ADF4212LBCPZ

Overview

The ADF4212LBCPZ-RL7 is a dual low-power Integer-N PLL frequency synthesizer from Analog Devices, housed in a 20-lead LFCSP package. It integrates two independent synthesizers for RF and IF local oscillator generation. Key electrical parameters include a total supply current of 7.5 mA at 3 V, operating voltage range of 2.7 V to 3.3 V, and input frequencies up to 2.4 GHz (RF) and 1.0 GHz (IF). The device features programmable charge pump currents, separate VP supplies for extended tuning, and a 3-wire serial interface.

Feature Summary

• Dual synthesizer architecture supporting simultaneous RF and IF local oscillator generation
• Low power consumption with 7.5 mA typical current draw and dedicated power-down mode
• Programmable dual modulus prescaler options: 8/9, 16/17, 32/33, or 64/65
• Integrated analog and digital lock detect functions with multiplexed output access

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging quantity of 1500 units as indicated by distributor specifications. Confirm that the LFCSP-20 package variant matches the required thermal pad soldering guidelines for optimal heat dissipation during assembly.

Selection Notes

Select this component when a single IC must provide both RF and IF local oscillators to save board space. Ensure the external VCO tuning voltage does not exceed the VP pin maximum rating of 5.5 V. Verify that the required reference frequency falls within the 10 MHz to 150 MHz input range for proper PFD operation.

Part Context

This part belongs to the ADF4212L family of dual synthesizers. The BCPSZ suffix indicates the Lead Frame Chip Scale Package (LFCSP) form factor, distinct from the TSSOP-20 package used in variants like the ADF4212LBRUZ. Both packages share identical internal circuitry and electrical specifications.

Replacement Considerations

ADF4212LBRUZ-RL7 offers identical functionality in a 20-TSSOP package.
