ADF4211BCP

Overview

The ADF4211BCP is a single-channel, integer-N phase-locked loop (PLL) frequency synthesizer manufactured by Analog Devices Inc. It operates within an output frequency range of 35 MHz to 2.7 GHz and supports reference input frequencies up to 200 MHz. The device functions on a single supply voltage ranging from 2.7 V to 5.5 V, with a typical operating current of 11.5 mA. Packaged in a 20-lead LFCSP, it integrates a low-noise charge pump and a programmable dual-modulus prescaler for precise frequency generation.

Procurement Notes

Verify the specific suffix against official documentation, as packaging variations such as reel or tray configurations may exist within the product family. Confirm lead times and availability directly with authorized distributors, as stock levels fluctuate. Ensure the component meets required environmental specifications for the intended deployment environment.

Selection Notes

Select this component when a single-loop integer-N solution is sufficient for the target frequency synthesis requirements. Verify that the maximum reference frequency of 200 MHz aligns with the system clock source. Consider power consumption constraints, as the device draws approximately 11.5 mA at 5 V. Evaluate package compatibility if transitioning from older SOIC or TSSOP variants.

Part Context

This part belongs to the ADF4211 series of integer-N PLLs, designed for general-purpose frequency synthesis applications. It serves as a foundational building block for RF front-ends requiring stable local oscillator signals. The BCP variant indicates a specific thermal and mechanical package configuration within the Analog Devices portfolio.

Replacement Considerations

Direct replacements include other members of the ADF421x family, such as the ADF4212 for dual-loop requirements or the ADF4218L for lower power consumption. Verify pinout compatibility and electrical parameter overlaps before substitution.
