ADF4110BCPZ-RL

Overview

The ADF4110BCPZ-RL is a single-channel, integer-N RF PLL frequency synthesizer from Analog Devices. It operates with an input frequency range of 50 MHz to 550 MHz and supports power supplies from 2.7 V to 5.5 V. The device features a low-noise digital phase-frequency detector, a precision charge pump, and a programmable dual-modulus prescaler. It includes a 14-bit reference divider, 6-bit A counter, and 13-bit B counter for flexible frequency synthesis. Controlled via a 3-wire serial interface, it consumes 4.5 mA typical current and is housed in a 20-lead LFCSP package.

Feature Summary

• Integrated integer-N PLL with 550 MHz maximum RF input frequency
• Programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65)
• Separate charge pump supply (VP) allows extended tuning voltage up to 6.0 V
• Low noise digital PFD and precision charge pump with programmable current

Applications

• Local oscillators for wireless base stations (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless handsets and mobile communication devices
• Wireless LAN infrastructure components
• Communications test and measurement equipment

Procurement Notes

Verify the specific suffix RL indicates reel packaging when sourcing. Confirm the B version designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure compatibility with the 20-lead LFCSP footprint during procurement planning. Check for moisture sensitivity level requirements prior to assembly.

Selection Notes

Select this component for applications requiring a 550 MHz upper limit. Compare against ADF4111, ADF4112, and ADF4113 if higher frequency operation is needed. Ensure the external VCO tuning voltage range is compatible with the VP pin capability. Verify that the required division ratios fit within the A and B counter bit limits.

Part Context

This part belongs to the ADF4110 family, which also includes the ADF4111, ADF4112, and ADF4113. These devices share similar architectures but differ in maximum operating frequencies. The ADF4110 is the lowest frequency variant in this series, optimized for sub-600 MHz applications.

Replacement Considerations

ADF4111BCPZ-RL offers a 1.2 GHz input range. ADF4112BCPZ-RL supports up to 3.0 GHz. ADF4113BCPZ-RL supports up to 4.0 GHz. All variants share the same LFCSP-20 package and register interface.
