ADF4153WYRUZ-RL7

Overview

The ADF4153WYRUZ-RL7 is a fractional-N frequency synthesizer manufactured by Analog Devices Inc., designed for local oscillator generation in wireless transceivers. It operates with a supply voltage of 2.7 V to 3.3 V and supports RF input frequencies from 0.5 GHz to 4.0 GHz. The device features a programmable charge pump, a low-noise digital phase-frequency detector, and a third-order fractional interpolator. It includes a 3-wire serial interface for register control and offers analog and digital lock detect functions. The component is qualified for automotive applications and operates within an extended temperature range of -40°C to +125°C.

Feature Summary

• Fractional-N architecture with a Σ-Δ based fractional interpolator for precise frequency synthesis up to 4 GHz.
• Extended industrial temperature range (-40°C to +125°C) designated by the 'Y' suffix.
• Programmable charge pump currents ranging from 312.5 µA to 5 mA via an external RSET resistor.
• Automotive qualification (AEC-Q100) ensuring reliability for automotive electronics.

Applications

• Base stations for mobile radio including GSM, PCS, DCS, WiMAX, CDMA, and W-CDMA.
• Wireless handsets supporting GSM, PCS, DCS, CDMA, and W-CDMA standards.
• CATV equipment requiring stable local oscillators.
• Communications test equipment.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current data sheet to confirm package type and temperature grade. The 'W' prefix may indicate a specific packaging or revision variant; consult official documentation for exact physical dimensions and reel specifications. Ensure compatibility with the EV-ADF4153SD1Z evaluation board if development support is required.

Selection Notes

Select this component when an extended operating temperature range up to 125°C is required, as indicated by the 'Y' suffix. The device requires an external Voltage Controlled Oscillator (VCO) and loop filter to complete the phase-locked loop. Designers should utilize ADIsimPLL software for loop filter calculation and noise analysis. Verify that the RF input sensitivity meets the system requirements at the target frequency.

Part Context

This part belongs to the ADF4153 family of fractional-N synthesizers. It is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106 series, facilitating direct upgrades or replacements in existing designs. The 'WYRUZ-RL7' designation specifies the Y-grade temperature version, TSSOP-16 package, and reel packaging format.

Replacement Considerations

Pin-compatible alternatives include the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106. When substituting, verify that the replacement part supports the required RF frequency range and temperature specifications. Note that integer-N variants may lack the fractional interpolation feature.
