ADF4153YCPZ

Overview

The ADF4153YCPZ is a fractional-N frequency synthesizer manufactured by Analog Devices Inc. It operates with a power supply ranging from 2.7 V to 3.3 V and supports an RF bandwidth up to 4 GHz. The device features a low-noise digital phase frequency detector, a precision charge pump, and a programmable reference divider. It utilizes a Sigma-Delta based fractional interpolator for programmable fractional-N division. The Y version is qualified for extended operating temperatures from -40°C to +125°C. It is housed in a 20-lead LFCSP package.

Feature Summary

• Fractional-N PLL with RF bandwidth up to 4 GHz
• Programmable fractional modulus and charge pump currents
• Extended temperature range (-40°C to +125°C) for Y version
• Separate VP pin allows extended tuning voltage up to 5.5 V

Applications

• Local oscillators in wireless receivers and transmitters
• Base stations for mobile radio (GSM, PCS, DCS, CDMA, W-CDMA)
• Wireless LANs and PMR communications
• CATV equipment and communications test equipment

Procurement Notes

Verify the specific suffix 'Y' confirms the extended temperature rating of -40°C to +125°C. Confirm the 'CPZ' suffix corresponds to the 20-lead LFCSP package. Ensure compatibility with external loop filters and VCOs as the device requires these components to form a complete phase-locked loop.

Selection Notes

Select this component when a fractional-N synthesizer with high RF bandwidth up to 4 GHz is required. The Y variant is necessary for applications requiring operation at temperatures up to +125°C. Consider the separate VP supply pin if the target VCO requires a tuning voltage exceeding the logic supply voltage.

Part Context

The ADF4153YCPZ belongs to the ADF4153 series of fractional-N frequency synthesizers. It is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106 devices, facilitating design upgrades or replacements within existing architectures that utilize these compatible parts.

Replacement Considerations

The ADF4153YCPZ is pin-compatible with the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106. Verify that the replacement part matches the required temperature grade and package type.
