Replacement verdict
Compatible functional replacement candidate
The ADF4360-1BCPZ and ADF4360-2BCP 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 frequency plan. Designers should confirm that the required output frequency falls within the selected variant's VCO range before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4360-1BCPZ | ADF4360-2BCP | Why it matters |
|---|---|---|---|
| Frequency Range (Min) | 1050 MHz | 1850 MHz | Defines the lowest output frequency the synthesizer can generate; a lower minimum allows operation in lower bands. |
| Frequency Range (Max) | 2400 MHz | 2170 MHz | Sets the highest achievable output frequency; determines suitability for higher-band applications. |
| VCO Frequency Range | 1050 MHz to 2400 MHz | 1850 MHz to 2170 MHz | The integrated VCO tuning range directly constrains which output frequencies can be locked without external components. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Both parts share the same supply requirement, so power-rail design is interchangeable. |
| Package / Pin Count | 24-Lead LFCSP | 24-Lead LFCSP | Identical footprint and pinout enable drop-in board replacement without layout changes. |
| Output Type | Differential (complementary) outputs | Differential (complementary) outputs | Matching output topology ensures the same external matching and buffer circuitry can be reused. |
| Programmable Divider / Interface | SPI-compatible 3-wire interface | SPI-compatible 3-wire interface | Same digital control interface means firmware and microcontroller connections remain compatible. |
| Typical Application Band | ~1.0 GHz to 2.4 GHz (e.g., WLAN, ISM) | ~1.85 GHz to 2.17 GHz (e.g., PCS, DCS) | The intended operating bands differ, so substitution depends on whether the target frequency falls within the narrower ADF4360-2 range. |

Frequently asked questions
What are the key differences between the ADF4360-1BCPZ and the ADF4360-2BCP?
Both are integrated integer-N synthesizers with VCOs from Analog Devices, but they differ in frequency range and package. The ADF4360-1BCPZ covers 2050 MHz to 2450 MHz and is supplied in a 24-lead LFCSP (CP-24-2). The ADF4360-2BCP covers 1850 MHz to 2170 MHz and is supplied in a 24-lead LFCSP (CP-24). The ADF4360-1BCPZ is the RoHS-compliant version of the ADF4360-1, while the ADF4360-2BCP is the non-RoHS lead-frame variant of the ADF4360-2.
Can the ADF4360-1BCPZ and ADF4360-2BCP be used interchangeably in the same design?
Not directly. Although both share the same 24-lead LFCSP footprint and register map, their VCO frequency ranges differ: 2050–2450 MHz for the ADF4360-1BCPZ versus 1850–2170 MHz for the ADF4360-2BCP. A design tuned for one frequency band will not cover the other without revalidating the loop filter, VCO tuning range, and output matching network against the respective datasheet.
What is the difference in RoHS compliance between the ADF4360-1BCPZ and the ADF4360-2BCP?
The ADF4360-1BCPZ is the RoHS-compliant ordering code, indicated by the "Z" suffix in the part number. The ADF4360-2BCP does not carry the "Z" suffix and is the non-RoHS version. Designs requiring RoHS compliance should use the "Z"-suffixed variant of the corresponding frequency option.
Do the ADF4360-1BCPZ and ADF4360-2BCP share the same package and pinout?
Both devices are offered in a 24-lead LFCSP package with the same pin functions and register interface, so the PCB land pattern is compatible. However, the exact package code differs (CP-24-2 for the ADF4360-1BCPZ versus CP-24 for the ADF4360-2BCP), and the designer should confirm the package drawing in the respective datasheet before layout.
What supply voltage and current consumption do the ADF4360-1BCPZ and ADF4360-2BCP require?
Both devices operate from a 3.0 V to 3.6 V supply. Typical current consumption is approximately 45 mA for the ADF4360-1BCPZ and approximately 45 mA for the ADF4360-2BCP, with a power-down mode that reduces current to a few microamperes. Exact values should be taken from the respective Analog Devices datasheets.
What is the phase noise performance of the ADF4360-1BCPZ and ADF4360-2BCP?
Both parts specify a normalized phase noise floor of approximately -219 dBc/Hz in the datasheet, with typical in-band phase noise around -88 dBc/Hz at a 1 kHz offset for a 200 kHz PFD frequency. Actual phase noise depends on the selected VCO band, loop filter, and reference, so the designer should consult the phase noise plots in the respective datasheet.
What is the difference in output frequency range between the ADF4360-1BCPZ and the ADF4360-2BCP?
The ADF4360-1BCPZ VCO operates from 2050 MHz to 2450 MHz, while the ADF4360-2BCP VCO operates from 1850 MHz to 2170 MHz. Both provide a divided output and a complementary output, and the choice between them should be based on the target RF band of the application.
Are the ADF4360-1BCPZ and ADF4360-2BCP programmable through the same serial interface?
Yes. Both devices use the same 3-wire serial interface (CLK, DATA, LE) and the same 24-bit register map, so firmware written for one can generally be reused for the other. The register settings for the VCO band and charge pump current should still be adjusted to match the frequency range of the selected part.
