Phase Detector/Frequency Synthesizer  
ADF4002-EP  
FEATURES  
GENERAL DESCRIPTION  
400 MHz bandwidth  
2.7 V to 3.3 V power supply  
Separate charge pump supply (VP) allows extended  
tuning voltage in 3 V systems  
Programmable charge pump currents  
3-wire serial interface  
Analog and digital lock detect  
Hardware and software power-down mode  
104 MHz phase frequency detector  
Supports defense and aerospace applications  
(AQEC standard)  
The ADF4002-EP frequency synthesizer is used to implement  
local oscillators in the upconversion and downconversion 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, and a programmable N divider.  
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). In addition,  
by programming R and N to 1, the part can be used as a stand-  
alone PFD and charge pump.  
Military temperature range: −55°C to +125°C  
Controlled manufacturing baseline  
One assembly/test site  
Additional application and technical information can be found  
in the ADF4002 data sheet.
