ADF4113HVBCPZ-RL7

Overview

The ADF4113HVBCPZ-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 single 2.7 V to 5.5 V supply and covers an RF input frequency range of 200 MHz to 4.0 GHz. The device integrates a low noise digital phase frequency detector, programmable reference and feedback counters, and a dual-modulus prescaler. Key specifications include two selectable charge pump currents (80 µA or 640 µA typ) and a normalized phase noise floor of -212 dBc/Hz.

Feature Summary

• High Voltage Charge Pump: Supports VCO tuning voltages up to 15 V directly via passive loop filters.
• Wide Frequency Range: Covers RF input frequencies from 200 MHz to 4.0 GHz.
• Integrated Digital Lock Detect: Provides active-high lock detection for system monitoring.
• Pin Compatible: Compatible with ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002.

Applications

• 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 private mobile radio (PMR)
• Communications test equipment

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to reel packaging requirements. Confirm that the B version industrial temperature rating (-40°C to +85°C) meets the operational environment constraints. Ensure the VP supply pin is decoupled appropriately for the 13.5 V to 16.5 V operating range.

Selection Notes

Select this component when the target VCO requires a tuning voltage exceeding standard 5 V limits. Ensure the prescaler output frequency remains below 200 MHz by choosing appropriate P/P+1 values (e.g., 16/17 for 2.5 GHz inputs). Verify that the RSET resistor value aligns with the required charge pump current settings of 80 µA or 640 µA.

Part Context

This part belongs to the ADF4113HV family, which is distinguished by its high voltage charge pump capability compared to the standard ADF4113. It serves as a direct replacement for other Analog Devices synthesizers like the ADF4110 through ADF4113 in designs requiring higher VCO drive voltages without active loop filters.

Replacement Considerations

The ADF4113HV is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002. When replacing these parts, ensure the design supports the VP supply voltage range of 13.5 V to 16.5 V, as lower-voltage variants may not tolerate this potential.
