ADF4113HVBRUZ-RL

Overview

The ADF4113HVBRUZ-RL is an integer-N frequency synthesizer featuring a high voltage charge pump capable of 15 V output. Designed for use with voltage-controlled oscillators (VCOs) requiring high tuning voltages, it operates directly with passive loop filters. The device integrates a low-noise digital phase frequency detector, programmable reference divider, dual-modulus prescaler, and A/B counters. It supports RF input frequencies from 200 MHz to 4.0 GHz and functions on power supplies ranging from 2.7 V to 5.5 V for logic/analog sections, while the charge pump supply (VP) ranges from 13.5 V to 16.5 V.

Feature Summary

• High voltage charge pump delivering up to 15 V for direct drive of high-tuning-voltage VCOs
• RF frequency range of 200 MHz to 4.0 GHz with dual-modulus prescaler options (8/9, 16/17, 32/33, 64/65)
• Two selectable charge pump currents (80 µA or 640 µA typ) set via RSET resistor
• Digital lock detect and power-down mode for system efficiency

Applications

• IF/RF local oscillator generation in base stations
• Point-to-point radio local oscillator generation
• Clock generation for analog-to-digital and digital-to-analog converters
• Wireless LANs and Personal Mobile Radio (PMR) systems
• Communications test equipment

Procurement Notes

Verify the specific suffix RL against the manufacturer's current ordering guide to confirm packaging type and reel specifications. Ensure the VP supply pin is connected to a stable 13.5 V to 16.5 V source, as this differs from standard logic supplies. Confirm that the TSSOP-16 package thermal resistance requirements are met in the final PCB design.

Selection Notes

Select the ADF4113HV when the target VCO requires a tuning voltage exceeding standard 5 V limits, eliminating the need for active loop filters. Choose the appropriate prescaler setting (e.g., 16/17 for 2 GHz inputs) to ensure the prescaler output remains below 200 MHz. Verify that the required charge pump current matches the available settings or external RSET value.

Part Context

This component belongs to the ADF4113HV series, which is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002 synthesizers. It serves as the high-voltage variant within the broader ADF411x family, specifically engineered for applications where standard charge pumps cannot achieve the necessary VCO tuning range.

Replacement Considerations

Direct pin-compatible replacements include the ADF4113, ADF4112, ADF4111, and ADF4110, though these lack the 15 V charge pump capability. For lower frequency applications, the ADF4002 may be considered. Ensure any substitute meets the specific high-voltage tuning requirements if present.
