ADF4360-3BCPRL

Overview

The ADF4360-3 is a fully integrated integer-N synthesizer and voltage controlled oscillator (VCO) designed for a center frequency of 1750 MHz. It operates within an output frequency range of 1600 MHz to 1950 MHz, with a divide-by-2 option providing 800 MHz to 975 MHz. The device functions on a 3.0 V to 3.6 V power supply and features a 3-wire serial interface. Key electrical specifications include a typical phase noise of -110 dBc/Hz at 100 kHz offset and a programmable output power level ranging from -12 dBm to -3 dBm.

Feature Summary

• Integrated integer-N synthesizer and VCO covering 1600 MHz to 1950 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
• Programmable output power levels (-12 dBm to -3 dBm) via control latch

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and tape/reel configuration. Ensure compatibility with the required operating temperature range of -40°C to +85°C. Confirm that the design supports the necessary 3-wire serial interface timing requirements for CLK, DATA, and LE signals.

Selection Notes

Select the appropriate prescaler setting (8/9, 16/17, or 32/33) based on the desired division ratio and reference frequency. Configure the charge pump current using the RSET resistor to match loop filter requirements. Adjust the output stage tail current to balance power consumption and RF output power needs.

Part Context

The ADF4360-3 belongs to the ADF4360 family of frequency synthesizers. It is specifically optimized for the 1.6 GHz to 1.95 GHz band, distinguishing it from other variants in the series that target different frequency ranges such as 2.4 GHz or 1.1 GHz bands.

Replacement Considerations

Direct replacements within the same family include ADF4360-0, ADF4360-1, ADF4360-4, and ADF4360-5. Note that these alternatives cover different frequency ranges and may require circuit redesign for impedance matching and filtering.
