ADF4360-6BCP

Overview

The ADF4360-6BCP is an integrated integer-N synthesizer and voltage-controlled oscillator (VCO) designed for a center frequency of 1150 MHz. It operates within an output frequency range of 1050 MHz to 1250 MHz and supports a divide-by-2 option for outputs between 525 MHz and 625 MHz. The device functions on a 3.0 V to 3.6 V power supply with 1.8 V logic compatibility. Key electrical parameters include a typical phase noise of -110 dBc/Hz at 100 kHz offset, a programmable charge pump current ranging from 0.312 mA to 2.5 mA, and a reference input frequency range of 10 MHz to 250 MHz. It features a 3-wire serial interface and analog/digital lock detect capabilities.

Feature Summary

• Integrated integer-N synthesizer and VCO covering 1050 MHz to 1250 MHz
• Programmable dual-modulus prescaler options: 8/9, 16/17, or 32/33
• Low phase noise performance: -110 dBc/Hz typ at 100 kHz offset
• Hardware and software power-down modes with low sleep current

Applications

• Wireless handsets (DECT, GSM, PCS, DCS, WCDMA)
• Test equipment
• Wireless LANs
• CATV equipment

Procurement Notes

Verify the specific suffix BCPZ against the ordering guide to confirm package type and RoHS compliance. Ensure the design accounts for the exposed pad connection to AGND as specified in the pin configuration. Confirm that the 3-wire serial interface timing requirements are met by the host controller.

Selection Notes

Select the appropriate dual-modulus prescaler setting (8/9, 16/17, or 32/33) based on the required VCO frequency and reference divider values. Choose the core power level (5 mA to 20 mA) and output power level (-13.5 dBm to -4.5 dBm) to balance power consumption and signal strength. Ensure the RSET resistor value is selected correctly to set the desired charge pump current.

Part Context

The ADF4360-6 is part of the Analog Devices ADF4360 family of fully integrated frequency synthesizers. This specific variant is optimized for the 1150 MHz band, distinguishing it from other family members designed for different frequency ranges such as 1600 MHz or 2500 MHz. It shares common architectural features like the 24-bit shift register and programmable counters across the series.

Replacement Considerations

Direct replacements within the same family require matching the output frequency range. For example, the ADF4360-5 covers 1150–1400 MHz, while the ADF4360-3 covers 1600–1950 MHz. Verify pin compatibility and register settings when substituting with other ADF4360 variants.
