ADF4113HVBCPZ

Overview

The ADF4113HVBCPZ is an integer-N frequency synthesizer featuring a high-voltage charge pump capable of delivering up to 15 V. Designed for direct drive of high-tuning-voltage voltage-controlled oscillators (VCOs), it operates with a 2.7 V to 5.5 V supply and supports RF input frequencies from 200 MHz to 4.0 GHz. The device integrates a low-noise digital phase-frequency detector, programmable reference divider, dual-modulus prescaler, and selectable charge pump currents. It utilizes a simple 3-wire serial interface for register control and includes digital lock detect functionality.

Feature Summary

• High-voltage charge pump outputting up to 15 V for direct VCO drive
• RF frequency range of 200 MHz to 4.0 GHz
• Pin-compatible with ADF4110, ADF4111, ADF4112, ADF4113, ADF4106, and ADF4002
• Two selectable charge pump current levels via RSET resistor

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 private mobile radio systems

Procurement Notes

Verify the specific package variant against project requirements. The datasheet indicates a transition from CP-20-1 to CP-20-6 packages for the LFCSP option. Confirm that the B version specifications align with the required industrial temperature range of -40°C to +85°C. Ensure proper decoupling for the VP pin, which requires a separate supply between 13.5 V and 16.5 V.

Selection Notes

Select this component when the target VCO requires tuning voltages exceeding standard 3.3 V or 5 V logic levels, eliminating the need for active loop filters. Verify that the RF input frequency falls within the 200 MHz to 4.0 GHz range. Ensure the prescaler value (8/9, 16/17, 32/33, or 64/65) allows the divided RF signal to remain below 200 MHz at the prescaler output.

Part Context

This part belongs to the ADF4110 family of integer-N PLL synthesizers. The HV suffix denotes the inclusion of a high-voltage charge pump, distinguishing it from standard variants like the ADF4113BCPZ. It serves as a drop-in replacement for lower-voltage counterparts in designs requiring higher VCO tuning voltages, maintaining identical pinouts and control interfaces.

Replacement Considerations

Direct pin-compatible substitutes include the ADF4110, ADF4111, ADF4112, and ADF4113. Note that these alternatives lack the high-voltage charge pump and are limited to lower tuning voltages. Ensure the replacement matches the specific package type (TSSOP or LFCSP) and revision history regarding thermal resistance values.
