ADF4153BRUZ-RL

Overview

The ADF4153BRUZ-RL is a fractional-N frequency synthesizer manufactured by Analog Devices Inc. in a 16-lead TSSOP package. It operates on a 2.7 V to 3.3 V power supply and supports an RF input bandwidth up to 4 GHz. The device integrates a low-noise digital phase frequency detector, a precision charge pump with programmable currents, and a third-order Σ-Δ fractional interpolator. Control is managed via a simple 3-wire serial interface. The B version operates within a temperature range of −40°C to +85°C.

Feature Summary

• Fractional-N PLL architecture with integrated Σ-Δ interpolator for programmable division ratios.
• RF input frequency range from 0.5 GHz to 4.0 GHz.
• Programmable charge pump current ranging from 312.5 µA to 5 mA via external RSET resistor.
• Analog and digital lock detect capabilities accessible through the MUXOUT pin.

Applications

• Local oscillators for wireless handsets (GSM, PCS, DCS, CDMA, W-CDMA).
• Base stations for mobile radio communications.
• CATV equipment and wireless LAN systems.
• Communications test equipment.

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and temperature grade. The BRUZ designation indicates a TSSOP-16 package. Ensure compatibility with the required operating temperature range, as the standard B version is rated for industrial temperatures (-40°C to +85°C), while Y versions support extended ranges.

Selection Notes

Select this component when a compact, single-circuit fractional-N synthesizer is required for frequencies up to 4 GHz. Consider the separate VP pin if the application demands a tuning voltage exceeding the AVDD supply level. Verify that the external loop filter design aligns with the programmable charge pump characteristics and desired phase noise performance.

Part Context

This part belongs to the ADF4153 family of fractional-N frequency synthesizers. It is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106 series, facilitating direct upgrades or replacements in existing designs requiring similar functionality but potentially different performance specifications.

Replacement Considerations

The ADF4153WYRUZ-RL7 is a verified automotive-grade replacement offering an extended temperature range of -40°C to +125°C. Other compatible parts include the ADF4153A and variants from the ADF411x series due to pin compatibility.
