ADF4213BRUZ

Overview

The ADF4213BRUZ is a dual RF/IF PLL frequency synthesizer from Analog Devices, housed in a 20-lead TSSOP package. It integrates two independent phase-locked loops for local oscillator generation in wireless transceivers. The device supports an RF input frequency range of 0.2 GHz to 3.0 GHz and an IF input range of 60 MHz to 1.0 GHz. Operating on a single supply voltage between 2.7 V and 5.5 V, it features separate charge pump supplies (VP) to extend tuning voltage capabilities. Key electrical parameters include a maximum phase detector frequency of 55 MHz, programmable charge pump currents up to 5 mA, and a typical power consumption of 15 mA at 3 V with both loops active.

Feature Summary

• Dual independent PLLs supporting RF frequencies up to 3.0 GHz and IF frequencies up to 1.0 GHz
• Programmable dual-modulus prescaler with options for 8/9, 16/17, 32/33, or 64/65 division ratios
• Separate charge pump supply pins (VP1, VP2) allow extended VCO tuning voltages up to 6 V in 3 V systems
• Integrated analog and digital lock detect circuits with multiplexed output access via MUXOUT pin

Applications

• Base stations for wireless radio standards including GSM, PCS, DCS, CDMA, and WCDMA
• Wireless handsets and mobile communication devices
• Wireless LAN infrastructure equipment
• Communications test and measurement instruments
• CATV equipment requiring stable local oscillators

Procurement Notes

Verify the specific suffix 'BRUZ' corresponds to the industrial temperature grade (-40°C to +85°C) and TSSOP-20 package configuration as listed in the ordering guide. Confirm that the source documentation explicitly identifies this part number variant before procurement, as suffixes may indicate packaging or temperature variations not detailed in general family descriptions.

Selection Notes

Select the ADF4213BRUZ when the application requires an RF output frequency up to 3.0 GHz, distinguishing it from the lower-frequency ADF4210, ADF4211, and ADF4212 variants. Ensure the external VCO tuning voltage requirements are met by utilizing the separate VP supply pins if the system operates at 3 V but requires higher tuning ranges. Verify that the required reference frequency and division ratios fit within the 14-bit R-counter and 12-bit B-counter limits.

Part Context

The ADF4213 is part of the ADF4210/ADF4211/ADF4212/ADF4213 family of dual frequency synthesizers. While sharing identical architecture and control interfaces, the ADF4213 is distinguished by its higher RF input frequency capability, extending up to 3.0 GHz compared to 1.2 GHz for the ADF4210 and 2.7 GHz for the ADF4212. All members utilize the same RU-20 TSSOP or CP-20 CSP packages and operate under similar power and interface specifications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided datasheet. Designers should verify compatibility with existing ADF421x family members (ADF4210, ADF4211, ADF4212) only if the RF frequency requirement does not exceed their respective maximum limits.
