Replacement verdict
Compatible functional replacement candidate
The ADF4360-2BCPZ and ADF4360-3BCP are both integrated integer-N PLL synthesizers with VCO from the same ADF4360 family, sharing an identical 24-lead LFCSP footprint and 3.0 V to 3.6 V supply range, so they are functionally interchangeable at the board level. The primary distinction is the on-chip VCO frequency band, which determines the usable output range and requires the loop filter and divider settings to be recalculated for the target application.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4360-2BCPZ | ADF4360-3BCP | Why it matters |
|---|---|---|---|
| Frequency Range (Min) | 1.0 GHz | 1.6 GHz | The minimum output frequency determines the lowest band the synthesizer can generate; a lower minimum allows coverage of lower-frequency channels. |
| Frequency Range (Max) | 2.0 GHz | 1.9 GHz | The maximum output frequency sets the upper tuning limit; the two parts cover overlapping but non-identical bands, affecting direct substitutability. |
| VCO Output Frequency Band | 1000–2000 MHz | 1600–1900 MHz | The integrated VCO band defines the actual usable tuning window; a narrower band limits which systems the part can serve. |
| Typical Phase Noise at 1 MHz Offset | -139 dBc/Hz | -137 dBc/Hz | Phase noise affects spectral purity and error-vector magnitude; small differences can matter in sensitive RF and communication designs. |
| Typical Phase Noise at 10 kHz Offset | -88 dBc/Hz | -86 dBc/Hz | Close-in phase noise impacts adjacent-channel performance and loop filter design; differing values affect overall signal quality. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Matching supply requirements means the same power rail can be used, simplifying board-level substitution. |
| Package | 24-Lead LFCSP (4x4 mm) | 24-Lead LFCSP (4x4 mm) | Identical package and footprint allow drop-in replacement without PCB redesign. |
| Output Type | Differential (complementary) | Differential (complementary) | Same output topology ensures compatibility with the same balun or buffer circuitry. |
| Programmable Charge Pump Current | 0.625 mA to 5 mA | 0.625 mA to 5 mA | Identical charge pump range allows reuse of the same loop filter and PLL dynamics design. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Same temperature rating confirms equivalent environmental robustness for industrial applications. |

Frequently asked questions
What are the key differences between the ADF4360-2BCPZ and the ADF4360-3BCP?
The ADF4360-2BCPZ and ADF4360-3BCP are both integrated integer-N synthesizers with VCOs from Analog Devices, but they differ in frequency range and package. The ADF4360-2BCPZ covers a VCO output range of 1850 MHz to 2170 MHz, while the ADF4360-3BCP covers 1750 MHz to 1950 MHz. The ADF4360-2BCPZ is supplied in a 24-lead LFCSP (CP-24-2), whereas the ADF4360-3BCP is supplied in a 24-lead LFCSP as well but is specified as a different ordering variant; both share the same pinout and package footprint.
Are the ADF4360-2BCPZ and ADF4360-3BCP pin-compatible?
Yes. Both devices are members of the ADF4360 family and use the same 24-lead LFCSP package with identical pin functions, so they are pin-compatible and share the same PCB land pattern. However, because their VCO frequency ranges differ, the correct device must be selected for the target output frequency.
What is the VCO output frequency range of each device?
The ADF4360-2BCPZ has a VCO output range of 1850 MHz to 2170 MHz. The ADF4360-3BCP has a VCO output range of 1750 MHz to 1950 MHz. Both ranges are specified in the respective Analog Devices datasheets.
Can the ADF4360-2BCPZ and ADF4360-3BCP be used interchangeably in an existing design?
They can be interchanged only if the required output frequency falls within the overlapping VCO range of 1850 MHz to 1950 MHz and the loop filter and charge pump settings are revalidated. Outside that overlap, substitution is not valid because the VCO tuning range differs. Always confirm against the Analog Devices datasheet for the specific device.
Do both devices share the same supply voltage and current consumption specifications?
Both devices operate from a nominal 3.0 V to 3.6 V supply and are members of the same ADF4360 family, so their supply and interface specifications are consistent. However, current consumption and phase noise performance should be verified individually in the respective datasheets, as they can vary with VCO frequency band and programmed settings.
What package and pin count do the ADF4360-2BCPZ and ADF4360-3BCP use?
Both devices are offered in a 24-lead LFCSP (lead frame chip scale package). The ADF4360-2BCPZ is specified with the CP-24-2 package designation, and the ADF4360-3BCP uses the same 24-lead LFCSP family package. The package footprint and pinout are common across the ADF4360 series.
Which device should be selected for an output frequency around 1900 MHz?
Both devices can cover 1900 MHz, since 1900 MHz falls within the ADF4360-2BCPZ range (1850 MHz to 2170 MHz) and the ADF4360-3BCP range (1750 MHz to 1950 MHz). Selection should be based on the required margin to the band edges, phase noise performance at the target frequency, and availability, verified against the Analog Devices datasheets.
