PLL Frequency Synthesizer  
Data Sheet  
ADF4106  
FEATURES  
GENERAL DESCRIPTION  
6.0 GHz bandwidth  
2.7 V to 3.3 V power supply  
Separate charge pump supply (VP) allows extended  
tuning voltage in 3 V systems  
Programmable dual-modulus prescaler  
8/9, 16/17, 32/33, 64/65  
Programmable charge pump currents  
Programmable antibacklash pulse width  
3-wire serial interface  
Analog and digital lock detect  
Hardware and software power-down mode  
The ADF4106 frequency synthesizer can be used to implement  
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, a programmable reference divider, programmable  
A counter and B counter, and a dual-modulus prescaler (P/P + 1).  
The A (6-bit) counter and B (13-bit) counter, in conjunction  
with the dual-modulus prescaler (P/P + 1), implement an N  
divider (N = BP + A). In addition, the 14-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 voltage  
controlled oscillator (VCO). Its very high bandwidth means  
that frequency doublers can be eliminated in many high  
frequency systems, simplifying system architecture and  
reducing cost.
