ADF4153YCPZ-RL

Overview

The ADF4153YCPZ-RL7 is a fractional-N frequency synthesizer from Analog Devices, designed for local oscillator generation in wireless transceivers. It features an RF input bandwidth up to 4 GHz and operates on a 2.7 V to 3.3 V supply. The Y-version variant supports an extended industrial temperature range of −40°C to +125°C. Key internal components include a low-noise digital phase-frequency detector, a programmable charge pump, and a third-order Σ-Δ fractional interpolator. The device utilizes a 3-wire serial interface for register control and includes separate power supplies for analog and digital sections to minimize noise coupling.

Feature Summary

• Fractional-N architecture with a third-order Σ-Δ interpolator for programmable modulus
• RF input frequency range from 10 MHz to 4 GHz
• Programmable charge pump currents ranging from 312.5 µA to 5 mA via external RSET resistor
• Extended temperature rating (−40°C to +125°C) for the Y-version

Applications

• Base stations for mobile radio including GSM, PCS, DCS, WiMAX, and W-CDMA
• Wireless handsets supporting GSM, PCS, DCS, CDMA, and W-CDMA standards
• CATV equipment and wireless LANs
• Communications test equipment

Procurement Notes

Verify that the specific suffix 'Y' corresponds to the extended temperature grade (-40°C to +125°C) as defined in the manufacturer's ordering guide. Confirm the package type matches the required footprint, as the ADF4153 series is available in both LFCSP-20 and TSSOP-16 configurations. Ensure compatibility with the EV-ADF4153SD1Z evaluation board if hardware validation is planned.

Selection Notes

Select the ADF4153YCPZ-RL7 when operation above 85°C is required, as this distinguishes it from the standard B-version. Designers must account for the separate VP pin, which allows tuning voltages up to 5.5 V independent of the 3.3 V logic supply. Use ADIsimPLL software to optimize loop filter design and ensure consistent RF output phase performance across the operating temperature range.

Part Context

This component belongs to the ADF4153 family of fractional-N synthesizers. It is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106, facilitating direct upgrades or replacements in existing designs. The Y-suffix specifically denotes the extended temperature capability compared to the standard industrial grade variants within the same product line.

Replacement Considerations

The ADF4153 is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106. Verify that the replacement part number matches the required temperature grade (Y vs. B) and package style (LFCSP vs. TSSOP) before substitution.
