ADF4007BCP - 7.5GHz Divider/PLL Synthesizer | Analog Devices
Teilenummer: ADF4007BCP ✓ AktivADF4007BCP Übersicht
A phase-locked loop, or PLL, is a feedback-controlled frequency-synthesis circuit in which a phase-frequency detector compares a reference signal with a divided feedback signal. A charge pump and external loop filter then convert phase error into a tuning voltage for a voltage-controlled oscillator. The ADF4007BCP integrates the phase detector, precision charge pump, programmable divider, and prescaler used to construct such a loop.
The ADF4007BCP supports RF operation to 7.5 GHz and phase-frequency-detector operation to 120 MHz. Its reference divider is permanently set to 2, permitting an external REFIN frequency up to 240 MHz. Divide ratios are selected through two external control pins, while RSET controls charge-pump current. A separate VP supply allows the tuning-voltage range to exceed what the main 3.3 V supply alone would permit.
The device also includes hardware power-down control for system-state management. According to the Analog Devices ADF4007 data sheet, the loop-filter values derived with ADIsimPLL provide typical phase noise of -100 dBc/Hz at a 10 kHz carrier offset, while the loop filter attenuates spurs below -90 dBc. These figures make the synthesizer suitable for RF communication systems requiring predictable phase noise and spur performance.
Typical uses include wireless transceiver frequency synthesis, microwave and RF test equipment, and communications infrastructure. In a PLL implementation, the ADF4007BCP compares the divided feedback output with REFIN and drives a VCO tuning input through an external charge-pump loop filter. Designers must select divider ratios, loop bandwidth, and passive values that satisfy the required phase-noise and spur limits.
A key implementation consideration is the exposed thermal pad. The data sheet controls its connection to ground and provides thermal and electrical layout guidance. Input, reference, charge-pump, and loop-filter connections should follow the manufacturer’s recommended layout to avoid introducing additional phase noise or instability.
This page consolidates the verified manufacturer information, available ordering data, same-package cross-references, comparison points, and practical design guidance for engineers evaluating the ADF4007BCP.

Typische Anwendungen
ADF4007BCP ist geeignet für 6 Anwendungs: Wireless Transceiver Frequency Synthesis, Microwave RF Signal Generation, Communications Infrastructure RF Synthesis, RF and Microwave Test Equipment, High-Frequency Local Oscillator, Frequency-Changing RF Up/Down Converters.
Wireless Transceiver Frequency Synthesis
The ADF4007BCP fits wireless transceiver local-oscillator synthesis because it supports RF frequencies up to 7.5 GHz and PFD operation up to 120 MHz. It can divide a divided feedback signal, compare it with REFIN, and use its precision charge pump to drive an external VCO tuning input. A separate VP supply expands the available tuning-voltage range, while RSET permits charge-pump-current adjustment for loop dynamics. The implementation trade-off is that engineers must design and validate an external loop filter against phase-noise and spur targets.
Empfohlen
Microwave RF Signal Generation
The ADF4007BCP is applicable to microwave signal-generation systems requiring a high-frequency divider and PLL core rather than a fully integrated oscillator. Its 7.5 GHz RF operating limit gives the feedback divider substantial headroom for microwave carrier generation. The phase detector can operate to 120 MHz, and the permanently fixed divide-by-2 reference path accepts REFIN up to 240 MHz. Performance depends on the selected divide ratio, external VCO tuning range, and carefully calculated loop-filter component values.
Empfohlen
Communications Infrastructure RF Synthesis
The ADF4007BCP can serve as the frequency-synthesizing core in communications infrastructure that derives coherent RF references from a stable external oscillator. Its 120 MHz maximum PFD rate permits useful comparison bandwidth for suitable reference plans, while the 7.5 GHz RF rating supports high-frequency channels. The separate VP supply is valuable when a VCO requires a tuning range broader than the 3.3 V main rail. Deployment requires local loop-filter analysis, reference-jitter budgeting, and validation of spur behavior in the completed receiver or transmitter.
Empfohlen
RF and Microwave Test Equipment
The ADF4007BCP offers a practical way to construct a tunable RF source for test equipment when the system already includes an external VCO. The 7.5 GHz divider capability and 120 MHz PFD limit support carrier generation across high-frequency test ranges. According to the Analog Devices data sheet, a typical ADIsimPLL-derived loop-filter implementation reaches approximately -100 dBc/Hz at a 10 kHz offset and attenuates spurs below -90 dBc. These are typical—not guaranteed maximum—figures and must be confirmed for the selected VCO and loop bandwidth.
Empfohlen
High-Frequency Local Oscillator
The ADF4007BCP can form the synthesizer section of a high-frequency local oscillator using an external voltage-controlled oscillator and loop filter. Its RF bandwidth extends to 7.5 GHz, while the independent charge-pump supply helps accommodate the oscillator’s tuning-voltage requirements. The reference divider is fixed at 2, so the architecture is particularly relevant when a reference plan intentionally avoids an adjustable reference divider. Designers should still verify phase margin, reference-noise multiplication, and capture behavior across all required divide ratios.
Empfohlen
Frequency-Changing RF Up/Down Converters
The ADF4007BCP is suitable for the programmable frequency-generation section of RF up-converters and down-converters. The phase detector compares a divided RF output with the reference, and the charge pump generates the tuning correction applied to the local oscillator. Operation to 7.5 GHz accommodates many microwave conversion bands, while the 120 MHz PFD ceiling supports reference architectures with a relatively high comparison rate. Image rejection and conversion performance still depend on the complete synthesizer, filters, mixer architecture, and selected loop bandwidth.

Designhinweise
Use the Analog Devices recommended land pattern and route the charge-pump and loop-filter connections as short as practical. Keep the external VCO tuning path away from noisy digital and switching nodes, and provide a clean return path for the reference and RF divider connections. Because the verified data does not provide exact layout dimensions, the package drawing and ADF4007 data sheet should be treated as the authoritative layout sources.
Connect and thermally couple the exposed pad according to the manufacturer package guidance. The verified material identifies the ADF4007BCP as a 20-lead LFCSP with an exposed pad but does not provide verified junction-temperature or thermal-resistance figures. Before production release, obtain those values from the data sheet and calculate worst-case dissipation using the actual supply voltage, VCO tuning voltage, and charge-pump duty cycle.
Determine the loop bandwidth from phase-noise, spur, reference-jitter, and lock-time requirements rather than copying one filter value across all divide ratios. The Analog Devices data sheet notes that ADIsimPLL was used to derive the shown component values, with typical phase noise of -100 dBc/Hz at 10 kHz offset and spurs below -90 dBc. Validate these typical figures using the actual VCO, reference source, crystal or oscillator, and system thermal conditions.
Do not treat the 7.5 GHz RF rating as permission to exceed the 120 MHz PFD limit or the 240 MHz external REFIN limit. The reference divider is permanently set to 2, so reference planning cannot compensate with an adjustable reference divider. Also avoid omitting the separate charge-pump supply or RSET path; these functions are central to the advertised tuning-voltage range and charge-pump-current control.
