ADF4213BCPZ

Overview

The ADF4213BCPZ is a dual RF/IF PLL frequency synthesizer from Analog Devices, designed for local oscillator implementation in wireless transceivers. It integrates two independent synthesizers with separate charge pumps and prescalers. The RF section supports input frequencies up to 3.0 GHz, while the IF section operates up to 1.0 GHz. Powered by a 2.7 V to 5.5 V supply, it features programmable dual modulus prescalers (8/9, 16/17, 32/33, 64/65) and a 3-wire serial interface. Typical current consumption is 15 mA with both sections active at 3 V. The device includes analog and digital lock detect functions, Fastlock mode, and power-down capabilities.

Feature Summary

• Dual synthesizer architecture supporting RF inputs up to 3.0 GHz and IF inputs up to 1.0 GHz
• Programmable dual modulus prescaler options: 8/9, 16/17, 32/33, and 64/65
• Separate charge pump supplies (VP1, VP2) allow extended tuning voltage up to 6.0 V
• Integrated analog and digital lock detect with multiplexer output access

Applications

• Base stations for wireless radio systems including GSM, PCS, DCS, CDMA, and WCDMA
• Wireless handsets and mobile communication devices
• Wireless LAN infrastructure components
• Communications test equipment signal generation
• CATV equipment local oscillators

Procurement Notes

Verify the package option CP-20 corresponds to the Chip Scale Package variant. Confirm the B version suffix indicates an operating temperature range of -40 °C to +85 °C. Ensure ESD precautions are observed during handling due to the device's sensitivity. Check for RoHS compliance status if required by specific manufacturing standards.

Selection Notes

Select the ADF4213BCPZ when RF frequencies up to 3.0 GHz are required, distinguishing it from lower-frequency variants like the ADF4210 or ADF4211. Ensure the external VCO tuning voltage does not exceed the maximum VP rating of 6.0 V. Verify that the reference input frequency requirements align with the CMOS-compatible REFIN pin specifications.

Part Context

The ADF4213BCPZ belongs to the ADF4210/ADF4211/ADF4212/ADF4213 family of dual frequency synthesizers. It shares the same functional block diagram and control interface as its siblings but offers higher RF performance limits. The BC prefix denotes the Chip Scale Package (CP-20), while the RU suffix indicates the TSSOP package.

Replacement Considerations

Direct replacements within the same family include ADF4210BCP, ADF4211BCP, and ADF4212BCP, provided their lower RF frequency limits meet application requirements. Cross-package equivalents such as ADF4213BRU offer identical functionality in a TSSOP-20 housing.
