Replacement verdict
Compatible functional replacement candidate
The ADF4360-1BCP and ADF4360-2BCPZ are both integrated integer-N PLL synthesizers with VCO from the same ADF4360 family, sharing a common 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 | ADF4360-2BCPZ | ADF4360-1BCP | Why it matters |
|---|---|---|---|
| Frequency Range (Min) | 1850 MHz | 2050 MHz | Defines the lowest output frequency the synthesizer can generate; a lower minimum allows operation in lower bands. |
| Frequency Range (Max) | 2170 MHz | 2450 MHz | Sets the highest output frequency; the upper bound determines suitability for higher-band applications. |
| Typical Output Frequency | 2000 MHz | 2300 MHz | The nominal center frequency indicates the primary intended operating band of each variant. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Both parts share the same supply range, so power supply design is interchangeable between them. |
| Package / Case | 24-LFCSP (4x4 mm) | 24-LFCSP (4x4 mm) | Identical package and footprint allow drop-in board replacement without layout changes. |
| Number of Pins | 24 | 24 | Matching pin count supports pin-compatible substitution on existing PCBs. |
| Interface Type | 3-wire serial (SPI) | 3-wire serial (SPI) | Same control interface means firmware and microcontroller connections remain compatible. |

Frequently asked questions
What are the key differences between the ADF4360-1BCP and ADF4360-2BCPZ?
The ADF4360-1BCP and ADF4360-2BCPZ are both integrated integer-N synthesizers with VCOs from Analog Devices, but they differ in frequency range and package. The ADF4360-1BCP covers 2050 MHz to 2450 MHz and is supplied in a 24-lead LFCSP (CP-24) package. The ADF4360-2BCPZ covers 1850 MHz to 2170 MHz and is supplied in a 24-lead LFCSP (CP-24-2) package with a Pb-free, RoHS-compliant finish. Both share the same functional architecture, including the 32-bit register interface and charge pump.
Are the ADF4360-1BCP and ADF4360-2BCPZ pin-compatible?
Both devices use a 24-lead LFCSP package with the same pin count and identical pin functions (CLK, DATA, LE, CP, VCO supply, RF outputs, etc.), so they are functionally pin-compatible. However, the ADF4360-2BCPZ is the Pb-free/RoHS-compliant version (suffix Z), while the ADF4360-1BCP is the non-RoHS version. PCB land patterns are the same, but the solder finish and compliance status differ.
What is the frequency range of each device?
The ADF4360-1BCP has an integrated VCO operating from 2050 MHz to 2450 MHz. The ADF4360-2BCPZ has an integrated VCO operating from 1850 MHz to 2170 MHz. Both devices include a divide-by-2 output option, allowing lower output frequencies when the fundamental VCO range is divided.
Can the ADF4360-2BCPZ directly replace the ADF4360-1BCP in an existing design?
Direct replacement is possible only if the target frequency falls within the ADF4360-2BCPZ range of 1850 MHz to 2170 MHz and the design accepts the Pb-free/RoHS package finish. Because the ADF4360-1BCP covers 2050 MHz to 2450 MHz, applications operating above 2170 MHz cannot use the ADF4360-2BCPZ. Register programming and loop filter design should be revalidated against the respective datasheets.
Do both devices use the same programming interface and register map?
Yes. Both the ADF4360-1BCP and ADF4360-2BCPZ use the same 3-wire serial interface (CLK, DATA, LE) and the same 32-bit register structure, including the R counter, N counter, and control registers. This allows firmware written for one device to be reused on the other, provided the frequency and charge pump settings are adjusted for the target VCO range.
What are the supply voltage and current requirements for these synthesizers?
Both devices operate from a nominal 3.0 V to 3.6 V supply. The ADF4360-1BCP and ADF4360-2BCPZ each integrate a VCO and PLL, and typical current consumption is in the range of approximately 30 mA to 50 mA depending on the programmed charge pump current and VCO settings. Designers should consult the respective datasheets for exact supply current versus frequency and configuration.
Which device should be selected for a 2.1 GHz application?
For a 2.1 GHz application, the ADF4360-2BCPZ (1850 MHz to 2170 MHz) covers the target frequency within its fundamental VCO range. The ADF4360-1BCP (2050 MHz to 2450 MHz) also covers 2.1 GHz, but the ADF4360-2BCPZ provides better centering within its range. Selection should also consider RoHS compliance requirements, since the ADF4360-2BCPZ is the Pb-free version.
Are evaluation boards and reference designs available for both parts?
Analog Devices provides evaluation boards for the ADF4360 family, and the same evaluation platform supports both the ADF4360-1BCP and ADF4360-2BCPZ, with the VCO frequency range being the primary difference. Reference loop filter designs and software are available in the respective product datasheets and evaluation board documentation.
