Fractional-N Frequency Synthesizer  
Data Sheet  
ADF4154  
FEATURES  
GENERAL DESCRIPTION  
RF bandwidth to 4 GHz  
2.7 V to 3.3 V power supply  
Separate VP allows extended tuning voltage  
Programmable dual-modulus prescaler 4/5, 8/9  
Programmable charge pump currents  
3-wire serial interface  
The ADF4154 is a fractional-N frequency synthesizer that  
implements local oscillators in the up conversion and down  
conversion sections of wireless receivers and transmitters. It  
consists of a low noise digital phase frequency detector (PFD),  
a precision charge pump, and a programmable reference divider.  
There is a Σ-Δ based fractional interpolator to allow programmable  
fractional-N division. The INT, FRAC, and MOD registers define  
an overall N-divider (N = (INT + (FRAC/MOD))). In addition,  
the 4-bit reference counter (R-counter) allows selectable REFIN  
frequencies at the PFD input. A complete phase-locked loop (PLL)  
can be implemented if the synthesizer is used with an external  
loop filter and a voltage-controlled oscillator (VCO).  
Digital lock detect  
Power-down mode  
Pin compatible with the ADF4110/ADF4111/  
ADF4112/ADF4113, ADF4106, ADF4153  
Programmable modulus on fractional-N synthesizer  
Trade-off noise vs. spurious performance  
Fast-lock mode with built-in timer  
Loop filter design possible with ADIsimPLL™  
A key feature of the ADF4154 is the fast-lock mode with a built-  
in timer. The user can program a predetermined countdown  
time value so that the PLL remains in wide bandwidth mode,  
instead of the user having to control this time externally.  
APPLICATIONS  
Base stations for mobile radio (WiMAX, PHS, GSM, PCS, DCS,  
CDMA, PMR, W-CDMA, supercell 3G)  
Wireless handsets (PMR, GSM, PCS, DCS, CDMA, WCDMA)  
CATV equipment  
Control of all 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.
