ADF4153BCP

Overview

The ADF4153BCP is a fractional-N frequency synthesizer designed for local oscillator implementation in wireless receiver and transmitter upconversion and downconversion sections. It integrates a low-noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The device features a Σ-Δ based fractional interpolator allowing programmable fractional-N division via INT, FRAC, and MOD registers. It operates on a 2.7 V to 3.3 V power supply with a separate VP pin for extended tuning voltage. The component supports an RF bandwidth up to 4 GHz and includes a 3-wire serial interface for register control.

Feature Summary

• RF input bandwidth extending to 4 GHz
• Programmable fractional modulus using Σ-Δ interpolation
• Separate VP pin allows extended tuning voltage up to 5.5 V
• 3-wire serial interface for register configuration

Applications

• CATV equipment
• Base stations for mobile radio (GSM, PCS, DCS, WiMAX, CDMA, W-CDMA)
• Wireless handsets
• Communications test equipment

Procurement Notes

Verify the specific package variant required, as the B version typically denotes industrial temperature range (-40°C to +85°C). Confirm if the Y version (-40°C to +125°C) is needed for extended thermal environments. Ensure the ordering suffix matches the desired tape and reel or tray packaging format specified by the manufacturer.

Selection Notes

Select the ADF4153BCP when a fractional-N synthesizer with an RF input up to 4 GHz is required. Ensure the external VCO tuning voltage does not exceed the VP pin maximum rating of 5.5 V. Verify that the system can accommodate the 2.7 V to 3.3 V supply rails and that the 3-wire serial interface timing constraints are met by the host controller.

Part Context

The ADF4153BCP belongs to the ADF4153 family of fractional-N frequency synthesizers from Analog Devices. It is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106, facilitating design upgrades or replacements within existing architectures that utilize these legacy integer-N or earlier fractional-N devices.

Replacement Considerations

The ADF4153BCP is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106. When substituting these parts, verify that the loop filter design remains stable, as the ADF4153 offers programmable charge pump currents and fractional-N capabilities not present in the integer-N predecessors.
