Description

General part information

ADF4252 Series

The ADF4252 is a dual fractional-N/integer-N frequency synthesizer that can be used to implement local oscillators (LO) in the upconversion and downconversion sections of wireless receivers and transmitters. Both the RF and IF synthesizers consist of a low noise digital phase frequency detector (PFD), a precision charge pump, and a programmable reference divider. The RF synthesizer has a Σ-Δ-based fractional interpolator that allows programmable fractional-N division. The IF synthesizer has programmable integer-N counters. A complete phase-locked loop (PLL) can be implemented if the synthesizer is used with an external loop filter and voltage controlled oscillator (VCO).Control of all the on-chip registers is via a simple 3-wire interface. The device operates with a power supply ranging from 2.7 V to 3.3 V and can be powered down when not in use.ApplicationsBase stations for mobile radio (GSM, PCS, DCS, CDMA, WCDMA)Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)Wireless LANsCommunications test equipmentCATV equipment
