ADF4113BRUZ-REEL

Overview

The ADF4113BRUZ-REEL is a single-channel, integer-N phase-locked loop (PLL) frequency synthesizer manufactured by Analog Devices Inc. It supports RF input frequencies up to 4.0 GHz and operates on a power supply ranging from 2.7 V to 5.5 V. The device features a low-noise digital phase-frequency detector, a precision charge pump with programmable currents, and a programmable dual-modulus prescaler. It utilizes a 3-wire serial interface for register control and includes hardware and software power-down modes. The component is housed in a 16-lead TSSOP package.

Feature Summary

• RF input frequency range up to 4.0 GHz
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, 64/65
• Separate charge pump supply (VP) allows extended tuning voltage in 3 V systems
• Low noise digital PFD and precision charge pump

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's current documentation to confirm packaging type and quantity. Ensure the B version industrial temperature rating (-40°C to +85°C) matches the design requirements. Cross-reference the datasheet revision F specifications with the actual component received to ensure parameter compliance.

Selection Notes

Select this component when an RF input frequency up to 4.0 GHz is required. The separate VP pin is necessary if the system uses a 3 V supply but requires higher VCO tuning voltages. Verify that the prescaler division ratio selected keeps the output frequency within the limits of the downstream CMOS counters.

Part Context

This part belongs to the ADF4110 family of RF PLL frequency synthesizers. Other members include the ADF4110 (550 MHz), ADF4111 (1.2 GHz), and ADF4112 (3.0 GHz). The ADF4113 represents the highest frequency variant in this specific series, designed for applications requiring local oscillators in upconversion and downconversion sections.
