ADF4113BCPZ

Overview

The ADF4113BCPZ is an RF PLL frequency synthesizer from Analog Devices, designed for local oscillator implementation in wireless systems. It supports a maximum RF input frequency of 4.0 GHz and operates on a single 2.7 V to 5.5 V supply. Key specifications include a programmable dual-modulus prescaler (8/9, 16/17, 32/33, or 64/65), a low-noise digital phase-frequency detector, and a precision charge pump with currents up to 5 mA. The device features a 3-wire serial interface, hardware/software power-down modes, and analog/digital lock detect outputs.

Feature Summary

• Maximum RF input frequency of 4.0 GHz
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, 64/65
• Single 2.7 V to 5.5 V power supply operation
• Integrated low-noise PFD and precision charge pump

Applications

• Base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
• Communications test equipment

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's ordering guide to confirm package type (LFCSP) and temperature grade (Industrial). Ensure compatibility with required PCB design guidelines for chip-scale packages, particularly regarding exposed paddle soldering for thermal management and ground connection.

Selection Notes

Select this component when a 4.0 GHz upper limit is required. Compare against ADF4112 (3.0 GHz) if lower frequencies suffice. Consider the separate VP pin requirement for extended tuning voltage in 3 V systems. Verify that the programmable prescaler division ratios meet the specific N-divider requirements of the target application.

Part Context

This part belongs to the ADF4110 family, which includes the ADF4110 (550 MHz), ADF4111 (1.2 GHz), and ADF4112 (3.0 GHz). All members share similar architectures and interfaces but differ in maximum operating frequencies. The ADF4113 provides the highest frequency capability within this specific series.

Replacement Considerations

ADF4112BCPZ offers identical functionality with a reduced maximum RF input frequency of 3.0 GHz.
