ADF4212LBRUZ-RL7

Overview

The ADF4212LBRUZ-RL7 is a dual low-power Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It integrates two independent synthesizers for RF and IF sections, supporting input frequencies up to 2.4 GHz (RF) and 1.0 GHz (IF). The device operates on a 2.7 V to 3.3 V supply with a typical current consumption of 7.5 mA. Key features include programmable dual modulus prescalers (8/9, 16/17, 32/33, 64/65), adjustable charge pump currents, and separate VP supplies for extended tuning voltage ranges. It utilizes a 3-wire serial interface and offers fastlock and power-down modes.

Feature Summary

• Dual synthesizer architecture with separate RF (up to 2.4 GHz) and IF (up to 1.0 GHz) paths
• Low power consumption: 7.5 mA typical total current at 3 V supply
• Programmable dual modulus prescaler options: 8/9, 16/17, 32/33, or 64/65
• Separate VP1 and VP2 pins allow charging pump voltages up to 5.5 V for wide-range VCO tuning

Applications

• Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
• Base stations for wireless radio systems
• Cable TV tuners (CATV)

Procurement Notes

Verify the component against the official Analog Devices ADF4212L datasheet (Rev. E) to confirm pinout compatibility and electrical specifications. Ensure that the ordering suffix RL7 corresponds to the required tape and reel packaging format for automated assembly processes.

Selection Notes

Select this component when a single IC solution is required for both RF and IF local oscillator generation in dual-conversion architectures. Verify that the external VCO tuning voltage requirements do not exceed the 5.5 V limit supported by the VP1 and VP2 pins. Confirm that the desired reference frequency falls within the 10 MHz to 150 MHz range specified for the REFIN input.

Part Context

This part belongs to the ADF4212L family of dual frequency synthesizers. The BRUZ suffix indicates a 20-lead TSSOP surface-mount package. The -RL7 suffix denotes the specific reel packaging configuration used for high-volume manufacturing.

Replacement Considerations

The ADF4212BRUZ-RL is a related variant within the same product family. Verify functional equivalence regarding pinout and electrical parameters before substitution.
