ADF4360-8BCP

Overview

The ADF4360-8BCP 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, determined by external inductors connected to the 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, including CLK, DATA, and LE inputs. Key specifications include a programmable output power level ranging from -9 dBm to 0 dBm, digital lock detect functionality, and hardware/software power-down modes for energy efficiency.

Feature Summary

• Integrated Integer-N Synthesizer and VCO with 65 MHz to 400 MHz output range
• 3-wire serial interface (CLK, DATA, LE) for register control
• Programmable output power levels (-9 dBm to 0 dBm)
• Digital lock detect and Mute-Till-Lock Detect (MTLD) feature

Applications

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

Procurement Notes

Verify the package type matches the required footprint, as the BCP suffix indicates a Chip Scale Package (CSP). Confirm that the specific revision (Rev. A datasheet) aligns with the manufacturing date code of the supplied components. Ensure ESD precautions are observed during handling due to the high-performance RF nature of the integrated circuit.

Selection Notes

Select appropriate external inductors for the L1 and L2 pins to set the desired center frequency within the 65 MHz to 400 MHz range. The choice of inductance affects VCO sensitivity and phase noise performance. Ensure the reference input frequency (REFIN) falls within the specified 10 MHz to 250 MHz range and that the RSET resistor is chosen to achieve the desired charge pump current.

Part Context

The ADF4360-8BCP belongs to the ADF4360 family of integrated synthesizers. This family includes variants such as the ADF4360-0, ADF4360-2, and others, which differ primarily in their output frequency ranges and internal VCO configurations. The ADF4360-8 specifically targets the lower frequency band up to 400 MHz, distinguishing it from higher-frequency counterparts in the same product line.

Replacement Considerations

Direct replacements within the ADF4360 family must be verified for compatible frequency ranges. For instance, the ADF4360-5 covers 1200 MHz to 1400 MHz and is not a direct functional substitute for the 65–400 MHz range of the ADF4360-8. Cross-model substitution requires careful evaluation of inductor requirements and pinout compatibility.
