ADF4360-4BCPZ

Overview

The ADF4360-4BCPZ is a fully integrated integer-N frequency synthesizer and voltage-controlled oscillator (VCO) designed for a center frequency of 1600 MHz. It operates within an output frequency range of 1450 MHz to 1750 MHz, with a divide-by-2 option providing 725 MHz to 875 MHz. The device supports a 3-wire serial interface, programmable dual-modulus prescaler (8/9, 16/17, 32/33), and adjustable output power levels from -13 dBm to -4 dBm. Powered by a 3.0 V to 3.6 V supply, it features analog and digital lock detect, hardware/software power-down modes, and 1.8 V logic compatibility.

Feature Summary

• Integrated Integer-N Synthesizer and VCO covering 1450 MHz to 1750 MHz
• Programmable Dual-Modulus Prescaler: 8/9, 16/17, or 32/33
• Adjustable Output Power Levels: -13 dBm to -4 dBm in 3 dB steps
• Dual Lock Detect: Digital (active high) and Analog (open-drain)
• Low Power Sleep Mode: 7 µA typical current consumption

Applications

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

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's ordering guide to confirm package type and temperature grade. Confirm that the B-version specifications align with design requirements, particularly regarding charge pump current settings and prescaler options. Ensure ESD precautions are observed during handling due to the sensitivity of the RF integrated circuit.

Selection Notes

Select the ADF4360-4BCPZ when a fixed L-band frequency around 1600 MHz is required without external VCO tuning complexity. Consider the divide-by-2 feature if lower frequencies near 800 MHz are needed. Evaluate the programmable output power to balance between transmission range and power consumption. Verify that the 3-wire serial interface timing constraints meet the system controller's capabilities.

Part Context

The ADF4360-4 belongs to the ADF4360 family of integrated synthesizers. It is specifically optimized for L-band applications, distinguishing itself from other variants like the ADF4360-1 (2.0–2.45 GHz) or ADF4360-3 (1.6–1.95 GHz). The BCPZ designation indicates a Lead-Free Chip Scale Package (CSP) suitable for surface-mount assembly.

Replacement Considerations

Direct replacements within the same family include ADF4360-1BCPZ, ADF4360-2BCPZ, and ADF4360-3BCPZ, provided their respective frequency ranges match the application needs. Cross-family alternatives such as the ADF4351 series offer wider frequency coverage but may require different loop filter designs and control interfaces.
