ADF5356BCPZ - 13.6 GHz Wideband PLL Synthesizer | Analog Devices
Référence : ADF5356BCPZ ✓ ActifADF5356BCPZ Présentation
A microwave wideband synthesizer is a clock-and-timing IC that combines a voltage-controlled oscillator with a phase-locked loop to produce a stable, programmable output frequency. The broader hierarchy is frequency synthesizer > PLL frequency synthesizer > clock generation and timing IC > integrated circuit. This architecture is useful when a system needs precise RF frequency generation from a stable reference without implementing every oscillator and feedback function as discrete circuitry.
The ADF5356 supports integer-N and fractional-N synthesis, giving designers flexibility in channel spacing, reference-to-output ratios, and phase-noise planning. Its output stage includes divide ratios of 1, 2, 4, 8, 16, 32, and 64, extending usable output coverage below the VCO fundamental range. According to the Analog Devices product page, the wideband microwave VCO supports frequency operation across the stated 3400 MHz to 6800 MHz fundamental range.
The integrated microwave VCO is the central architecture of the device. A PLL locks the VCO to an external reference, while an external passive loop filter shapes loop dynamics and phase noise. Fractional-N operation permits division ratios that are not integers, although final settling time, spurious performance, and loop-filter design depend on the complete system configuration. The exact supply voltages, reference-frequency limits, register map, phase-noise values, and temperature limits are not included in the supplied web results.
Typical uses include microwave and RF signal sources, communications test equipment, local oscillators, frequency-conversion subsystems, and instrumentation requiring programmable RF outputs. The divider chain makes the device relevant when a system needs output below the 3400 MHz to 6800 MHz VCO range. The evaluation hardware identified in the verified data includes a differential 122.88 MHz reference TCXO, a loop filter, USB interface, power connections, and SMA connectors.
For PCB implementation, follow the exposed-pad land pattern and thermal-via recommendations in the manufacturer datasheet. The external loop filter, reference components, RF output matching network, supply decoupling, and exposed-pad thermal design materially affect phase noise, lock behavior, output power, and system stability. Verify all voltage, temperature, and absolute-maximum limits before releasing a production design.
This product record consolidates the verified manufacturer function, frequency-range, divider, mute-function, package, evaluation-board, distributor, and replacement information into one engineering reference. It also distinguishes documented drop-in candidates from broader functional alternatives and flags unavailable electrical data explicitly rather than estimating it.

Applications typiques
ADF5356BCPZ convient pour 6 applications: Microwave RF Signal Source, Communications Test Equipment, RF Frequency Conversion Subsystem, Microwave Signal Generator, Industrial RF Measurement System, Laboratory RF Calibration Setup.
Microwave RF Signal Source
The ADF5356BCPZ fits a programmable microwave RF signal source because its integrated VCO spans 3400 MHz to 6800 MHz and the device supports both fractional-N and integer-N PLL operation. A stable external reference and a carefully selected external loop filter establish the synthesis relationship between reference frequency and requested RF output. This allows one synthesizer to cover multiple microwave test frequencies without relying on a bank of switched oscillators. The divide chain can also produce outputs as low as 53.125 MHz when the selected divider is 64. System designers must still verify phase noise, output power, reference spur behavior, settling time, and loop stability against the complete datasheet limits; those values were not included in the supplied search excerpts.
Recommandé
Communications Test Equipment
The ADF5356BCPZ is appropriate for programmable communications test equipment that must synthesize microwave and RF frequencies from a shared reference. Its 3400 MHz to 6800 MHz fundamental VCO range and divide-by-1 through divide-by-64 outputs provide broad frequency coverage, while fractional-N mode offers additional channel-planning flexibility. The part can therefore serve as the local oscillator in a receiver or transmitter model. The external loop filter remains critical because it influences lock behavior and phase-noise performance. Before using the device in production instrumentation, engineers should confirm output-power variation, spur levels, lock time, supply requirements, and temperature behavior using the official datasheet and Analog Devices evaluation hardware.
Recommandé
RF Frequency Conversion Subsystem
The ADF5356BCPZ can serve as the synthesizer in an RF frequency-conversion subsystem requiring a programmable local oscillator. Its maximum stated frequency is 13.6 GHz, while the integrated VCO itself operates from 3400 MHz to 6800 MHz, allowing the divider network to address lower RF outputs down to 53.125 MHz. Integer-N and fractional-N operation provide choices for reference ratios and channel spacing. In a converter, phase noise and reference spurs can influence the translated signal, so the external loop filter and reference source should be optimized together with the RF output network. Exact tuning range, output power, and spur specifications require verification because those numerical values were not present in the supplied verified excerpts.
Recommandé
Microwave Signal Generator
The ADF5356BCPZ is well suited to a compact microwave signal generator in which one programmable synthesizer must replace multiple fixed-frequency sources. Its 3400 MHz to 6800 MHz fundamental range covers common microwave bands, while seven divider choices allow lower RF outputs without changing the VCO architecture. Both integer-N and fractional-N modes support different planning approaches depending on reference availability and required channel spacing. The verified evaluation board also demonstrates how the device can be paired with a 122.88 MHz differential reference TCXO, an external loop filter, USB control, and SMA connectors. Production designers should still validate spectral purity, settling behavior, output level, and frequency accuracy over the intended environmental range.
Recommandé
Industrial RF Measurement System
The ADF5356BCPZ can support an industrial RF measurement system that requires repeatable programmable frequencies across a wide tuning range. The integrated VCO reduces the number of separate frequency-generation blocks, and the divider chain reaches down to 53.125 MHz for lower-frequency test points. Fractional-N operation is useful when the system cannot provide every desired output ratio directly from the reference, while integer-N operation may simplify initial control and loop analysis. Because this is a precision PLL device, PCB layout, reference phase noise, loop-filter component tolerances, supply decoupling, and exposed-pad thermal management all affect useful performance. The EVAL-ADF5356 provides a practical starting point for evaluating those interactions before custom hardware is released.
Recommandé
Laboratory RF Calibration Setup
The ADF5356BCPZ is suitable for a laboratory RF calibration setup where multiple frequencies must be generated with a common reference and controlled through a digital interface. Its 3400 MHz to 6800 MHz fundamental VCO range and divider options create broad output flexibility, while fractional-N and integer-N modes allow the control architecture to be adapted to the reference frequency. The documented evaluation-board arrangement includes a 122.88 MHz differential reference TCXO, loop filter, USB interface, power connections, and SMA connectors, providing a practical basis for laboratory integration. Before treating the evaluation arrangement as a production reference design, verify regulator noise, connector loss, calibration method, output-power calibration, temperature drift, and spectral performance. Exact calibration and phase-noise numbers are not available in the supplied verified data.

Principaux différenciateurs

- Same-family electrical configuration (vs ADF5356ACPZ)
- Single-chip PLL and VCO integration (vs ADF5355BCPZ)
Notes de conception
Use the exact Analog Devices recommended land pattern for the 32-lead WFQFN exposed-pad CSP and verify the exposed-pad thermal-via arrangement against the current manufacturer datasheet. Keep the RF output path, reference input, and sensitive loop-filter components away from noisy digital and switching-supply nodes. Because the supplied excerpts do not provide the complete pin table or recommended PCB layout, no pin numbers beyond the specifically documented Pin 22 RSET connection should be assumed.
The ADF5356BCPZ requires an external reference and external loop filter, so its power-supply design must account for both the internal PLL-VCO and surrounding RF circuitry. The supplied data does not identify the required supply voltages or current, so engineers must obtain those values from the manufacturer datasheet rather than selecting regulators from unverified ratings. Use local high-frequency decoupling and confirm ground return paths under the final RF-output load before evaluating phase noise or lock performance.
Do not treat the ADF5356 upgrade from an ADF5355 as a firmware-only substitution. Analog Devices AN-1460 states that Register 13 is added and specifically discusses the resistor connected to Pin 22. Confirm the register sequence, initial configuration, reference frequency, divider path, and RSET arrangement. The same caution applies when substituting another ADF5356 package or temperature-grade variant, because the verified excerpts do not establish every electrical or lifecycle difference.
Evaluate the reference input, loop filter, and RF output network as one signal-integrity system. Reference phase noise and loop-filter design influence the synthesizer's output noise, while reference spurs can appear at predictable offsets from the carrier. The documented EVAL-ADF5356 uses a differential 122.88 MHz reference TCXO, an external loop filter, and SMA connectors; it is a useful baseline for comparing a custom layout and component set under controlled conditions.
Informations de conformité
The supplied verified excerpts do not state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. The component is a clock-and-timing integrated circuit, so AEC-Q100 qualification is not indicated by the available data.
