ADF4001BRU - 200 MHz Clock Generator PLL | Analog Devices
部品番号: ADF4001BRU ✓ 生産中ADF4001BRU 概要
A clock generator PLL is a frequency-control IC that compares a reference signal with a divided feedback signal and drives a tunable oscillator toward phase and frequency lock. Within the broader semiconductor hierarchy, the ADF4001 belongs to the clock and timing IC family and functions as a programmable frequency synthesizer for systems requiring a stable, low-noise reference clock. Its internal blocks include a low-noise digital phase-frequency detector, precision charge pump, programmable reference divider, 13-bit N counter, and 14-bit R counter.
Key features include 200 MHz bandwidth, programmable charge-pump currents, hardware and software power-down modes, and analog and digital lock detection. The separate charge-pump supply, designated Vp in the manufacturer data, supports extended tuning voltage in systems operating from 5 V. Hardware compatibility with the ADF4110, ADF4111, ADF4112, and ADF4113 families helps simplify software migration across related Analog Devices PLL designs.
The architecture allows the reference frequency to be divided through the R counter and the feedback frequency through the N counter. The phase-frequency detector and charge pump translate phase and frequency errors into a tuning correction for the controlled oscillator. Serial programming provides access to the counters and charge-pump settings, while the analog and digital lock indicators allow a host controller to monitor synchronization status.
Typical uses include low-noise clock sources for RF and microwave PLL systems, frequency synthesis in communications equipment, clock generation for instrumentation, and reference-clock distribution where programmable division is useful. The 16-lead TSSOP package is suitable for conventional surface-mount assembly, while the 2.7 V to 5.5 V supply range accommodates both lower-voltage and 5 V designs.
Designers should treat the charge-pump, loop-filter, and reference-divider settings as a coordinated system. The separate Vp connection must be decoupled according to the manufacturer's guidance, and the serial interface must preserve the required timing while counters and lock functions are programmed. Because the provided source data does not provide a complete pin map, engineers should verify every connection against the official ADF4001 data sheet before layout release.
This product summary consolidates the verified manufacturer specifications, current manufacturer pricing, package information, and engineering guidance for the ADF4001BRU. It also distinguishes verified device data from unavailable details, helping procurement and design teams avoid assumptions about pinout, operating temperature, compliance, or alternative-part compatibility.

主な用途
ADF4001BRU の用途: 6 件s: RF and Microwave PLL Clock Synthesis, Communications Equipment Frequency Synthesis, Low-Noise Instrumentation Clock Source, Precision Frequency Divider and Multiplier, Clock Distribution for Signal-Control Systems, Portable and Low-Power Clock Modules.
RF and Microwave PLL Clock Synthesis
The ADF4001BRU fits an RF or microwave PLL clock-generation stage because it combines 200 MHz bandwidth, a low-noise digital phase-frequency detector, a precision charge pump, and programmable divider counters. The 13-bit N counter and 14-bit R counter allow the reference and feedback paths to be divided for the required multiplication ratio. Its separate Vp charge-pump supply can provide extended tuning voltage in 5 V systems, while analog and digital lock detection helps a controller confirm synchronization. Design evaluation should include the actual reference source, loop filter, controlled oscillator, and required phase-noise profile because these external choices determine realized system performance.
おすすめ
Communications Equipment Frequency Synthesis
The ADF4001BRU can provide the programmable reference clock required by communications equipment with variable division and multiplication requirements. Its 3-wire serial interface allows a host processor to configure the N counter, R counter, and charge-pump current, while the 4.5 mA typical operating current supports low-power system architectures. The 2.7 V to 5.5 V operating range permits integration into both lower-voltage and 5 V designs. For transmitter or receiver subsystems, engineers should verify phase noise, lock time, reference purity, and tuning range together rather than treating the 200 MHz bandwidth as the sole performance criterion.
おすすめ
Low-Noise Instrumentation Clock Source
The ADF4001BRU is suitable for instrumentation that needs a programmable, lock-monitored clock rather than a fixed oscillator. The precision charge pump, programmable charge-pump current, and selectable reference and feedback division support loop optimization for different operating frequencies. Analog and digital lock detection can be used by test equipment or a control processor to prevent downstream measurements from starting before the synthesized clock is valid. The 16-lead TSSOP package supports conventional surface-mount assembly, and the 4.5 mA typical operating current is useful where power budget is constrained. Final phase-noise and lock-time results require loop-filter and reference-oscillator characterization.
おすすめ
Precision Frequency Divider and Multiplier
The ADF4001BRU can synthesize a programmed output from a stable reference by using its 14-bit R counter and 13-bit N counter within a phase-locked loop. This makes it relevant to clock-generation blocks that require selectable ratios while maintaining phase coherence with an upstream reference. The 3-wire serial interface supports electronic reconfiguration, allowing a system to select different output conditions without replacing the oscillator hardware. Because lock accuracy depends on divider ratios, loop gain, charge-pump settings, and filter characteristics, engineers should validate integer-ratio operation and settling behavior across every required frequency plan.
おすすめ
Clock Distribution for Signal-Control Systems
The ADF4001BRU can act as the coherent clock generator upstream of a distribution network in signal-control or conversion systems. Its programmable reference and feedback counters support multiple clock ratios, and the lock indicators allow supervisory logic to monitor synchronization. The low typical operating current of 4.5 mA is advantageous when the synthesizer is not the principal load, while hardware and software power-down modes provide additional control during inactive periods. The implementation should keep the reference path clean, provide appropriate charge-pump-loop filtering, and verify that downstream circuitry can tolerate the specified lock and re-lock behavior.
おすすめ
Portable and Low-Power Clock Modules
The ADF4001BRU fits compact, power-conscious clock modules because its stated operating range is 2.7 V to 5.5 V and its typical operating current is 4.5 mA. The 16-lead TSSOP package supports space-efficient surface-mount assembly, while programmable counters allow one device to serve several system clock plans. Hardware and software power-down modes can reduce activity when a synthesized output is not needed, and lock detection provides a usable status signal for power-management sequencing. Designers should still include adequate bypass and loop-filter components, validate startup behavior in the complete module, and confirm the exact environmental and compliance requirements from the complete manufacturer documentation.

設計ノート
Keep the reference input, phase-frequency detector, charge-pump output, and loop-filter components positioned close to the relevant ADF4001BRU pins. Route the feedback divider and reference-divider paths away from noisy digital return currents. The verified excerpts establish the 16-lead TSSOP package but do not provide a complete pin map, so the official Analog Devices schematic and layout guidance must be consulted before assigning traces or grounding.
Treat the main power supply and the separate Vp charge-pump supply as distinct paths. The manufacturer data sheet identifies Vp as a separate supply that allows extended tuning voltage in 5 V systems. Place the required bypass capacitors close to their associated pins, maintain a low-impedance ground return for the charge pump, and follow the manufacturer limits for supply sequencing and power-down. The available source does not provide capacitor values, so no numerical values are inferred here.
Do not assume that the 200 MHz bandwidth rating alone determines usable loop bandwidth or phase noise. Charge-pump current, N- and R-divider ratios, reference purity, loop-filter values, controlled-oscillator phase noise, and PCB layout all affect the result. Characterize lock time and phase noise over the required frequency range and verify digital and analog lock detection behavior in the final control firmware.
Use a clean, low-jitter reference source because the phase-frequency detector compares the reference path with the divided feedback path. Keep the reference trace short, provide return-path continuity, and avoid routing it beside high-current switching nodes. If the reference divider is not used at unity, validate the divider's contribution to phase noise and ensure the serial-interface activity does not disturb sensitive reference or charge-pump nodes.
