final performance.

典型应用
ADF4110BRU 适用于 6 应用s: Wireless Receiver Local Oscillator, Wireless Transmitter Local Oscillator, RF Upconversion and Downconversion, Programmable RF Channel Selection, RF Test and Measurement Source, Compact Surface-Mount RF Module.
Wireless Receiver Local Oscillator
The ADF4110BRU fits a wireless receiver local-oscillator position because it is a programmable RF PLL frequency synthesizer with a verified maximum PLL frequency of 550 MHz. It can divide a stable reference through programmable counter paths and compare the result with divided RF feedback to produce a tuning correction for a VCO. This topology is useful for channel selection in receiver upconversion and downconversion chains. The design must still validate tuning range, lock behavior, phase noise, and spur performance against the actual VCO and loop filter.
推荐
Wireless Transmitter Local Oscillator
ADF4110BRU can provide programmable frequency generation for a wireless transmitter local oscillator, where a synthesized RF reference is needed for modulation or conversion stages. Its verified 550 MHz PLL capability, programmable dual-modulus prescaler, and programmable charge-pump current support closed-loop frequency control when paired with an external VCO. The external reference and loop filter determine phase noise and lock performance, so the transmitter requirement should specify reference purity, tuning voltage, settling time, and output power before component selection.
推荐
RF Upconversion and Downconversion
The ADF4110BRU is applicable to RF upconversion and downconversion systems that require a programmable local oscillator. Its low-noise digital phase-frequency detector, precision charge pump, programmable reference divider, programmable A and B counters, and dual-modulus prescaler form the control functions needed for an integer-N PLL. In a practical receiver or transmitter, the synthesized signal can drive a mixer or VCO chain while the loop suppresses frequency error. The final IF and RF frequency plan must be checked against the complete datasheet limits.
推荐
Programmable RF Channel Selection
ADF4110BRU supports programmable RF channel selection through its programmable counter architecture and dual-modulus prescaler. The digital programming interface can configure the desired frequency relationship between a stable reference and the RF feedback path, allowing multiple channels to be generated without changing the physical RF oscillator arrangement when the frequency plan remains within the device’s verified range. Firmware and hardware must preserve the required lock sequence and reference setup. Verify counter ranges, prescaler choices, and tuning-voltage limits in the manufacturer documentation.
推荐
RF Test and Measurement Source
ADF4110BRU can be used in a controlled RF test source when an external VCO or oscillator is included. The part provides the programmable PLL control functions needed to lock an RF reference to a stable reference, while the external loop filter and VCO determine phase noise and tuning accuracy. This arrangement can support laboratory channel simulations, RF stimulus generation, and repeatable frequency sweeps. Because the supplied data does not provide complete phase-noise or settling-time values, those specifications should be measured in the final loop rather than assumed from the IC name.
推荐
Compact Surface-Mount RF Module
The 16-pin TSSOP package makes ADF4110BRU suitable for compact surface-mount RF modules where programmable frequency generation is required alongside a reference source, VCO, loop filter, and RF matching network. The package reduces board area compared with larger through-hole or high-pin-count solutions, but high-frequency layout remains critical. Keep the reference and charge-pump paths compact, provide stable supply decoupling, and follow the datasheet land pattern. The supplied verified data identifies the package as 16-pin TSSOP with a 4.40 mm width.

设计说明
The ADF4110 family information identifies a 5.5 V power-supply arrangement and a separate VP charge-pump supply. Confirm the exact recommended analog, digital, and VP ranges in the manufacturer datasheet before designing the regulator network. Decouple each supply independently and route the return current away from the phase-frequency detector and charge-pump paths. The correct supply sequencing is especially important because the synthesizer depends on a stable reference and controlled tuning voltage during startup.
Use the datasheet land pattern for the 16-pin TSSOP package and place the reference-input, charge-pump, and feedback connections according to the manufacturer’s recommended layout. Keep the reference path short and controlled, and keep the charge-pump output and loop-filter components close to the IC. The supplied data confirms the package family and width but does not provide exact pin numbers, so the final PCB layout must be checked against the package pinout rather than inferred.
Treat the reference, prescaler, feedback, and loop-filter paths as RF-sensitive signal paths. Use a stable, low-noise reference source, preserve the intended impedance environment, and minimize parasitic capacitance on high-speed control lines. PLL phase noise and spur performance depend on the VCO, reference divider, loop bandwidth, charge-pump settings, and PCB parasitics, not only on the ADF4110BRU itself. Measure lock range and spectral performance in the assembled design.
Do not select ADF4110BRU from the maximum-frequency number alone. Confirm reference-input limits, prescaler options, counter ranges, VP tuning range, supply limits, temperature range, and package pinout in the exact datasheet. Also do not treat ADF4107BRU as a drop-in substitute solely because a comparison page exists; a valid replacement must preserve the electrical, programming, and mechanical behavior. Verify all details before releasing firmware or a production BOM.
合规信息
The supplied verified snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status for ADF4110BRU. Compliance must be confirmed using the exact Analog Devices ordering code and current manufacturer documentation.
