ADF4152HVBCPZ-RL7

Overview

The ADF4152HVBCPZ-RL7 is a high voltage fractional-N and integer-N PLL synthesizer from Analog Devices, operating up to 5.0 GHz. It features an integrated high voltage charge pump supporting VP supplies from 6.0 V to 30 V, enabling direct drive of wideband VCOs without operational amplifiers. The device operates on a 3.0 V to 3.6 V logic supply with a typical current consumption of 50 mA. Key specifications include a programmable output divider (÷1/÷2/÷4/÷8/÷16), RF input frequencies up to 5.0 GHz, and a normalized in-band phase noise floor of -213 dBc/Hz in low noise mode. It utilizes a 3-wire serial interface for register control.

Feature Summary

• Integrated high voltage charge pump supports VP ranges from 6.0 V to 30 V for direct VCO tuning.
• Fractional-N and Integer-N synthesis capabilities with RF bandwidth up to 5.0 GHz.
• Programmable dual-modulus prescaler and output dividers (÷1, ÷2, ÷4, ÷8, ÷16).
• Low power consumption with sleep mode capability and software-controlled RF mute function.

Applications

• Wireless infrastructure systems
• Microwave point-to-point and point-to-multipoint radios
• Very small aperture terminal (VSAT) radios
• Test equipment requiring precise frequency synthesis

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to the reel packaging configuration as indicated by the manufacturer's part number structure. Confirm that the LFCSP-32 package exposed pad connection requirements are met during PCB assembly to ensure proper thermal dissipation and grounding. Check for any updated revision notes regarding the 32-bit shift register timing characteristics before finalizing design implementation.

Selection Notes

Select this component when applications require driving high-voltage VCOs directly without external active filtering. Ensure the required RF input frequency does not exceed 5.0 GHz and that the charge pump voltage supply can be maintained within the 6.0 V to 30 V range. Consider the 3-wire serial interface compatibility with the host processor and verify that the 32-bit data word format aligns with the system's communication protocol.

Part Context

This part belongs to the ADF4152HV series of high voltage PLL synthesizers. It shares functional similarities with other devices in the family but is distinguished by its specific high voltage charge pump capabilities and 5.0 GHz RF input range. The BCPSZ-RL7 designation indicates the lead-free, tape and reel packaging variant manufactured by Analog Devices Inc.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Designers should consult Analog Devices for cross-reference information or evaluate alternative high voltage PLL synthesizers based on specific voltage and frequency requirements.
