ADF4153YCPZ-RL7

Overview

The ADF4153YCPZ-RL7 is a fractional-N frequency synthesizer designed for local oscillator implementation in wireless receivers and transmitters. It features a low-noise digital phase frequency detector, precision charge pump, and programmable reference divider. The device supports RF bandwidth up to 4 GHz with an input frequency range of 10 MHz to 4 GHz. Operating on a 2.7 V to 3.3 V supply, it includes a Σ-Δ based fractional interpolator for programmable division ratios. The Y version ensures reliable performance across an extended temperature range from −40°C to +125°C.

Feature Summary

• Fractional-N architecture with Σ-Δ interpolator for precise frequency synthesis
• RF input frequency range from 10 MHz to 4 GHz
• Extended temperature operation (−40°C to +125°C) for the Y variant
• Programmable charge pump currents and separate VP pin for extended tuning voltage

Applications

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

Procurement Notes

Verify the specific ordering suffix RL7 corresponds to reel packaging requirements. Confirm that the Y suffix meets the extended industrial temperature specifications required for the target application environment before finalizing procurement.

Selection Notes

Select this component when a single-chip solution for high-frequency synthesis up to 4 GHz is needed. Ensure the external loop filter design aligns with the programmable charge pump capabilities. Verify compatibility with the 3-wire serial interface logic levels for system integration.

Part Context

This part belongs to the ADF4153 family of fractional-N frequency synthesizers. It is pin-compatible with other devices in the series such as the ADF4110, ADF4111, ADF4112, ADF4113, and ADF4106, facilitating potential design upgrades or replacements within compatible form factors.

Replacement Considerations

The ADF4153YRUZ is a pin-compatible alternative in a TSSOP-16 package. Verify that the package dimension differences between LFCSP-20 and TSSOP-16 are acceptable for the existing PCB layout.
