ADF41513BCPZ

Overview

The ADF41513BCPZ is a high-performance frequency synthesizer manufactured by Analog Devices Inc., designed for local oscillator generation in wireless systems. It operates within a bandwidth of 1 GHz to 26.5 GHz using an external VCO and loop filter. The device supports both Integer N and Fractional-N PLL modes, achieving an ultralow normalized phase noise floor of −235 dBc/Hz in Integer mode and −231 dBc/Hz in Fractional mode. It features a maximum Phase Frequency Detector (PFD) frequency of 250 MHz for Integer N and 125 MHz for Fractional N operation. Power supply requirements are met with AVDDx and VP rails at 3.3 V ± 5%, drawing a total current of approximately 128.8 mA under typical conditions.

Feature Summary

• Ultralow noise performance with a normalized phase noise floor of −235 dBc/Hz (Integer N) and −231 dBc/Hz (Fractional N).
• Wide operating bandwidth from 1 GHz to 26.5 GHz, eliminating the need for frequency doublers or dividers.
• High-speed PFD supporting up to 250 MHz in Integer N mode and 125 MHz in Fractional N mode.
• Flexible modulus options including a 25-bit fixed modulus and a 49-bit variable modulus for sub-Hertz resolution.

Applications

• Test equipment and instrumentation
• Wireless infrastructure
• Microwave point-to-point and multipoint radios
• Very small aperture terminal (VSAT) radios
• Aerospace and defense

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific package variant matches the required PCB footprint. Ensure proper ESD handling procedures are followed during assembly due to the sensitivity of the RF integrated circuit. Check for moisture sensitivity levels if storage duration exceeds specified limits.

Selection Notes

Select this component when applications require ultra-low phase noise at frequencies up to 26.5 GHz. The choice between 25-bit fixed and 49-bit variable modulus depends on the required frequency resolution and spur performance. Ensure the external VCO input sensitivity aligns with the ADF41513's output drive capabilities. Verify that the system power budget accommodates the total current consumption of approximately 128.8 mA.

Part Context

The ADF41513 belongs to the ADF415xx series of PLL synthesizers from Analog Devices. It utilizes a silicon germanium (SiGe) BiCMOS process to achieve superior noise characteristics compared to standard CMOS technologies. This family is targeted at high-frequency microwave applications where spectral purity and wide tuning ranges are critical design constraints.
