ADF4113HVBRUZ

Overview

The ADF4113HVBRUZ is an integer-N frequency synthesizer featuring a high voltage charge pump capable of driving VCOs with tuning voltages up to 15 V. It operates on a single supply ranging from 2.7 V to 5.5 V, while the charge pump power supply (VP) ranges from 13.5 V to 16.5 V. The device supports RF input frequencies between 200 MHz and 4.0 GHz. Key electrical parameters include a typical operating current of 11 mA at 5 V, two selectable charge pump currents (80 µA and 640 µA), and a normalized phase noise floor of -212 dBc/Hz. It is housed in a 16-lead TSSOP package.

Feature Summary

• High voltage charge pump outputting up to 15 V for direct drive of high-tuning-voltage VCOs
• RF frequency range spanning 200 MHz to 4.0 GHz
• Dual-modulus prescaler options: 8/9, 16/17, 32/33, or 64/65
• Digital lock detect and programmable anti-backlash pulse width

Applications

• IF/RF local oscillator generation in base stations
• Point-to-point radio LO generation
• Clock generation for analog-to-digital and digital-to-analog converters
• Wireless LANs and PMR communications
• Communications test equipment

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and reel specifications. Confirm that the VP supply voltage requirements are met by the system design, as this variant requires a separate high-voltage rail distinct from the standard logic supply. Ensure ESD precautions are observed during handling due to the sensitivity of the RF input stage.

Selection Notes

Select this component when the target VCO requires a tuning voltage exceeding the standard logic supply limits. Verify that the prescaler division ratio allows the internal counter output to remain below 200 MHz for the chosen RF frequency. Check that the available charge pump currents (80 µA or 640 µA) are sufficient for the required loop filter bandwidth and phase margin calculations.

Part Context

This part 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 this family, distinguished primarily by its ability to support VP supplies up to 16.5 V compared to the lower voltage constraints of standard counterparts.

Replacement Considerations

Direct pin-compatible replacements include the ADF4113, ADF4112, ADF4111, and ADF4110, provided the application does not require the extended 15 V charge pump capability. The ADF4106 is also listed as a compatible alternative within the same package footprint.
