ADF4360-8BCPZ

Overview

The ADF4360-8BCPZ is an integrated integer-N synthesizer and voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 65 MHz to 400 MHz, with the center frequency determined by external inductors connected to L1 and L2 pins. The device supports a power supply voltage between 3.0 V and 3.6 V and features 1.8 V logic compatibility. Control is managed via a simple 3-wire serial interface. Key specifications include a typical phase noise of -120 dBc/Hz at 100 kHz offset and programmable output power levels ranging from -9 dBm to 0 dBm.

Feature Summary

• Integrated Integer-N Synthesizer and VCO covering 65 MHz to 400 MHz
• Programmable Output Power Levels (-9 dBm to 0 dBm)
• Digital Lock Detect and Mute-Till-Lock Detect (MTLD) functionality
• Hardware and Software Power-Down Modes

Applications

• System clock generation
• Test equipment
• Wireless LANs
• CATV equipment

Procurement Notes

Verify the specific suffix BCPZ corresponds to the LFCSP-24 package and commercial temperature range (-40°C to +85°C). Confirm that external inductors are selected to achieve the desired operating frequency band, as the internal VCO range relies on these components. Ensure the design accounts for the 3.0 V to 3.6 V supply requirements and proper decoupling of AVDD, DVDD, and VVCO pins.

Selection Notes

Select appropriate external inductors for L1 and L2 to set the target frequency, noting that L1 and L2 must be identical values. Consider the required output power level when configuring the PL1 and PL2 bits, as this affects current consumption. Evaluate the phase detector frequency and loop bandwidth requirements against the charge pump current settings (ICP) to ensure stability and lock time performance.

Part Context

The ADF4360-8 is part of the ADF4360 family of frequency synthesizers. It shares architectural similarities with other variants like the ADF4360-4 and ADF4360-7 but is specifically optimized for the lower frequency range of 65 MHz to 400 MHz. This makes it distinct from higher-frequency counterparts in the same series.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for potential cross-references or newer generations of frequency synthesizers if availability is a concern.
