ADF4213BCP

Overview

The ADF4213BCP is a dual RF/IF PLL frequency synthesizer in a 20-lead Chip Scale Package (CP-20). It integrates two independent synthesizers for local oscillator generation in wireless transceivers. The RF section supports input frequencies from 0.2 GHz to 3.0 GHz, while the IF section covers 60 MHz to 1.0 GHz. Operating on a 2.7 V to 5.5 V supply, it features programmable dual modulus prescalers (8/9, 16/17, 32/33, 64/65), separate charge pump supplies for extended tuning voltage, and a 3-wire serial interface. Typical power consumption is 15 mA with both sections active.

Feature Summary

• Dual synthesizers: RF (0.2–3.0 GHz) and IF (60 MHz–1.0 GHz)
• Programmable dual modulus prescaler options: 8/9, 16/17, 32/33, 64/65
• Separate charge pump supplies (VP1, VP2) allow up to 6.0 V tuning in 3 V systems
• Integrated analog and digital lock detect with MUXOUT access

Applications

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

Procurement Notes

Verify package type CP-20 corresponds to the Chip Scale Package variant. Confirm temperature range is Industrial (-40°C to +85°C). Check datasheet for chip availability status as noted in the ordering guide. Ensure ESD precautions are observed during handling due to sensitivity.

Selection Notes

Select ADF4213BCP when RF inputs up to 3.0 GHz are required. Compare against ADF4213BRU if TSSOP packaging is preferred over CSP. Verify that the required prescaler division ratio (e.g., 8/9 vs 16/17) matches the system's frequency planning constraints relative to the maximum prescaler output frequency of 200 MHz at 5 V.

Part Context

The ADF4213BCP belongs to the ADF4210/ADF4211/ADF4212/ADF4213 family of dual frequency synthesizers. It shares the same functional block diagram and control interface as other variants in the series, differing primarily in maximum operating frequencies and package style. The 'BCP' suffix specifically denotes the Chip Scale Package option.

Replacement Considerations

ADF4213BRU offers identical electrical performance in a TSSOP-20 package. Other family members (ADF4210, ADF4211, ADF4212) have lower maximum frequency limits.
