ADF4113HVBRUZ-RL7

Overview

The ADF4113HVBRUZ-RL7 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 2.7 V to 5.5 V supply and covers a frequency range of 200 MHz to 4.0 GHz. Key components include a low-noise digital phase frequency detector, programmable reference divider, dual-modulus prescaler, and selectable charge pump currents. The device supports a 3-wire serial interface and includes digital lock detect and power-down modes for efficient system integration.

Feature Summary

• High voltage charge pump supporting VCO tuning voltages up to 15 V
• Frequency range from 200 MHz to 4.0 GHz
• Two selectable charge pump currents (80 µA or 640 µA typ)
• Digital lock detect and software-controlled power-down mode

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 ordering suffix RL7 corresponds to the required reel packaging configuration. Confirm that the design accommodates the VP pin requirement of 13.5 V to 16.5 V for proper charge pump operation. Ensure the TSSOP-16 package thermal resistance is managed within the specified operating temperature range of -40°C to +85°C.

Selection Notes

Select this component when the target VCO requires a tuning voltage exceeding standard 5 V supplies. Verify that the RF input frequency falls within the 200 MHz to 4.0 GHz range. Choose the appropriate prescaler setting (8/9, 16/17, 32/33, or 64/65) to ensure the prescaler output remains below 200 MHz. Use ADIsimPLL™ for loop filter design optimization.

Part Context

This part is the high-voltage variant of the ADF4113 series. It maintains pin compatibility with the ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002 synthesizers. The primary distinction is the integrated high voltage charge pump, eliminating the need for active loop filters in high-tuning-voltage applications.

Replacement Considerations

Pin-compatible replacements include ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002. Note that these alternatives lack the 15 V charge pump capability and are suitable only if lower VCO tuning voltages are acceptable.
