ADF4213BRU

Overview

The ADF4213BRU is a dual RF/IF PLL frequency synthesizer from Analog Devices, housed in a 20-lead Thin Shrink Small Outline Package (TSSOP). It 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. The device operates on a 2.7 V to 5.5 V power supply with a typical current consumption of 15 mA for the RF section and 4.5 mA for the IF section. Key features include programmable dual modulus prescalers, a 3-wire serial interface, and separate charge pump supplies for extended tuning voltage capabilities.

Feature Summary

• Dual synthesizer architecture supporting independent RF and IF sections
• RF input frequency range up to 3.0 GHz
• Programmable dual modulus prescaler options: 8/9, 16/17, 32/33, or 64/65
• Separate charge pump supply pins (VP1, VP2) allow tuning voltages up to 6 V

Applications

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

Procurement Notes

Verify the specific ordering suffix RU-20 corresponds to the TSSOP-20 package variant. Confirm the temperature grade B version covers the required -40 °C to +85 °C operating range. Ensure ESD precautions are observed during handling due to the device's sensitivity. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity.

Selection Notes

Select the ADF4213BRU when an RF output frequency up to 3.0 GHz is required. Compare against the ADF4212 if the maximum frequency requirement is lower at 2.7 GHz. Consider the separate VP supply pins if the system requires a tuning voltage exceeding the main VDD rail. Verify that the 3-wire serial interface compatibility matches the host controller's digital logic levels.

Part Context

The ADF4213 is part of the ADF4210/ADF4211/ADF4212/ADF4213 family of dual frequency synthesizers. These devices share a common functional block diagram and register map, differing primarily in their maximum RF input frequency specifications. The BRU suffix denotes the industrial temperature range and TSSOP packaging option within this product line.

Replacement Considerations

The ADF4212BRU serves as a compatible alternative if the application does not require RF frequencies above 2.7 GHz. Both components share identical pinouts, package types, and control interfaces, facilitating direct substitution in designs where the higher frequency capability of the ADF4213 is unnecessary.
