ADF4117BRUZ-RL

Overview

The ADF4117BRUZ-RL is an Integer-N RF PLL frequency synthesizer from Analog Devices, designed for local oscillator generation in wireless communication systems. It features a dual-modulus prescaler with a 32/33 modulus and supports RF input frequencies from 0.1 GHz to 1.2 GHz. The device operates on a single power supply ranging from 2.7 V to 5.5 V, with a typical operating current of 4.5 mA at 5 V. It includes a low-noise digital phase-frequency detector, a precision charge pump, and programmable counters (R, A, and B) controlled via a 3-wire serial interface. The component is housed in a 16-lead TSSOP package.

Feature Summary

• Supports RF input frequencies up to 1.2 GHz with a 32/33 dual-modulus prescaler.
• Operates on a single 2.7 V to 5.5 V power supply with a typical current consumption of 4.5 mA.
• Includes Fastlock mode for rapid PLL acquisition and a separate VP pin for extended tuning voltage.
• Features digital lock detect and a 3-wire serial interface for register control.

Applications

• Base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless LANs
• Communications test equipment

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging when sourcing. Confirm the 'B' grade designation corresponds to the industrial temperature range of -40°C to +85°C. Ensure the order matches the exact part number ADF4117BRUZ-RL to guarantee correct performance specifications and package type.

Selection Notes

Select this component for applications requiring integer-N synthesis up to 1.2 GHz. The ADF4117 utilizes a 32/33 prescaler, distinguishing it from the ADF4116 which uses an 8/9 prescaler. Ensure the external loop filter and VCO are compatible with the charge pump output characteristics and the available tuning voltage range provided by the VP pin.

Part Context

The ADF4117 is part of the ADF411x family, which also includes the ADF4116 and ADF4118. These devices share similar architectures but differ in maximum RF input frequency and prescaler modulus. The ADF4117 specifically bridges the gap between the lower frequency ADF4116 and the higher frequency ADF4118, offering a 1.2 GHz limit with a 32/33 prescaler.

Replacement Considerations

ADF4116BRUZ-RL: Lower frequency limit (550 MHz) with 8/9 prescaler. ADF4118BRUZ-RL: Higher frequency limit (3.0 GHz) with 32/33 prescaler. Direct substitution requires verifying that the system's frequency requirements and loop filter design accommodate the specific prescaler modulus and frequency range of the replacement part.
