ADF4360-2BCP

Overview

The ADF4360-2BCP is a fully integrated integer-N frequency synthesizer and voltage-controlled oscillator (VCO) designed for a center frequency of 2000 MHz. It operates within an output frequency range of 1850 MHz to 2170 MHz, with a divide-by-2 option providing 925 MHz to 1085 MHz. The device supports a 3-wire serial interface and functions on a 3.0 V to 3.6 V power supply. Key electrical specifications include a typical phase noise of -110 dBc/Hz at 100 kHz offset and a programmable charge pump current ranging from 0.312 mA to 2.5 mA.

Feature Summary

• Integrated Integer-N Synthesizer and VCO covering 1850 MHz to 2170 MHz
• Programmable Dual-Modulus Prescaler options: 8/9, 16/17, or 32/33
• Analog and Digital Lock Detect capabilities with MUXOUT access
• Hardware and Software Power-Down modes for low power consumption

Applications

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

Procurement Notes

Verify the specific suffix 'BCP' against the manufacturer's ordering guide to confirm package type and temperature grade. Ensure compatibility with the required logic levels, as the device supports 1.8 V logic compatibility. Confirm that the design accounts for the exposed pad connection to AGND for proper thermal and electrical performance.

Selection Notes

Select this component when a fixed center frequency near 2 GHz is required. The B version specifies the operating temperature range from -40°C to +85°C. Designers must choose the appropriate prescaler setting (8/9, 16/17, or 32/33) based on the desired division ratio and reference frequency to ensure contiguous frequency coverage.

Part Context

The ADF4360-2 belongs to the ADF4360 family of PLL frequency synthesizers. It is specifically optimized for L-band applications, such as satellite receivers and wireless communications. The device integrates the VCO core, phase detector, charge pump, and counters into a single chip, reducing external component count compared to discrete solutions.

Replacement Considerations

Check the manufacturer's cross-reference list for direct replacements. Other variants in the ADF4360 series may offer different frequency ranges or features but require verification of pinout and register compatibility.
