Replacement verdict
Compatible functional replacement candidate
The ADF4360-1BCPRL is a functionally compatible replacement candidate for the ADF4360-2BCPZ, sharing the same integrated PLL and VCO architecture, 24-lead LFCSP package, and 3.0 V to 3.6 V supply range, while differing primarily in frequency band coverage and output frequency range. Designers should validate the target frequency plan and loop filter against the specific band of operation before substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADF4360-2BCPZ | ADF4360-1BCPRL | Why it matters |
|---|---|---|---|
| Frequency Range (Min) | 1850 MHz | 2050 MHz | The lower bound of the output frequency range determines the lowest channel the synthesizer can generate; a part cannot tune below its minimum. |
| Frequency Range (Max) | 2170 MHz | 2450 MHz | The upper bound defines the highest channel achievable; substituting a part with a lower maximum would prevent operation at higher frequencies. |
| VCO Frequency Range | 1850 MHz to 2170 MHz | 2050 MHz to 2450 MHz | The integrated VCO must cover the target band; mismatched VCO range means the PLL cannot lock at the desired output frequency. |
| Supply Voltage | 3.0 V to 3.6 V | 3.0 V to 3.6 V | Both parts share the same supply window, so power-rail design and decoupling requirements remain compatible. |
| Package / Pin Count | 24-Lead LFCSP | 24-Lead LFCSP | Identical package and pinout allow a drop-in footprint replacement without PCB redesign. |
| Output Type | Differential (complementary) outputs | Differential (complementary) outputs | Matching output topology ensures the downstream mixer or buffer interface remains compatible. |
| Programmable Divider / Charge Pump | Integer-N with programmable charge pump currents | Integer-N with programmable charge pump currents | Same architecture means loop filter and register programming are largely transferable between the two parts. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Identical temperature ratings confirm both parts suit the same environmental conditions. |
| Target Application Band | ~1.9 GHz band (e.g., PCS/DCS) | ~2.1–2.4 GHz band (e.g., WCDMA/ISM) | The intended band differs, so functional substitutability depends on whether the system operates within the overlapping frequency window. |

Frequently asked questions
What are the key differences between the ADF4360-2BCPZ and the ADF4360-1BCPRL?
The ADF4360-2BCPZ and ADF4360-1BCPRL are both integrated integer-N synthesizers with VCOs from Analog Devices, but they differ in frequency range and packaging. The ADF4360-2BCPZ covers a VCO output range of 1850 MHz to 2170 MHz, while the ADF4360-1BCPRL covers 2050 MHz to 2450 MHz. The ADF4360-2BCPZ is supplied in a 24-lead LFCSP package, whereas the ADF4360-1BCPRL is supplied in a 24-lead LFCSP in tape and reel packaging.
Are the ADF4360-2BCPZ and ADF4360-1BCPRL pin-compatible?
Yes. Both devices are members of the ADF4360 family and share the same 24-lead LFCSP pinout and package footprint, so they are pin-compatible. However, because their VCO frequency ranges differ, they are not electrically interchangeable without verifying that the target frequency band is covered.
What is the VCO frequency range of each device?
The ADF4360-2BCPZ has an integrated VCO output range of 1850 MHz to 2170 MHz. The ADF4360-1BCPRL has an integrated VCO output range of 2050 MHz to 2450 MHz. Both ranges are specified in the respective Analog Devices datasheets.
What is the difference between the BCPZ and BCPRL suffixes?
The BCPZ suffix indicates a 24-lead LFCSP package in a tray or tube format, while the BCPRL suffix indicates the same 24-lead LFCSP package supplied in tape and reel for automated assembly. The silicon die and electrical specifications are otherwise the same within each respective part number.
Can the ADF4360-2BCPZ be used as a drop-in replacement for the ADF4360-1BCPRL?
Not directly. Although the packages and pinouts are compatible, the VCO frequency ranges differ. The ADF4360-2BCPZ covers 1850 MHz to 2170 MHz, while the ADF4360-1BCPRL covers 2050 MHz to 2450 MHz. A replacement is only valid if the required output frequency falls within the overlapping 2050 MHz to 2170 MHz band and all other specifications are verified against the datasheets.
What supply voltage and current consumption do these synthesizers require?
Both the ADF4360-2BCPZ and ADF4360-1BCPRL operate from a 3.0 V to 3.6 V supply. Typical current consumption is approximately 45 mA for the RF output stage and VCO, with additional current for the digital and charge pump sections as specified in the Analog Devices datasheet. Designers should consult the datasheet for exact test conditions.
What is the phase noise performance of these devices?
Both devices are specified with a normalized phase noise floor of approximately -219 dBc/Hz in the datasheet. Actual in-band phase noise depends on the PLL loop filter, charge pump current, and reference frequency. Designers should refer to the Analog Devices datasheet for phase noise plots at specific output frequencies.
What package and operating temperature range do these parts support?
Both the ADF4360-2BCPZ and ADF4360-1BCPRL are offered in a 24-lead LFCSP package and are specified for operation over the -40°C to +85°C industrial temperature range, as stated in the Analog Devices datasheet.
