ADF4113BRU Обзор
An integer-N PLL is a frequency-synthesizer category in which the feedback prescaler and integer counters establish the output frequency while the phase-frequency detector and charge-pump network close the loop around a voltage-controlled oscillator. The ADF4110 family therefore belongs to the broader hierarchy of clock and timing ICs, frequency synthesizers, phase-locked loops, RF signal-chain ICs, and semiconductors. Integer-N operation simplifies control compared with fractional-N architectures, while the maximum RF input rate enables high-frequency local-oscillator designs when the VCO and loop bandwidth are suitable.
The ADF4113BRU supports RF synthesis up to 4.0 GHz and includes programmable dual-modulus prescaling, programmable charge-pump currents, a separate charge-pump supply, and a programmable reference divider. The family documentation also identifies 3 V system operation. Separate charge-pump supply capability allows extended tuning-voltage headroom, which is useful when the external VCO requires a tuning range beyond the main supply rail. The programmable charge-pump current provides another control point for loop dynamics and reference-spur trade-offs.
The internal signal path uses a low-noise digital phase-frequency detector, precision charge pump, programmable reference divider, A and B counters, and P/P+1 dual-modulus prescaler. This arrangement is intended for integer-N local oscillators in RF upconversion and downconversion paths. The 16-TSSOP body is 4.40 mm wide and corresponds to the 0.173-inch package description listed by DigiKey. Package, lead finish, and orderable suffix must be checked against the Analog Devices ordering guide before substituting an alternative.
Typical uses include GSM and other wireless receiver or transmitter local oscillators, RF upconversion and downconversion blocks, communications test equipment, and frequency-generation subsystems. In such systems, the reference divider can reduce a high-frequency reference before comparison with the divided VCO output. The A counter, B counter, and dual-modulus prescaler determine the integer multiplication relationship, while the charge pump and external loop filter translate phase error into VCO tuning voltage.
The principal design constraint is loop stability. Component values for the charge-pump, loop filter, and VCO must be derived for the actual reference frequency, target output frequency, prescaler, phase margin, and tuning range. RF routing also requires short, controlled-impedance paths, solid return planes, and careful separation between sensitive synthesizer inputs and high-energy clock or switching nodes. The ADF4113 datasheet family should be consulted for the complete pin table and application circuit.
This product record combines verified manufacturer and distributor information with a focused comparison of same-package options, practical loop-filter and layout guidance, and commercial availability context. It is intended to help engineers confirm footprint, frequency capability, programming architecture, and source-document status before committing a PLL design to layout or production.

GSM Receiver Local Oscillator
ADF4113BRU fits a GSM receiver local-oscillator block because the ADF4110 family is intended for receiver and transmitter upconversion and downconversion paths. The manufacturer datasheet describes a 13 MHz TCXO feeding the reference input, an on-chip reference divider of 65 for 200 kHz channel spacing, and an external V controlled by the charge-pump loop filter. In operation, the phase-frequency detector compares the divided reference with the divided VCO feedback, while the A counter, B counter, and dual-modulus prescaler establish the integer relationship. The design must still verify VCO tuning range, divider capability at the selected channel, loop phase margin, and reference suppression at the intended cellular frequencies.
Рекомендуется
RF Upconversion and Downconversion
The ADF4113BRU can generate a programmable local-oscillator signal for RF upconversion or downconversion because it combines a 4.0 GHz-capable RF input path with programmable prescaling and integer counters. The loop compares the programmable reference divider against the P/P+1 prescaled VCO feedback, and the charge pump drives the external VCO tuning input through the loop filter. This architecture supports channelized radio architectures where a stable reference and programmable synthesis are required. Engineers should confirm that the prescaler supports the selected operating band, that the charge-pump voltage range covers the VCO requirement, and that the PCB preserves reference and feedback signal integrity.
Рекомендуется
Wireless Transmitter Local Oscillator
ADF4113BRU is applicable to wireless transmitter local oscillators when integer-N channel synthesis is sufficient. The precision charge pump and programmable charge-pump current allow the loop dynamics to be adapted to the VCO, reference divider, and desired prescaler, while the low-noise digital phase-frequency detector supports phase-error reduction. The separate charge-pump supply can extend tuning-voltage headroom when the required VCO tuning range exceeds the main supply. Real transmitter implementations must account for output-buffer isolation, harmonics, filtering, conducted and radiated emissions, and reference spur energy; those system requirements are not established by the device package alone.
Рекомендуется
Communications Test and Measurement
ADF4113BRU can serve as the programmable RF synthesis element in a communications test instrument when an integer-N local oscillator is adequate. Its 4.0 GHz capability, programmable reference divider, A and B counters, and dual-modulus prescaler allow a stable reference to be converted into a selected test tone or local-oscillator frequency. The external loop filter must be designed around the selected reference, prescaler, target frequency, phase margin, and VCO tuning range. Calibration can then map instrument frequency errors and power levels, but high-accuracy metrology may require a more suitable direct-digital-synthesis or precision-signal-chain architecture.
Рекомендуется
RF Frequency-Synthesizer Subsystem
ADF4113BRU provides the core integer-N frequency-synthesizer functions for an RF frequency-synthesizer subsystem: reference division, programmable counters, dual-modulus feedback division, phase-frequency detection, and charge-pump current sourced to an external VCO. Its 16-TSSOP package supports compact surface-mount layouts, but successful implementation depends on partitioning the sensitive analog phase detector and charge-pump paths from noisy digital programming and RF return currents. The subsystem should include stable reference generation, intentional reference and charge-pump decoupling, controlled VCO routing, and a characterized loop filter to preserve phase margin across temperature and process corners.
Рекомендуется
Instrumented RF Signal Generator
An instrumented RF signal generator can use ADF4113BRU when the requested output is best generated through a phase-locked VCO rather than direct digital synthesis. The programmable reference divider and integer counters set the synthesis ratio, while the external loop filter establishes bandwidth and damping around the selected VCO. This is particularly relevant where integer channel spacing is acceptable and a synthesizer-and-VCO combination offers suitable phase noise. The implementation should include output-level control, harmonic filtering, frequency calibration, and reference locking. Because the supplied data does not provide output-power, phase-noise, tuning-speed, or temperature specifications, those performance claims must be taken from the complete ADF4113 datasheet and system measurements.

Заметки по проектированию
Do not treat the 16-TSSOP outline as proof of drop-in compatibility. The verified search results establish the shared package class for the listed alternatives, but they do not expose complete pin maps, RF-input limits, counter widths, register maps, or ordering details for every candidate. Before replacing ADF4113BRU, compare the manufacturer pin tables, maximum input frequency, prescaler ranges, charge-pump specification, supply limits, and device-register behavior. In particular, the fractional-N architecture of ADF4153BRUZ changes the synthesis method even if the footprint matches.
Place the phase-frequency-detector, charge-pump, and loop-filter section directly adjacent to the relevant IC and VCO-control pins, with the shortest practical return path through a solid ground plane. Keep the reference input and RF feedback routes away from digital-programming traces and switching-node copper. Decouple the main supply and separate VP charge-pump supply independently at the device. The datasheet identifies a separate charge-pump supply for extended tuning voltage, so its voltage and return requirements must be followed exactly rather than assumed to follow the 3 V system rail.
Design the loop filter around the actual reference frequency, target RF output, prescaler, charge-pump setting, VCO gain, and required tuning range. The manufacturer family material provides example loop-filter component values for defined conditions, but those values are not universal. Recalculate the filter for each band and verify phase margin, lock range, reference-spur contribution, and startup behavior. Estimated calculations should be labeled as estimates and validated through simulation and bench measurements before release.
